New Zealand Legislation: Regulations
Regulations are laws made under Acts
Schedule 1 |
(1) 1 becquerel is an activity of 1 transformation per second.
(2) For the purposes of these regulations, when the transformation of the atoms of a radionuclide gives rise to another radionuclide, the activity is measured by the rate of transformation of the first or “parent”
radionuclide only.
The groups of radionuclides referred to in paragraph (a) of regulation 4(1) of these regulations, and the corresponding activities are those set out in the following table:
