Nature of problem:
In liquid scintillation counting it is often required to know the counting efficiency. A model of the basic interactions allows one to calculate the detection efficiency for beta emitters as a function of the figure of merit. The program is applicable to single and complex beta emitters.
The beta spectrum is calculated from the Fermi theory of beta decay. Corrections by a shape factor have been considered. The total detection probability is obtained by dividing the spectrum into bands, calculating the detection probability for each band summing.
The program is designed to be used in the counting efficiency calculation of negatron and positron emitters. The counting efficiency computation for electron capture nuclides is not considered. The present version of the program is restricted to spectra with 800 points. This value may be increased by increasing the storage of the corresponding arrays.
The test requires about 9 s of UNIVAC 1100/80 cpu time.
