RADIATION (CONTROL OF IRRADIATING APPARATUS) REGULATIONS - REGULATION 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

   (c)  a record of all such measurements is kept by the licensee and is open
        to inspection by any person authorized by the Board for that purpose.

(2) No person shall use a radiation dosemeter or a radiation dose-rate meter
for any determination made in accordance with subregulation (1), unless it is
independent of, or corrected for, the quality of radiation within the range
for which it is designed or used, and is provided with suitable arrangements
for checking its ability to reproduce its readings.

(3) Any person who contravenes any of the provisions of subregulation (1) or
(2) shall be guilty of an offence and be liable on conviction to a fine of
$15000. (L.N. 97 of 1970; L.N. 225 of 1990)
