absorbed dose means the energy absorbed per unit mass by matter from ionizing radiation that impinges upon it.
Note: See the Planned Exposure Code.
Act means the Australian Radiation Protection and Nuclear Safety Act 1998.
action level means an intervention level applied to exposure to radiation.
activity concentration value steps: the activity concentration value steps for a waste package are the following steps:
 (a) first, divide the activity of each nuclide in the waste package by the mass of the waste package;
 (b) secondly, divide the result of paragraph (a) for each nuclide by the activity concentration value set out in Part 1 of Schedule 1 for the nuclide;
 (c) thirdly, if there is more than one nuclide in the waste package, total the result of paragraph (b) for each nuclide.
Note: Section 5 affects how the activity of a parent nuclide mentioned in Part 2 of Schedule 1 (or marked a in Part 1 of Schedule 1) is worked out, by providing for inclusion of the activity of certain progeny nuclides that are included in secular equilibrium with the parent nuclide.
activity value division steps: the activity value division steps for sources or controlled materials are the following steps:
 (a) first, divide the activity of each nuclide in the sources or controlled materials by the activity value set out in Part 1 of Schedule 1 for the nuclide;
 (b) secondly, if there is more than one nuclide in the sources or controlled materials, total the result of paragraph (a) for each nuclide.
Note: Section 5 affects how the activity of a parent nuclide mentioned in Part 2 of Schedule 1 (or marked a in Part 1 of Schedule 1) is worked out, by providing for inclusion of the activity of certain progeny nuclides that are included in secular equilibrium with the parent nuclide.
