conditional clearance level

conditional clearance level means an activity concentration that does not result in an effective dose

exemption quantity

exemption quantity means any of the following:

  • (a) in respect of a radioactive nuclear substance set out in column 1 of Schedule 1,

    • (i) if the radioactive nuclear substance is uniformly distributed in material and not in bulk quantity, the corresponding activity concentration set out in column 2, or

    • (ii) the corresponding activity set out in column 3;

  • (b) in respect of a radioactive nuclear substance that is not set out in column 1 of Schedule 1,

    • (i) if the atomic number of the substance is equal to or less than 81,

      • (A) 10 Bq/g if the radioactive nuclear substance is uniformly distributed in material and not in bulk quantity, or

      • (B) 10,000 Bq,

    • (ii) if the atomic number of the substance is greater than 81 and the substance, or its short-lived radioactive progeny, does not emit alpha radiation,

      • (A) 10 Bq/g if the radioactive nuclear substance is uniformly distributed in material and not in bulk quantity, or

      • (B) 10,000 Bq, or

    • (iii) if the atomic number of the substance is greater than 81 and the substance, or its short-lived radioactive progeny, emits alpha radiation,

      • (A) 1 Bq/g if the radioactive nuclear substance is uniformly distributed in material and not in bulk quantity, or

      • (B) 1,000 Bq; or

  • (c) in respect of more than one radioactive nuclear substance,

    • (i) if the radioactive nuclear substances are uniformly distributed in material and not in bulk quantity, the quotient obtained by dividing the total activity concentration by the sum of quotients obtained by dividing the activity concentration of each radioactive nuclear substance by its corresponding exemption quantity as referred to in paragraph (a) or (b), or

    • (ii) the quotient obtained by dividing the total activity by the corresponding sum of quotients obtained by dividing the activity of each radioactive nuclear substance by its corresponding exemption quantity as referred to in paragraph (a) or (b). (quantité d’exemption)

exposure device

exposure device means a radiation device that is designed for carrying out gamma radiography, and includes any accessory to the device such as a sealed source assembly, a drive mechanism, a sealed source assembly guide tube and an exposure head. (appareil d’exposition)

IAEA Safety Standard RS-G-1.7

IAEA Safety Standard RS-G-1.7 means the IAEA Safety Standards, Safety Guide No. RS-G-1.7 — Application of the Concepts of Exclusion, Exemption and Clearance, 2004 Edition published by the International Atomic Energy Agency. (Norme de sûreté RS-G-1.7 de l’AIEA)

licensed activity

licensed activity means an activity described in any of paragraphs 26(a) to (c) of the Act that a licence authorizes the licensee to carry on in relation to a nuclear substance or a radiation device. (activité autorisée)

licensee

natural uranium means uranium that contains uranium 235 in a concentration that is normally found in nature. (uranium naturel)

nuclear criticality

nuclear criticality means a self-sustaining chain reaction of nuclear fission. (criticité nucléaire)

operate

operate includes, in respect of an exposure device, coupling the drive mechanism to the exposure device, uncoupling the drive mechanism from the exposure device, locking or unlocking the exposure device, and all activities involving the device that take place while the sealed source assembly is not locked inside the device in the fully shielded position. (faire fonctionner)

prescribed equipment

radiation device

radiation device means

  • (a) a device that contains more than the exemption quantity of a nuclear substance and that enables the nuclear substance to be used for its radiation properties; and

  • (b) a device that contains a radium luminous compound. (appareil à rayonnement)

radiation survey meter

radiation survey meter means an instrument that is capable of measuring radiation dose rates. (radiamètre)

sealed source

sealed source means a radioactive nuclear substance in a sealed capsule or in a cover to which the substance is bonded, where the capsule or cover is strong enough to prevent contact with or the dispersion of the substance under the conditions for which the capsule or cover is designed.
