15 What are NNP material and NNP equipment or plant?

(1) NNP material (short for naval nuclear propulsion material) means any natural or artificial material (whether in solid or liquid form, or in the form of a gas or vapour) that: (a) emits ionising radiation spontaneously; and (b) is from, or for use on, an AUKUS submarine. (2) NNP equipment or plant (short for naval nuclear propulsion equipment or plant) means any equipment or plant from, or for use on, an AUKUS submarine, that: (a) produces ionising radiation when energised or that would, if assembled or repaired, be capable of producing ionising radiation when energised; or (b) produces ionising radiation because it contains radioactive material; or (c) both: (i) produces harmful non‑ionising radiation when energised; and (ii) is prescribed by the regulations. (3) Ionising radiation is electromagnetic or particulate radiation capable of producing ions directly or indirectly, but does not include electromagnetic radiation of a wavelength greater than 100 nanometres. (4) Non‑ionising radiation is electromagnetic radiation of a wavelength greater than 100 nanometres.
