Nature of problem:This program computes the counting efficiency of a beta-gamma ray emitter as a function of the figure of merit in liquid scintillators. | ||

Solution method:The beta spectra are calculated from the Fermi theory of beta decayy, taking into account shape factors. The gamma-ray interaction with the scintillator is simulated by means of a Monte Carlo procedure, in order to obtain the gamma ray interaction probability and the spectrum of Compton and photoelectric electrons. The partial counting efficiency for beta gamma-ray coincidence, beta internal conversion coincidence and single beta-ray are computed to obtain the total counting efficiency. | ||

Restrictions:The counting efficiency is valid for spectrometers with two photo- multipliers working in coincidence. Pair production is not considered in the Monte Carlo code; hence, results for gamma-rays with energy superior to 2 MeV must be carefully considered. The cross sections for gamma-ray interaction correspond to a toluene based scintillator. For other scintillators, the corresponding cross section has to be modified. | ||

Running time:The test requires 147 s of cpu time for the IBM 3090/150 computer, including compilation and linking. |
