Radiation (Control of Irradiating Apparatus) Regulations

[CAP. 303

B 13

[Subsidiary]

(2) Any person who contravenes any of the provisions of subregulation (1) shall be guilty of an offence and be liable on conviction to a fine of $5,000. (L.N. 97 of 1970)

19. Marking of protective housing of X-ray tubes

(1) The protective housing of all X-ray tubes shall be indelibly marked in such a way as to show readily the equivalent lead thickness of the protective housing for the maximum voltage for which the housing is designed to be used.

(2) If the thickness of the protective material incorporated in the protective housing is not uniform over the entire surface thereof, the marking showing the equivalent thickness of lead may be replaced by a marking showing the farthest distance in any direction, measured from the target of the X-ray tube, at which all radiation, other than the useful beam, is reduced to an exposure rate of 25 microcoulombs per kilogram per hour if the enclosed X-ray tube is energized at its highest rated continuous milliamperage and maximum voltage. (L.N. 410 of 1982)

(3) Any licensee who operates, or causes to be operated, any X-ray tube which is not enclosed in a protective housing marked in accordance with the provisions of subregulation (1) or (2) shall be guilty of an offence and be liable on conviction to a fine of $5,000. (L.N. 97 of 1970)

20. Restriction on radiation from television sets

Any person who manufactures, sells or possesses any television set which emits radiation at a rate exceeding 130 nanocoulombs per kilogram per hour measured at any readily accessible point on the surface of the apparatus shall be guilty of an offence and be liable on conviction to a fine of $5,000.

(L.N. 97 of 1970; L.N. 410 of 1982)

21. Determination of dose rate and quality of radiation

(1) No person shall use any irradiating apparatus for therapeutic purposes unless-

(a) the dose rate and the quality of the radiation emitted by the apparatus have been measured by a person approved by the Board for that purpose and using an ionometric or other method of measurement also approved by the Board;

(b) both the dose rate and the quality of the radiation from such apparatus are periodically so measured at such intervals as the Board may direct; and
