New Zealand Legislation: Regulations
Regulations are laws made under Acts
(1) Every licensee shall ensure that if he, or any other person acting under the instruction or supervision of the licensee, uses a radioactive material or an irradiating apparatus under conditions in which either he or any such other person could receive in any period of 1 year, by absorption of radiation from sources outside the body, a dose equivalent exceeding 0.3 of the reference dose equivalent, any radiation dose received by either of them while engaged in the use of that radioactive material or that irradiating apparatus shall be continuously measured by means of a dosemeter of a type approved by the Director-General.
(2) Without limiting subclause (1) of this regulation, every licensee shall, if so required by the Director-General, cause radiation doses received by himself, or by specified persons working under his instructions or supervision with or in the neighbourhood of any source of radiation, or by persons performing specified work under his instructions or supervision, to be measured at such intervals as may be specified, by means of a dosemeter of a type approved by the Director-General.
(3) Every licensee shall, if so required by the Director-General, ensure that a radiation measuring instrument of a type approved by the Director-General is provided, and used to measure radiation dose rates as often as may be necessary to allow work to be planned so as to satisfy the requirements of subclauses (2) and (3) of regulation 18 of these regulations.
(4) Every licensee using unsealed radioactive material, or under whose instructions or supervision any other person uses such material, under conditions in which he or that other person could receive, by inhalation or ingestion of radioactive substances contained in such material, an intake during any period of 1 year that would lead to a dose equivalent commitment exceeding 0.3 of the reference dose equivalent shall ensure that an instrument of a type approved by the Director-General is provided and used to make appropriate measurements of levels of radioactive contamination as often as may be necessary to allow work to be planned and carried out so as to satisfy the requirements of subclauses (2) and (3) of regulation 18 of these regulations.
(5) Without limiting subclause (4) of this regulation, every licensee shall, if so required by the Director-General, ensure that an instrument is provided and used as described in the said subclause (4).
(6) Subclause (4) of this regulation shall not apply when the radioactive contamination that would be required to be measured is of a type for the measurement of which no instrument is reasonably obtainable.
(7) Every person who enters a controlled area shall, before he leaves that area, use the instrument (if any) made available pursuant to subclause (4) or subclause (5) of this regulation for the purpose of detecting any contamination by a radioactive substance on his hands or other part of his body or his clothing, and shall reduce such contamination to an amount estimated by the licensee to satisfy the requirements of regulation 18 of these regulations.
