Radiation (Control of Irradiating Apparatus) Regulations
[1989 Ed.
[Subsidiary]
PART VI
MATERIAL PROTECTION AND SAFE PRACTICE
17. Material protection in case of static irradiating apparatus person
(1) No licensee shall cause or permit any irradiating apparatus to be used continuously in any room unless the floors, ceilings, walls and observation windows thereof are so constructed that nowhere outside the room does the radiation dose rate, averaged over any one minute, exceed 7.5 micrograys per hour: (L.N. 410 of 1982)
Provided that the provisions of this subregulation shall not apply to any floor, ceiling, wall or observation window so sited that the space immediately outside thereof is not capable of habitual occupation by any human being.
(2) All protective material, other than sheet lead, shall be indelibly marked in such a way as to show readily its equivalent thickness of lead, and protective materials which depend upon substances other than lead for their protective properties shall in addition have marked thereon the constant electrical potential used for the generation of X-rays under the conditions at which the equivalence applies.
(3) All protective glass, including lead glass or lead barium glass, or protective liquid observation windows, shall be clearly and indelibly marked in such a way as to show readily its equivalent thickness of lead.
(4) No licensee shall use any protective material, other than sheet lead, which is not marked in accordance with the provisions of subregulation (2) or (3).
(5) Nothing in this regulation shall be construed to prevent the temporary removal from the address stated in the licence relating thereto of any portable or mobile irradiating apparatus incidental to its operation as such.
(6) Any licensee who contravenes any of the provisions of subregulation (1) or (4) shall be guilty of an offence and be liable on conviction to a fine of $5,000. (L.N.97 of 1970)
$15,000
18. Filtration of useful beam from X-ray machine used for fluoroscopy
(1) No person shall use for fluoroscopy of any part of the human body any X-ray machine unless the total filtration of the useful beam from such machine corresponds to not less than 2 mm thickness of aluminium, or its equivalent where other materials are used, as determined at the maximum voltage.
