low specific activity waste

LSA is not part of the IAEA’s proposed waste classification scheme; however it is used by some Member States to indicate radioactive waste with very low levels of radionuclides. Some Member States refer to this as very low level waste (VLLW), which is also not part of the IAEA’s proposed scheme.
