Radiation Protection Regulations

1 (1) The definitions in this subsection apply in these Regulations.

absorbed dose

absorbed dose means the quotient, in gray, obtained by dividing the energy absorbed through exposure to radiation by the mass of the body or part of the body that absorbs the radiation. (dose absorbée)

Act

Act means the Nuclear Safety and Control Act. (Loi)

balance of the pregnancy

balance of the pregnancy means the period from the moment a licensee is informed, in writing, of the pregnancy to the end of the pregnancy. (reste de la grossesse)

committed

committed means, in respect of a dose of radiation, received by an organ or tissue from a nuclear substance during the 50 years after the substance is taken into the body of a person 18 years old or older or during the period beginning at intake and ending at age 70, after it is taken into the body of a person less than 18 years old. (engagée)

dosimeter

dosimeter means a device for measuring a dose of radiation that is worn or carried by an individual. (dosimètre)

effective dose

effective dose means the sum of the products, in sievert, obtained by multiplying the equivalent dose of radiation received by and committed to each organ or tissue set out in column 1 of an item of Schedule 1 by the weighting factor set out in column 2 of that item. (dose efficace)

equivalent dose

equivalent dose means the product, in sievert, obtained by multiplying the absorbed dose of radiation of the type set out in column 1 of an item of Schedule 2 by the weighting factor set out in column 2 of that item. (dose équivalente)

exemption quantity

exemption quantity has the same meaning as in section 1 of the Nuclear Substances and Radiation Devices Regulations. (quantité d’exemption)

five-year dosimetry period

five-year dosimetry period means the period of five calendar years beginning on January 1 of the year following the year in which these Regulations come into force, and every period of five calendar years after that period. (période de dosimétrie de cinq ans)

licensed activity

licensed activity means an activity described in any of paragraphs 26(a) to (f) of the Act that a licence authorizes the licensee to carry on. (activité autorisée)

licensee

licensee means a person who is licensed to carry on an activity described in any of paragraphs 26(a) to (f) of the Act. (titulaire de permis)

one-year dosimetry period

one-year dosimetry period means the period of one calendar year beginning on January 1 of the year following the year in which these Regulations come into force, and every period of one calendar year after that period. (période de dosimétrie d’un an)

radon progeny

radon progeny means the following radioactive decay products of radon 222: bismuth 214, lead 214, polonium 214 and polonium 218. (produit de filiation du radon)

skin

skin means the layer of cells within the skin that are 7 mg/cm² below the surface. (peau)

worker

worker means a person who performs work that is referred to in a licence. (travailleur)

working level

working level means the concentration of radon progeny in l m³ of air that has a potential alpha energy of 2.08 × 10^-5 J. (unité alpha)

working level month

working level month means the exposure that results from the inhalation of air containing one working level for 170 hours. (unité alpha-mois)

(2) For the purpose of the definition dosimetry service in section 2 of the Act, a facility for the measurement and monitoring of doses of radiation received by or committed to nuclear energy workers who have a reasonable probability of receiving an effective dose greater than 5 mSv in a one-year dosimetry period is prescribed as a dosimetry service.

(3) For the purpose of the definition nuclear energy worker in section 2 of the Act, the prescribed limit for the general public is 1 mSv per calendar year.
