Manual Liquid Scintillation Counting System
Introduction
Liquid scintillation counter (LSC) is a high efficiency laboratory counting system. This system is used for the detection and quantification of radiations even with very low penetrating power such as a and b particles. This is a PC based manually operated system for detecting even small amounts of beta and alpha radioactivity. Usage of excellent quality high efficiency matched pair of photo multiplier tubes, precision fast and slow preamplifiers, high speed analog electronics design, USB based spectroscopy quality MCA, rugged manually operated sample chamber with lead shield allow the system to offer high efficiency even for low energy beta emitters such as tritium and also a very low background.
