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.
