Packaging and Transport of Nuclear Substances Regulations, 2015 — 3
Characterization 3 (1) The nuclear substance referred to in paragraph 2 (2)(o) must be characterized at the earliest possible time to determine the extent to which it is subject to these Regulations and the Nuclear Substances and Radiation Devices Regulations . Licensable quantity (2) For the purpose of this section, a licensable quantity of a nuclear substance is a quantity (a) in respect of which the activity exceeds the exemption quantity, as defined in section 1 of the Nuclear Substances and Radiation Devices Regulations ; or (b) in respect of which there is no exemption from licensing under sections 5 to 8.1 of those Regulations. Documentation of characterization (3) The person who performs the characterization must (a) keep a record documenting the detection of the radiation and the disposal of the nuclear substance for two years; (b) file an annual report with the Commission by April 30 that contains a summary of radiation detections for the calendar year before the date of the report; and (c) immediately notify the Commission if the source of the radioactivity in the load is determined to be a licensable quantity of a nuclear substance. Dose rate greater than 5 µSv/h and less than or equal to 25 µSv/h (4) If the measured dose rate at the time that the alarm is triggered is greater than 5 µSv/h and less than or equal to 25 µSv/h and there is no loss or dispersal of the nuclear substance during the transport, the consignor, the carrier and the consignee must (a) immediately make a preliminary report to the Commission indicating the alarm level, the details of the transport, information on the location and circumstances of the detected radiation and any action that they have taken or propose to take in respect of it; and (b) characterize the source of the radiation within 10 days after its detection and make a follow-up report (i) immediately, if the characterization of the source of the radioactivity in the load indicates that it is a licensable quantity of a nuclear substance, or (ii) within 21 days after the initial detection, if the nuclear substance in the load is determined not to be of a licensable quantity, with a summary of the radiation detection and the disposal of the substance and a confirmation that it is not of a licensable quantity. Dose rate greater than 25 µSv/h and less than or equal to 500 µSv/h (5) If the measured dose rate at the time that the alarm is triggered is greater than 25 µSv/h but less than or equal to 500 µSv/h and there is no loss or dispersal of the nuclear substance during the transport, the consignor, carrier and consignee must (a) immediately make a preliminary report to the Commission indicating the alarm level, the details of the transport, information on the location and circumstances of the detected radiation and any action that they have taken or propose to take in respect of it; (b) isolate the load, prevent dispersal of the nuclear substance and control access to it to ensure that persons are not exposed to effective doses that exceed the limits set out in section 13 of the Radiation Protection Regulations ; (c) have an expert in radiation protection assess the situation; and (d) report the results of the assessment to the Commission within 10 days after the detection and make a follow-up report (i) immediately, if the characterization of the source of the radioactivity in the load indicates that it is a licensable quantity of a nuclear substance, or (ii) within 21 days after the initial detection, if the nuclear substance in the load is determined not to be of a licensable quantity, with a summary of the radiation detection and the disposal of the substance and a confirmation that it is not of a licensable quantity.
