Abstract

Quench correction in liquid scintillation counting has been investigated. A detailed comparison of the curve fitting routines compatible with a microcomputer has been made for the quench calibration curve and concludes that a cubic spline with natural end conditions is most suitable. The effect of colour/chemical quenching on the calibration curve and the choice of regions for dual and triple radionuclide counting is studied.

A new computer simulation of the LS counter has been created and proven to be a useful tool in LS counting. Modelling of the LSC has led to the invention of several novel quench correction techniques which are independent of colour and/or chemical quench for homogeneous solutions. A fully worked example of the use of one of the techniques (the SumDiff quench correction method) is presented. The successful application and modular design of the simulation has established a LS research program from which future discoveries are anticipated.
