• 18. (1) Every licensee who possesses, uses or produces either a sealed source containing 50 MBq or more of a nuclear substance or a nuclear substance as shielding shall, at the following times, conduct leak tests on the sealed source or shielding using instruments and procedures that enable the licensee to detect a leakage of 200 Bq or less of the nuclear substance:

  • (a) where the sealed source or shielding is used after being stored for 12 or more consecutive months, immediately before using it;

  • (b) where the sealed source or shielding is being stored, every 24 months;

  • (c) exempted under section 5, 6, 8 or 8.1; or

  • (d) used or stored underwater in a nuclear facility that is equipped with a device capable of detecting water-borne contamination of 200 Bq or less of a nuclear substance.

• (3) Where a licensee, in the course of conducting a leak test on a sealed source or on shielding, detects the leakage of 200 Bq or more of a nuclear substance, the licensee shall

  • (a) discontinue using the sealed source or shielding;

  • (b) discontinue using the radiation device in which the sealed source or shielding is located or may have been located;

  • (c) take measures to limit the spread of radioactive contamination from the sealed source or shielding; and
