The amount of neptunium and plutonium formed during the event was estimated through radiochemical analysis of the uranium solution from within the tank.

Returning to NAMAS, A. Lally (MAFF, CVL, Weybridge) illustrated how accreditation had been obtained for an environmental radiochemical analysis laboratory.

Bioaccumulated metals or radioactive fission decay products are like chemical signatures: chemical and radiochemical analysis can be used to identify the origin of imported specimens, and for long-term radioecological monitoring of polluted areas.

Nuclear tests, including underground tests that vent into the atmosphere, produce fallout that not only indicates that a nuclear event has taken place, but, through radiochemical analysis of radionuclides in the fallout, characterize the technology and source of the device.
