103 Kinds of incidents that are nuclear safety incidents
(1) For the purposes of subparagraph 21(2)(b)(iii) of the Act, the following kinds of incidents, that relate to nuclear safety and occur in relation to the conduct of a regulated activity, are prescribed:
(a) an uncontrolled emission, escape, spillage or leakage of:
(i) NNP material; or
(ii) NNP equipment or plant;
(b) an uncontrolled emission, escape, spillage or leakage of ionising radiation that results in a significant increase in the magnitude of individual doses;
(c) an uncontrolled exposure to harmful non‑ionising radiation:
(i) from equipment or plant described in section 12 of this instrument; and
(ii) that results in an exposure limit specified in subsection (2) of this section being exceeded;
(d) a theft or loss of NNP material or NNP equipment or plant;
(e) damage to a package (however described) that contains NNP material or NNP equipment or plant;
(f) a near miss that could have resulted in any of the following:
(i) a significant increase in the magnitude of individual doses of ionising radiation;
(ii) an applicable dose limit under section 72 or 74 for a person being exceeded;
(iii) an exposure limit, specified in subsection (2), being exceeded in relation to harmful non‑ionising radiation from equipment or plant described in section 12.
(2) For the purposes of subparagraphs (1)(c)(ii) and (1)(f)(iii), the following, to the extent they relate to naval nuclear propulsion, are specified as exposure limits:
(a) the reference levels mentioned in the ICNIRP Guidelines For Limiting Exposure To Time‑Varying Electric And Magnetic Fields (1 Hz—100 kHz), published by the International Commission on Non‑Ionizing Radiation Protection, as existing on 4 April 2025;
(b) the maximum permissible exposure limits mentioned in AS/NZS IEC 60825.1:2014;
(c) the exposure limits mentioned in AS/NZS IEC 62471:2011;
(d) the exposure limits mentioned in the ICNIRP Guidelines On Limits Of Exposure To Static Magnetic Fields, published by the International Commission on Non‑Ionizing Radiation Protection, as existing on 4 April 2025;
(e) the exposure limits mentioned in the ICNIRP Guidelines for Limiting Exposure to Electromagnetic Fields (100 kHz to 300 GHz), published by the International Commission on Non‑Ionizing Radiation Protection, as existing on 4 April 2025.
