Urine gross alpha/beta bioassay method development using liquid scintillation counting techniques

In the case of a radiological or nuclear incident, valuable information could be obtained in a timely manner by using liquid scintillation counting (LSC) technique through fast screening of urine samples from potentially contaminated persons. This work describes the optimization of LSC parameters on PerkinElmer (PE) Tri-Carb and Quantulus GCT series instruments to develop a rapid method for screening urine in an emergency response situation.
