15. (1) During the control of an emergency and the consequent immediate and urgent remedial work, the effective dose and the equivalent dose may exceed the applicable dose limits prescribed by sections 13 and 14, but the effective dose shall not exceed 500 mSv and the equivalent dose received by the skin shall not exceed 5 000 mSv.
(2) Subsection (1) does not apply in respect of pregnant nuclear energy workers who have informed the licensee in accordance with subsection 11(1).
(3) The dose limits prescribed by sections 13 and 14 and subsection (1) may be exceeded by a person who acts voluntarily to save or protect human life.
When Dose Limit Exceeded
16. When a licensee becomes aware that a dose of radiation received by and committed to a person or an organ or tissue may have exceeded an applicable dose limit prescribed by section 13, 14 or 15, the licensee shall
(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.
Authorization of Return to Work
17. (1) 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 and prorated dose limits.
(2) For the purpose of this section, a prorated effective dose limit is the product obtained by multiplying the applicable dose limit prescribed by section 13 or 15 by the ratio of the number of months remaining in the dosimetry period to the total number of months in the dosimetry period.
(3) If an equivalent dose that exceeds the applicable equivalent dose limit prescribed by section 14 or 15 is received by or committed to a person and the Commission or a designated officer authorized under paragraph 37(2)(h) of the Act authorizes the return to work of that person, the equivalent dose limit for the dosimetry period is the sum of the equivalent dose limit that was exceeded and the equivalent dose that was received by and committed to the person up to the time that the person was required to leave work in accordance with paragraph 16(b).
Application for Licence to Operate
18. 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.
