RADIATION PROTECTION AND CONTROL (IONISING RADIATION) REGULATIONS 2000 - REG 79

79—Registered owner of X-ray analysis apparatus to make available radiation monitoring instrument for radiation surveys

        (1)         The registered owner of X-ray analysis apparatus must have or make available a radiation monitoring instrument that complies with subregulation (2) for the purpose of carrying out the radiation surveys required by regulation 73.

        (2)         A radiation monitoring instrument must—

            (a)         be accurate to within ±50% for the energy range of the primary beam radiation produced over the operating kilovoltage range of the X-ray analysis apparatus for which it is to be used; and

            (b)         have a sensitivity which gives a positive response at an equivalent dose rate of at least 10 microsievert per hour, measured in a field of radiation uniform over the sensitive volume of the detector with the energy range specified in paragraph (a); and

            (c)         have a meter or similar read-out device that—

                  (i)         is calibrated in units of exposure rate, equivalent dose rate or absorbed dose rate; or

                  (ii)         is calibrated in arbitrary units, but has indicated on the instrument the appropriate method of conversion from those units to exposure rate, equivalent dose rate or absorbed dose rate for a radiation field uniform over the sensitive volume of the detector.
