Radionuclide name, symbol, isotope
Concentration for notification. Regulation 6 and Schedule 1 (Bq/g)
Quantity for notification. Regulation 6 and Schedule 1 (Bq)
Quantity for notification of occurrences. Regulation 30(1) (Bq)
Quantity for notification of occurrences. Regulation 30(3) (Bq)
Note 1
In the case of radionuclides not specified elsewhere in this Part, the quantities specified in this entry are to be used unless the Executive has approved some other quantity for that radionuclide.
Note 2
Nuclides carrying the suffix “+” or “sec” in the above Table represent parent nuclides in equilibrium with their correspondent daughter nuclides as listed in the following Table. In this case the concentrations and quantities given in the above Table refer to the parent nuclide alone, but already take account of the daughter nuclide(s) present.
List of nuclides in secular equilibrium as referred to in note 2 of this Schedule.
