58Prescribed practice

#### 58 Prescribed practice (1) The holder of a facility licence for a controlled facility must ensure that the doses to which a person is exposed, inside or in connection with the facility, do not exceed the effective dose limits mentioned in regulation 59, and the equivalent dose limits mentioned in regulation 62. (3) The holder of a source licence for dealing with controlled apparatus or controlled material must ensure that the doses to which a person is exposed while the source in the apparatus or material is under the holder’s control do not exceed the effective dose limits mentioned in regulation 59, and the equivalent dose limits mentioned in regulation 62. (4) The holder of a licence must ensure that radiation protection and safety of the following relating to the licence are optimised in order to achieve the outcome mentioned in subregulation (4A): (a) controlled material; (b) controlled apparatus (other than apparatus prescribed by these regulations that produce harmful non‑ionizing radiation when energised); (c) a controlled facility. (4A) For subregulation (4), the outcome is that the following are as low as reasonably achievable after taking into account economic and societal factors: (a) the magnitude of individual doses; (b) the number of people who are exposed; (c) the likelihood of incurring exposures to radiation. (5) The optimisation of radiation protection and safety mentioned in subregulation (4) must be in accordance with source‑related dose constraints established in accordance with the Planned Exposure Code and agreed by the CEO. (6) For apparatus prescribed by these regulations that produce harmful non‑ionising radiation when energised, the holder of a licence must ensure that exposure to people is kept to the lowest level that can be achieved, consistent with best practice.
