Note 1: The activity of a progeny nuclide included in secular equilibrium with a parent nuclide is dealt with in section 5. Parent nuclides and progeny nuclides are set out in Part 2 of this Schedule, and parent nuclides are also marked a in the table in this Part.

Note 2: A nuclide marked m or m' in the table indicates a metastable state of the nuclide, with the metastable state m' indicating a state of higher energy than the metastable state m.
