Studies of background sources in liquid scintillation counting

Abstract

In these studies it has been shown that there are two main segments of background measured in a liquid-scintillation counter. One segment is unquenchable and is the result of background events which occur outside of the scintillation solution. The other segment is quenchable and is the result of interactions of cosmic rays, natural radioactivity and radioactive sources in the vicinity of the counter with liquid-scintillator solution.
