1. Introduction

CNSC licensees are required to implement a radiation protection program (RPP) as per section 4 of the Radiation Protection Regulations. Licensees must ensure that their RPP is commensurate with the scope and risks associated with their use of nuclear substances and radiation devices.

An effective RPP is essential for the protection of the environment and the health and safety of persons. An RPP is required for every nuclear substances and radiation devices licensee and it ensures that the licence conditions and regulatory requirements are met. It is also an important principle of radiation protection that radiation doses are kept as low as reasonably achievable (ALARA), taking into account social and economic factors.

A proposed RPP must be provided with the licence application. The application should demonstrate, with supportable evidence, how the RPP meets regulatory requirements.

Sections 2 and 3 of this document describe the roles and responsibilities of the radiation safety officer (RSO), who is responsible for overseeing the RPP. Sections 4 and 5 provide information about the elements that should be considered when developing, implementing, managing and assessing an RPP.

1.1 Purpose

This document provides guidance for nuclear substances and radiation devices licensees and applicants on how to develop, implement, manage and assess an RPP.

1.2 Scope

This document contains guidance for nuclear substances and radioactive devices licensees and applicants. Nuclear substances and radioactive devices licensed under other classes of licence may wish to consult this document for information.

Appendix B provides information for licensees and applicants with a complex program, but could also be useful for other applicants. Characteristics of a complex program include, among others:

  • consolidated use of nuclear substances licence (use type 815)
  • multiple licensed locations
  • multiple licences issued at the same location
  • multiple licences issued for the same organization

Licensees and applicants that have a complex program have medium and high-risk use types, as defined in appendix B of REGDOC-1.6.1, Licence Application Guide: Nuclear Substances and Radiation Devices [1]. Any licensee or applicant that is unsure whether it has a complex program should contact the CNSC for clarification.

1.3 Relevant legislation

The following provisions of the Nuclear Safety and Control Act (NSCA) and the Regulations made under it are relevant to this document:

2. Responsibility for Radiation Safety

The licensee is responsible for radiation safety and for the conduct of all licensed activities that are authorized under its CNSC licence. The applicant authority is an individual at the senior management level with sufficient authority for both financial and human resources, thus has the ultimate responsibility for ensuring that an RPP is implemented in accordance with all regulatory requirements. The applicant authority should delegate duties for the day-to-day oversight of the RPP, but not accountability, to an individual known as the radiation safety officer (RSO). More details on applicant authority responsibilities can be found in REGDOC-1.6.1, Licence Application Guide: Nuclear Substances and Radiation Devices [1].

RSO is the designation commonly assigned to a radiation safety specialist who administers an RPP on a day-to-day basis. RSOs are designated by the applicant authority pursuant to section 15 of the General Nuclear Safety and Control Regulations. The applicant authority designates the RSO by completing the Request to appoint a new Radiation Safety Officer form. By signing this form, the RSO agrees to take responsibility for overseeing the implementation and management of the RPP and to communicate with the CNSC for any matters pertaining to the RPP. Section 3 describes the RSO’s roles and responsibilities.

The applicant authority should ensure that sufficient resources are allocated to the RSO in order to meet all of the regulatory obligations, such as:

  • human resources to assist in managing and executing the required duties
  • sufficient authority to meet the regulatory requirements (see section 3.2)
  • administrative assistance with correspondence, record-keeping requirements and document management associated with a CNSC licence
  • financial resources to meet regulatory expectations and address non-compliance, such as for personnel training and for purchasing radiation monitoring equipment or other equipment

3. Radiation Safety Officer

The RSO is a critical component of an effective RPP. The RSO must have the authority to enforce policies and procedures established under the RPP in order to meet all regulatory requirements.

Depending on the structure and size of the licensed organization, an RSO could be designated to oversee RPP management at the corporate level (corporate RSO) and assisted by other individuals to oversee the program at the site (site RSOs) to ensure the RPP is effectively implemented and applied at the local level.

3.1 Duties

The applicant authority is accountable for ensuring adequate resources are available to implement the RPP. The applicant authority should ensure that competing duties or priorities are not assigned to the RSO that might detract significantly from their ability or availability to manage the RPP. The responsibilities of an RSO are not an adjunct to another job task; they are an essential element for ensuring the safe use of nuclear substances and radiation devices.

As best practice the applicant authority should provide the RSO with a description of the duties, as well as the number of hours the RSO should be dedicating to them. The ability of the RSO to manage the RPP should be evaluated by the applicant authority at defined intervals, in order to identify where additional time or other assistance is needed.

The RSO typically provides day-to-day administrative oversight of radiation safety. A non-exhaustive list of duties is provided in appendix A. The necessary competence in terms of educational training and practical experience required of an RSO is based on the size, scope, complexity or diversity of the licensed activities.

The RSO must be given sufficient time to properly plan, monitor, manage and conduct the activities required to demonstrate compliance with all regulatory requirements. The allocated time will be estimated by the licensee or applicant, taking into consideration the number of workers, the magnitude of operations and the geographic disparity of sites within the organization. For overseeing a complex RPP, the regulatory burden is expected to be handled by a full-time RSO. For low-risk use types, the RSO could manage the RPP on a part-time basis, while assuming other duties. Depending on the organizational size and geographic disparity of sites, additional support may be required, as described in section 3.6.2.

3.2 Authority of the RSO

The RSO must have necessary authority to implement the RPP, identify non-compliance, initiate corrective actions and verify the implementation and effectiveness of corrective actions. The RSO must have the authority to terminate any unsafe work practices that have or may potentially have a negative impact on the health and safety of any person, regardless of the potential impact this may have on the organization’s operations.

In particular, the RSO must have necessary authority to:

  1. communicate directly with the applicant authority
  2. act as signing authority on all matters of radiation safety, the CNSC licence and the obligations of the licensee
  3. immediately stop any work, task or undertaking that the RSO considers unsafe or which may contravene the NSCA, its regulations or the CNSC licence
  4. implement and enforce any changes to any work, task or undertaking which are necessary to ensure that the licensee remains compliant or returns to compliance
  5. modify any policy and any procedure, and ensure that the changes are properly documented and communicated to workers

3.3 Qualifications

The RSO must have sufficient knowledge to effectively manage activities with nuclear substances and radiation devices in accordance with the licence conditions of the CNSC licence.

The RSO is encouraged to make use of accreditation programs for RSOs which provide qualifications for the proposed use of nuclear substances and prescribed equipment. The learning objectives must be aligned with the RSO’s duties. The suitability of a training provider can be evaluated by feedback from previous clients. The RSO must have adequate knowledge of regulatory requirements and CNSC expectations, including the:

  • NSCA and its relevant regulations
  • applicable CNSC regulatory documents
  • CNSC’s licensing and compliance verification programs
  • defined authorities and responsibilities of the RSO
  • security of nuclear substances

Additional knowledge, based on the proposed licensed activities, could include:

  • source recovery activities for industrial radiography licences
  • transportation of dangerous goods for those shipping or receiving nuclear substances and radiation devices
  • contamination control and spill management techniques for those using unsealed nuclear substances
  • safe management and use of the nuclear substances and radiation devices, including any special considerations (e.g., confined spaces, biohazardous materials)

3.4 Experience

The RSO should have relevant and practical work experience in conducting the proposed licensed activities.

The CNSC expects the RSO to be familiar with the nature and characteristics of the nuclear substances and radiation devices that are to be authorized under the CNSC licence, any proposed licensed activities that will be conducted and other ancillary hazards that may impact the licensed activities.

3.5 Continuing education

RSOs must maintain their qualifications through continuing education. Refresher training should be determined based on an evaluation of the complexity, importance and frequency of the tasks assigned. A training-needs analysis should be conducted when any changes are made to the RSOs’ activities or responsibilities.

The frequency and extent of the refresher training should be determined, defined and documented. This will depend on the licensed activities authorized by the CNSC licence and the capabilities of the RSO.

As part of the refresher training, RSOs should review their knowledge of the CNSC regulatory requirements. RSOs should be made aware of any changes to regulatory requirements that may impact the licensed activities authorized under the CNSC licence. Refresher training should be provided at least every five years and when changes to regulatory requirements or licence conditions occur, or in the case of an RSO’s return after a lengthy absence.

Periodic refresher training for workers and the RSO should be part of the training program included in the RPP. More details on radiation safety training programs can be found in appendix A of REGDOC-2.2.2, Personnel Training [2].

3.6 RSO staffing

The effectiveness of the RPP must be maintained while licensed activities are being conducted. As a result, a designated alternate RSO is necessary during an RSO’s temporary absence. In addition, a site RSO may be required when multiple locations are authorized under the same RPP.

The corporate RSO or any person assigned RSO duties, such as an alternate RSO, a site RSO or a consultant, should be available while licensed activities are being performed.

3.6.1 Alternate RSO

During the RSO’S absence, an alternate RSO must be designated in order to carry on the licensed activities and ensure that continuous oversight of the RPP is maintained. The alternate RSO can also be involved with the day-to-day management of the RPP as an assistant to the RSO.

For short-term absences, such as vacation, illness or injury, the alternate RSO should, at a minimum, have knowledge of the regulatory requirements of the licensed activity and all reporting requirements. The CNSC should be notified in the case of short-term absences. RSO training for alternate RSOs is recommended.

In the case of long-term absences, such as maternity or parental leave, temporary assignment to other duties, severe illness or injury, the alternate RSO must have the same level of knowledge about and training on the licensed activities and the regulatory requirements as the RSO. The Request to Appoint a Radiation Safety Officer or an Alternate Radiation Safety Officer form must be completed and submitted to notify the CNSC of the replacement.

3.6.2 Site RSO

When a licence application to conduct licensed activities in more than one geographical location is submitted, a site RSO should be appointed at each licensed location to implement and maintain the RPP. The purpose of designating a site RSO is to ensure direct RPP oversight at all locations. The site RSO can be designated by the corporate RSO.

The site RSO should report to the corporate RSO on all radiation protection matters. The site RSO should have similar levels of experience, training and authority as the corporate RSO. The roles and responsibilities and the lines of authority for the site RSO must be clearly defined. It should be clear that the corporate RSO remains the person responsible for overseeing the overall RPP and is the main liaison with the CNSC.

3.6.3 Consultant

If there are no qualified or available personnel to assume the role of the RSO, it is acceptable to contract an independent consultant to serve as the corporate or site RSO. The consultant must have the same level of knowledge about and training on the licensed activities and the regulatory requirements as is expected of an RSO. In addition, the licensee or applicant must ensure that the consultant can spend enough time at the licensed location to oversee the RPP, even if that individual is managing several programs simultaneously.

4. Development and Implementation of an Effective RPP

The RPP submitted as part of the licence application is the licensee’s proposal on how it intends to comply with regulatory requirements. As such, the RPP is referenced in the appendix to the licence, and its implementation is verified during inspections by the CNSC.

An effective RPP is typically developed, implemented and managed to suit the licensed activity, complexity and circumstances of the licensee. The RPP is normally developed by the RSO in collaboration with specialists and other relevant staff. To ensure radiation safety and compliance with the relevant requirements, a typical RPP includes operating policies and procedures that demonstrate its effectiveness and describe how it will be maintained. REGDOC-1.6.1, Licence Application Guide: Nuclear Substances and Radiation Devices [1] provides a comprehensive list of policies and procedures that must be submitted as part of a licence application. Additional information on the content of an RPP can be found in REGDOC-2.7.1, Radiation Protection.

The fundamental elements of an RPP are procedures and people. The RPP includes procedures that inform and direct persons who use or oversee the use of nuclear substances and radiation devices. In order to successfully maintain effective control and oversight of the RPP, the necessary authority, financial and physical resources must be allocated to the RSO, such as the facilities and equipment required for developing, implementing and maintaining the program.

5. Management System

An effective management system helps ensure that safety is properly considered in all decisions and actions. It ensures that the organization is aligned with top management direction and able to establish, communicate and achieve the objectives and priorities it sets for itself. REGDOC-2.1.1, Management System [3] outlines management system principles, including:

  1. the business is defined, planned and controlled
  2. the organization is defined and understood
  3. personnel are competent at the work they do
  4. personnel know what is expected of them
  5. work is planned
  6. experience is sought, shared and used
  7. information is provided in a timely manner to the people who need it
  8. the performance of work is controlled
  9. the preparation and distribution of documents are controlled
  10. work is verified to confirm that it is correct
  11. problems are identified and resolved
  12. changes are controlled
  13. records are maintained
  14. assessments are performed

The following subsections describe four important management system components that should be included in the RPP: safety culture, assessment of the RPP, event investigation and documentation.

5.1 Safety culture

A healthy safety culture is a key factor in minimizing the likelihood of safety-related events and mitigating their potential impact. Fostering a healthy safety culture is an important aspect of ensuring that the oversight of radiation safety is commensurate with the defined complexity and risks inherent in the licensed activities and the RPP.

The CNSC defines safety culture as "the characteristics of the work environment, such as the values, rules, and common understandings that influence employee perceptions and attitudes about the importance that the organization places on safety."

A healthy safety culture evolves from the development and application of a questioning attitude at all levels of the organization, including management. Fostering a healthy safety culture requires support and commitment at all levels of management within the organization. It also relies equally on the mutual commitment of the applicant authority, RSOs and workers. Managers at all levels should strive to promote a healthy safety culture within the workplace. All individuals in the organization are expected to help foster and sustain that culture.

Understanding an organization’s safety culture is an important part of fostering a healthy safety culture. The development of a shared understanding of the perceptions and attitudes of both the workers and management is vital to maintaining and improving radiation safety.

Licensees or applicants may foster a healthy safety culture by:

  1. promoting the commitment to protection and safety at all levels of the organization
  2. ensuring a common understanding of the key principles of the safety culture within the organization
  3. providing the means by which the organization supports individuals and teams so they can carry out their tasks safely and effectively, taking into account the interactions between individuals, technology and the organization
  4. encouraging workers and their representatives and other relevant persons to participate in the development and implementation of policies, rules and procedures that deal with protection and safety
  5. ensuring the accountability of the organization and of individuals at all levels for protection and safety
  6. encouraging open communication about protection and safety within the organization and with relevant parties, as appropriate
  7. encouraging a questioning attitude to challenge prevailing assumptions with respect to the planning and execution of work
  8. encouraging the development and maintenance of processes that promote transparency, continuous learning and improvement
  9. providing the means by which the organization continually seeks to better understand, develop and strengthen its safety culture
  10. providing a safe work environment that enables reporting without fear of reprisal

From time to time, it is important to reflect on the maturity of the organization’s safety culture. At Stage 1, there is an awareness of the risks associated with a job, the ability to use appropriate safety equipment or proper work control methods to mitigate those risks, and management reinforcement of appropriate safety practices. For further information and guidance on how to assess and improve safety culture, see appendix C of REGDOC-2.1.2, Safety Culture [4].

5.2 Assessment of the RPP

The RPP should include means to periodically assess the performance of the program. This may be performed through self-assessments, independent assessments or management reviews. The RPP should define the type(s) of assessment(s) to perform, the frequency and the method(s) to be used. Note: An inspection performed by a CNSC inspector is not considered an assessment activity.

The results of these assessments should be documented and shared with the applicant authority and with the radiation safety committee (RSC), if one has been established. A follow-up of the deficiencies identified and their corrective actions should be conducted to ensure the items of non-compliance are properly resolved.

Assessments ensure that the RPP is adequate, up to date and implemented in accordance with the ALARA principles. The information collected during the assessments may be used to improve any weaknesses identified.

Although the RPP should be assessed at least every five years, the frequency of the assessments will depend on the complexity of the RPP and the risk associated with the licensed activity. The frequency and the chosen method(s) should be defined and documented in the RPP. The basis of the assessments may need to be expanded to account for different use types, associated hazards and mitigating controls.

These assessments can be carried out using checklists, document reviews, observations of actual work being performed against procedures and staff interviews. The following are some examples of elements that could be included in the assessment of the RPP. This is not a comprehensive list:

  1. governance documentation
  2. workers’ training and authorization
  3. licensed activities carried out by workers
  4. inventory of unsealed sources, sealed sources and radiation devices
  5. licensed activities (use, store, transfer, import and export)
  6. leak tests of sealed sources
  7. location of use
  8. dose records (dosimetry and dose estimates)
  9. policies and procedures to ensure they are consistent with current regulatory requirements
  10. use and storage areas (contamination and dose rate)
  11. calibration of radiation detection instruments performed at the prescribed frequency
  12. waste handling
  13. decommissioning records
  14. past events
  15. maintenance of records
  16. appropriate use of radiation warning signs
  17. posting of 24-hour emergency contact
  18. room classification
  19. control of authorized rooms (accessible to authorized users)
  20. transport requirements
  21. import/export restrictions and requirements
  22. emergency management and unplanned events procedure accuracy and applicability

5.2.1 Self-assessments

Self-assessments, such as internal audits or inspections, are vital in evaluating the implementation and effectiveness of the RPP. Self-assessments are generally conducted by the RSO to assess the work practices against requirements established in the RPP and to identify opportunities for improvement. These assessments are also conducted to confirm that the work being performed in their area of responsibility meets the requirements of the RPP. They may be planned or unplanned.

The RPP should describe the frequency of self-assessments and describe the elements that will be assessed. The frequency should be determined based on the complexity of the licensed activities and the results of previous assessments, with specific regard to deficiencies identified. Based on best practices, self-assessments should be performed at least annually, or in response to significant changes in the organization’s licensed activities or the identification of weaknesses in safety.

The list of examples of Type II inspection worksheets on the CNSC’s website can be useful when developing a self-assessment policy and procedure.

5.2.2 Independent assessments

Independent assessments are often referred to as external audits and are planned and carried out by an external organization at defined frequencies. The primary objective of an independent assessment is to confirm that the documented RPP meets the requirements and that the implementation of the RPP is effective.

The results of independent assessments are reported to the applicant authority or to the management level with sufficient authority to resolve the issues identified.

Independent assessments should be based on the results of self-assessments. They should also be conducted after substantive changes to work practices have been implemented.

5.2.3 Management reviews

Management reviews are conducted by the applicant authority at a set frequency as an oversight activity to assess the effectiveness of the RPP and to proactively make improvements as required.

The frequency of the management reviews should be defined in the RPP and should be based on the complexity of the licensed activities, the occurrence of major changes to the licensed activities or as a result of event investigations.

The results of self- and independent assessments should form the basis for decisions and actions at management review meetings. Management reviews should be documented and communicated to staff as necessary. Problems identified should be tracked and the appropriate corrective actions should be established as described in the RPP.

5.3 Event investigation

In accordance with the regulatory requirements established in the General Nuclear Safety and Control Regulations, Radiation Protection Regulations, and Packaging and Transport of Nuclear Substances Regulations, 2015, an investigation must be conducted to determine the probable cause of an event. Event investigation is a formal process to identify the probable cause or causes of an event, including the technical issues and organizational factors underlying the event. This determination is also used to help develop corrective actions to restore the effectiveness of the RPP and to prevent the occurrence of a similar event. All events in which a loss of control or a deviation from the RPP occurs must be immediately controlled, documented and evaluated for significance.

When regulatory limits are exceeded or events are determined to be systematic (e.g., recurring action level exceedances), a detailed event report must be provided to CNSC staff. It should contain the following information, as far as practicable and applicable:

  1. a summary of any analysis completed, including the cause(s) and the conclusion(s) drawn from the investigation(s) after the event
  2. a description of the resulting effects on the health, safety and security of persons and the environment
  3. the effective dose and equivalent dose of radiation received by any person as a result of the event, including the measured or estimated doses to personnel and the public as a consequence of the event
  4. the actions that have been taken or proposed, including actions identified and taken to restore the effectiveness of the RPP
  5. any review of a comparable event

The corrective actions taken to resolve problems associated with the event need to be accepted by the applicant authority and the RSO, and be evaluated for effectiveness during a periodic management review.

5.4 Documentation

The RPP should contain all necessary operational information for working with nuclear substances and radiation devices. It should be the first point of reference for workers and provide all necessary policies and procedures. The specific details of the RPP are usually documented in a radiation safety manual, which is submitted as part of the licence application. The radiation safety manual should be signed and dated by the RSO and applicant authority to confirm that the published version of the manual was reviewed and approved. It is recommended that the RPP be reviewed periodically and updated as necessary to reflect any changes to policies, procedures and regulatory requirements. The frequency of the reviews should be determined, defined and documented. It is important to note that the licensee is to inform and submit any changes made to CNSC licensing staff for review and approval prior to implementing the new version of the radiation safety manual.

It is important to ensure that revisions include version control and that they are signed and dated by the RSO and applicant authority. Workers must be given training on the changes or modifications made in any policies and procedures within the radiation safety manual. For good practices in writing technical procedures, see:

  • Procedure Writing: Principles and Practices [5]
  • Procedure Writers’ Manual [6]
  • Procedure Process Description [7]
  • Guidance for Preparing Standard Operating Procedures [8]
  • Procedure Writer’s Guide, Licensee Document: ML111820250 [9]

Appendix A: Duties of the RSO

The duties of the RSO may vary depending on the licensed activity. The following list includes examples of tasks that may be required of the RSO. It is organized by safety and control area (SCA).

  • provide support in decommissioning tasks

Appendix B: Radiation Safety Committee

The additional information included in this appendix should be considered when developing a complex RPP. It is recommended that licensees and applicants with complex programs establish a radiation safety committee (RSC). The RSC may have corporate responsibilities for radiation safety, or it may simply have an advisory or evaluation role. Depending on the complexity and risk inherent in the RPP, the RSC may require that designated policies and procedures are approved by the committee before implementation.

B.1 RSC Role and Responsibilities

The role and responsibilities of an RSC may be to provide advice or direction on radiation safety matters and to ensure the implementation and oversight of an effective RPP. Such committees are usually established or retained with the approval of the applicant authority.

The RSC works with the applicant authority and the RSO to define, plan and control the RPP implementation to ensure that it is aligned and integrated with the core business objectives of the licensed activity. As such, the RSC should be involved in establishing policies and procedures for managing the RPP. The role of the RSC may include the following:

  1. oversee the RPP and radiation safety matters
  2. advise on radiation safety matters, including the safe use of nuclear substances and radiation devices during licensed activities
  3. ensure that radiation exposures are maintained ALARA
  4. review all proposed uses of nuclear substances and radiation devices and determine whether they comply with the RPP and regulatory requirements
  5. assess the adequacy and the effectiveness of the training programs
  6. review the results of RPP assessments
  7. discuss positive and negative operational experiences to determine where improvement is needed
  8. review any reports concerning events or unusual occurrences
  9. recommend corrective measures or improvements when the review or assessment identifies deficiencies
  10. recommend measures or improvements to prevent the reoccurrence of any events
  11. advise the applicant authority of any need for additional resources to establish, maintain or improve RPP effectiveness

The RSC should maintain written records of their meetings, as detailed in section B.4.

B.2 Membership

RSCs should include members selected or appointed because of their expertise or involvement in radiation safety matters. Collectively, these members should advise their managers and RSOs on radiation safety matters in general and on the RPP effectiveness within the organization in particular. RSC members may participate on a full-time or part-time basis.

The RSC should comprise members from multiple disciplines. An RSC should include at least corporate and site RSOs, an authorized user from each type of licensed activity, a representative of the auxiliary personnel (e.g., clerical, janitorial, security), a representative of the nursing service where applicable (therapeutic nuclear medicine licence) and a representative of management. The RSC may also include physicians, physicists and representatives of corporate interest groups, such as managers (senior staff members), workers or specific user units. It should also include a representative of the health and safety committee. Every department that receives occupational dose or has an impact on radiation exposure or safety should also be represented.

When selecting a chairperson for the committee, several factors should be considered, such as knowledge of radiation safety and leadership abilities. The chairperson should have sufficient time to devote to this position in addition to other responsibilities. In general, the RSO should not be appointed chairperson of the RSC, since the RSO is responsible for the day-to-day oversight of the RPP and may be too closely involved in the licensed activities to be objective.

The chairperson should work closely with the applicant authority to ensure effective decisions are made and carried out.

The corporate RSO’s participation is essential, as is that of a site RSO from each authorized location.

B.3 Terms of Reference

The RSC’s terms of reference depend on individual circumstances, such as management decisions, corporate procedures, available resources, licence requirements and the magnitude, diversity or complexity of the licensed activities. The terms of reference should contain the following:

  1. committee’s decision-making system
  2. quorum requirements
  3. membership
  4. RSC roles and responsibilities (refer to section B.1)
  5. RSC members’ roles and responsibilities
  6. required meeting agenda items
  7. meeting frequency

The terms of reference should be part of the RPP.

B.4 Meetings

Meetings are vital to the effective functioning of the committee and its ability to provide oversight on matters pertinent to radiation safety. They are necessary for decision making, problem solving, discussing issues, and reviewing and approving the policies and procedures that form the radiation safety program.

A quorum should ensure a minimum participation. Quorum can be a majority but has to be defined according to the needs and the purposes of the committee. An RSC meeting should be held as necessary, but at least annually. The circumstances that can trigger a non-routine meeting should also be described in the terms of reference.

Written minutes and any associated actions should be maintained for future reference and circulated to all committee members. The minutes should include the date of the meeting, the members present and absent to demonstrate quorum was respected, a summary of the discussions, recommendations and any decisions made during the meeting.

The RSC depends on the RSO’s experience with the details of the RPP and applicable regulatory requirements, since RSC members do not have the same level of knowledge in radiation safety.
