RADIATION PROTECTION AND CONTROL (IONISING RADIATION) REGULATIONS 2015 (NO 203 OF 2015) - REG 81

81—Person carrying out site radiography using apparatus etc to wear chirper and have radiation survey meter

        (1)         A person must not carry out, or assist in the carrying out, of site radiography using apparatus unless—

            (a)         the person is wearing or has affixed to his or her person a device of a kind specified in subregulation (2)

; and

            (b)         the person has a radiation survey meter of a kind specified in subregulation (3)

immediately available for his or her use.

        (2)         The device referred to in subregulation (1)(a)

of this regulation (commonly known as a "chirper") must be a device that—

            (a)         is capable of detecting the type and energy of radiation being used; and

            (b)         emits an audible signal upon detecting radiation, the rate at which the audible signal is produced being proportional to the equivalent dose rate incident upon the device; and

            (c)         is of a kind that has been approved by the Minister.

        (3)         The radiation survey meter referred to in subregulation (1)(b)

must be a device that—

            (a)         is designed to measure radiation of the type and energy emitted by the apparatus in use; and

            (b)         has a measurement range of equivalent dose rate from 10 microsievert per hour to at least 10 000 microsievert per hour; and

            (c)         continues to indicate, either visibly or audibly, when the radiation level exceeds the maximum of the measurement range being used; and

            (d)         indicates the measured quantity with a measurement uncertainty of no more than ± 30%, inclusive of uncertainty due to variations in response with energy over the range of energies of the radiation to be measured.

        (4)         An owner of apparatus used for site radiography must provide every person who uses apparatus of which he or she is the owner with the chirper and radiation survey meter of the kind required by subregulation (1)

.

        (5)         It is sufficient compliance with subregulation (1)

if the same radiation survey meter is available for use by the person carrying out the site radiography and the person assisting him or her.

        (6)         An owner of apparatus used for site radiography must, in respect of a radiation survey meter he or she provides under subregulation (4)

—

            (a)         calibrate the survey meter at intervals not exceeding 12 months; and

            (b)         cause the calibration of the survey meter to be carried out by a body or organisation approved by the Minister; and

            (c)         keep a record of each calibration, which may consist of calibration certificates issued by the body or organisation that performed the calibration.

        (7)         An owner of apparatus used for site radiography must in respect of a chirper he or she provides under subregulation (4)

—

            (a)         test the chirper at intervals not exceeding 3 months; and

            (b)         make or cause to be made records of each test so performed.

        (8)         The test referred to in subregulation (7)

must—

            (a)         test the response of the chirper to the type and energies of radiation used by the owner for the purposes of site radiography; and

            (b)         test the dependence of the chirp rate upon the equivalent dose rate received by the chirper; and

            (c)         be of a kind approved by the Minister.

        (9)         An owner of an apparatus used for site radiography must maintain in good order and condition the chirper and survey meter provided by him or her under this regulation.
