Regulations are current to 2017-11-06 and last amended on 2017-09-22. Previous Versions

Emergencies

  •  (1) The effective dose limits and equivalent dose limits prescribed in sections 13 and 14 do not apply to a person participating in the control of an emergency.

  • (2) A licensee who requests a person to participate in the control of an emergency shall ensure that the person does not receive an effective dose greater than 50 mSv or an equivalent dose to the skin greater than 500 mSv unless that person is taking an emergency action described in Column 1 of the table to subsection (3).

  • (3) A licensee who requests a person participate in the control of an emergency shall ensure, if that person takes an emergency action described in Column 1 of the table to this subsection, that the person does not receive an effective dose greater than that described in Column 2 or an equivalent dose to the skin greater than that described in Column 3.

    3Actions to prevent the development of conditions that could significantly affect people and the environment5005 000
  • (4) If, on the request of a licensee, a person takes actions described in more than one item of the table to subsection (3), the licensee shall ensure that the effective dose received by that person does not exceed 500 mSv and that the equivalent dose to the skin received by that person does not exceed 5 000 mSv.

  • (5) A licensee shall limit the effective dose and equivalent dose received by and committed to persons participating in the control of an emergency to as low as is reasonably achievable, social and economic factors being taken into account.

  • (6) A licensee shall notify as soon as feasible the person who received the dose of radiation and the Commission in the event that the licensee becomes aware that any of the dose limits prescribed in subsection (2), (3) or (4) may have been exceeded.

  • (7) A licensee shall not request that a pregnant woman participate in the control of an emergency.

  • (8) The dose limits prescribed by subsections (2), (3) and (4) and sections 13 and 14 may be exceeded by a person who acts voluntarily to save or protect human life.

  • SOR/2017-199, s. 1.

When Dose Limit Exceeded

 When a licensee becomes aware that a dose of radiation received by or committed to a person or an organ or tissue may have exceeded an applicable dose limit prescribed by section 13 or 14, the licensee must

  • (a) immediately notify the person and the Commission of the dose;

  • (b) require the person to leave any work that is likely to add to the dose;

  • (c) conduct an investigation to determine the magnitude of the dose and to establish the causes of the exposure;

  • (d) identify and take any action required to prevent the occurrence of a similar incident; and

  • (e) within 21 days after becoming aware that the dose limit has been exceeded, report to the Commission the results of the investigation or on the progress that has been made in conducting the investigation.

  • SOR/2017-199, s. 2.

Authorization of Return to Work

 When the Commission or a designated officer authorized under paragraph 37(2)(h) of the Act authorizes the return to work of a person referred to in section 16, the authorization may specify conditions to protect the health and safety of the person.

  • SOR/2017-199, s. 3.

Dosimetry Services

Application for Licence to Operate

 An application for a licence to operate a dosimetry service shall contain the following information in addition to the information required by section 3 of the General Nuclear Safety and Control Regulations:

  • (a) a description of the proposed operation of the dosimetry service;

  • (b) the proposed quality assurance program;

  • (c) the types of dosimetry services proposed to be provided, including the types of radiation that will be monitored and their respective energy ranges;

  • (d) the precision, accuracy and reliability of the dosimetry services to be provided; and

  • (e) the proposed qualification requirements and training program for workers.

Obligations of Licensees

 Every licensee who operates a dosimetry service shall file with the National Dose Registry of the Department of Health, at a frequency specified in the licence and in a form compatible with the Registry, the following information with respect to each nuclear energy worker for whom it has measured and monitored a dose of radiation:

  • (a) the worker’s given names, surname and any previous surname;

  • (b) the worker’s Social Insurance Number;

  • (c) the worker’s sex;

  • (d) the worker’s job category;

  • (e) the date, province and country of birth of the worker;

  • (f) the amount of exposure of the worker to radon progeny; and

  • (g) the effective dose and equivalent dose received by and committed to the worker.

Labelling and Signs

Labelling of Containers and Devices

  •  (1) No person shall possess a container or device that contains a radioactive nuclear substance unless the container or device is labelled with

    • (a) the radiation warning symbol set out in Schedule 3 and the words “RAYONNEMENT — DANGER — RADIATION”; and

    • (b) the name, quantity, date of measurement and form of the nuclear substance in the container or device.

  • (2) Subsection (1) does not apply in respect of a container or device

    • (a) that is an essential component for the operation of the nuclear facility at which it is located;

    • (b) that is used to hold radioactive nuclear substances for current or immediate use and is under the continuous direct observation of the licensee;

    • (c) in which the quantity of radioactive nuclear substances is less than or equal to the exemption quantity; or

    • (d) that is used exclusively for transporting radioactive nuclear substances and labelled in accordance with the Packaging and Transport of Nuclear Substances Regulations, 2015.

  • SOR/2015-145, s. 46.

Posting of Signs at Boundaries and Points of Access

 Every licensee shall post and keep posted, at the boundary of and at every point of access to an area, room or enclosure, a durable and legible sign that bears the radiation warning symbol set out in Schedule 3 and the words “RAYONNEMENT-DANGER-RADIATION”, if

  • (a) there is a radioactive nuclear substance in a quantity greater than 100 times its exemption quantity in the area, room or enclosure; or

  • (b) there is a reasonable probability that a person in the area, room or enclosure will be exposed to an effective dose rate greater than 25 µSv/h.

  • SOR/2007-208, s. 9.

Use of Radiation Warning Symbol

 Whenever the radiation warning symbol set out in Schedule 3 is used,

  • (a) it shall be

    • (i) fully visible,

    • (ii) of a size appropriate for the size of the container or device to which it is affixed or attached, or the area, room or enclosure in respect of which it is posted,
