Description

The amount of natural potassium-40 in urine varies from sample to sample. Potassium-40 is a beta-emitter (1.314 MeV max) and can interfere in gross beta analysis for nuclides such as Strontium-90 and fission products. The method uses at Lawrence Livermore National laboratory for screening gross beta activity in urine are discussed. The Livermore method has proven to work well for screening large numbers of samples. Sample processing can be done in one to two days. Atomic absorption spectroscopy can also be used to confirm potassium readings when positive results do occur
