Regulations are current to 2021-09-11 and last amended on 2021-01-01. Previous Versions

Obligations of Licensees and Nuclear Energy Workers (continued)

Provision of Information

  •  (1) Every licensee must inform each nuclear energy worker, in writing,

    • (a) of the fact that the worker is a nuclear energy worker;

    • (b) of the risks associated with radiation to which the worker may be exposed in the course of their work;

    • (c) of the applicable effective dose limits and equivalent dose limits prescribed by sections 13 to 15;

    • (d) of the worker’s radiation dose levels, received on an annual basis; and

    • (e) of the worker’s responsibilities during an emergency and the risks associated with radiation to which the worker may be exposed during the control of an emergency.

  • (2) Every licensee must inform each female nuclear energy worker, in writing,

    • (a) of the risks associated with the exposure of embryos and fetuses to radiation and the risks to breastfed infants from the intake of nuclear substances;

    • (b) of the importance of informing the licensee, as soon as feasible, in writing, that the female nuclear energy worker is pregnant or breastfeeding;

    • (c) of the rights of a pregnant nuclear energy worker and the rights of a breastfeeding nuclear energy worker under section 11; and

    • (d) of the applicable effective dose limits for pregnant nuclear energy workers prescribed by section 13.

  • (3) Every licensee must obtain from each nuclear energy worker who is informed of the matters referred to in paragraphs (1)(a) and (b) and subsection (2) a written acknowledgement that the worker has received the information.

Requirement to Use Licensed Dosimetry Service

  •  (1) Every licensee must use a licensed dosimetry service to measure and monitor the doses of radiation received by and committed to nuclear energy workers who have a reasonable probability of receiving

    • (a) an effective dose that is greater than 5 mSv in a one-year dosimetry period; or

    • (b) an equivalent dose to the skin, or the hands and feet, that is greater than 50 mSv in a one-year dosimetry period.

  • (2) Every licensee referred to in subsection (1) must provide the following information to the licensed dosimetry service with respect to each nuclear energy worker referred to in subsection (1):

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

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

    • (c) the worker’s gender;

    • (d) the worker’s job category; and

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

Collection of Personal Information

 If a licensee collects personal information, as defined in section 3 of the Privacy Act, that may be required to be disclosed to the Commission, another government institution, as defined in that section, or a licensed dosimetry service, the licensee must inform the person to whom the information relates of the purpose for which it is being collected.

Nuclear Energy Workers

 Every nuclear energy worker shall, on request by the licensee, inform the licensee of the worker’s

  • (a) given names, surname and any previous surname;

  • (b) Social Insurance Number;

  • (c) the worker’s gender;

  • (d) date, province and country of birth; and

  • (e) dose record for the current one-year and five-year dosimetry periods.

Pregnant and Breastfeeding Nuclear Energy Workers

  •  (1) On being informed by a female nuclear energy worker, in writing, that she is pregnant, the licensee must, in order to comply with section 13, make any accommodation that will not result in costs or business inconvenience constituting undue hardship to the licensee.

  • (2) On being informed by a female nuclear energy worker, in writing, that she is breastfeeding an infant, the licensee must, in order to limit intakes of nuclear substances by the worker, make any accommodation to the working conditions that will not result in costs or business inconvenience constituting undue hardship to the licensee.

  •  (1) [Repealed, SOR/2020-237, s. 13]

  • (2) For the purposes of sections 13 and 14, doses of radiation include those received from X-rays or other man-made sources of radiation.

Effective Dose Limits

  •  (1) Every licensee must ensure that the effective dose received by and committed to a person described in column 1 of the table to this subsection, during the period set out in column 2, does not exceed the effective dose set out in column 3.

  • (4) [Repealed, SOR/2020-237, s. 14]

  • (5) For the purpose of subsection (1), where the end of a dosimeter-wearing period or a bioassay-sampling period does not coincide with the end of a dosimetry period set out in column 2 of the table to that subsection, the licensee may extend or reduce the dosimetry period to a maximum of two weeks so that the end of the dosimetry period coincides with the end of the dosimeter-wearing period or biossay-sampling period, as the case may be.

Equivalent Dose Limits

  •  (1) Every licensee must ensure that the equivalent dose received by and committed to an organ or tissue set out in column 1 of the table to this subsection, of a person described in column 2, during the period set out in column 3, does not exceed the equivalent dose set out in column 4.

  • (2) For the purpose of subsection (1), where a dosimeter-wearing period or a bioassay-sampling period extends beyond the end of a dosimetry period set out in column 3 of the table to that subsection, the period is extended to the end of the dosimeter-wearing or bioassay-sampling period or by two weeks, whichever extension is shorter.

  • (3) When skin is unevenly irradiated, the equivalent dose received by the skin is the average equivalent dose over the 1 cm2 area that received the highest equivalent dose.
