Version of section 18 from 2006-03-22 to 2008-04-16:

  •  (1) Subject to subsection (2), 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;

    • (b) contained in a static eliminator that has been retained by the licensee for less than 15 months.

  • (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
