ABSTRACT:
This invention is a technique to determine radioactivity of low energy beta emitters using liquid scintillator. Corrections for regression equations which represent the relationship between counting efficiency of a standard and counting rate of a sample make it possible to obtain the radioactivity of the low energy beta emitters. It is very difficult for the emitters to be measured with the conventional efficiency tracing technique.
