Abstract

A method to decrease photons generated by Β particles by using a capillary tube in liquid scintillation α spectrometry is presented. Liquid scintillation counting of 241Am and 152Eu was performed with 200, 300, and 500μm inner diameter (i.d.) PFA tubes as the detection cell. It was observed that the Β component in the energy spectrum is located at the lower-energy region with a decreasing i.d. of the PFA tubes, and the α peak of 241Am was separated from the Β component.
