Abstract

A computer program is presented for calculating air concentrations of the short lived progenies of radon and thoron by use of either total alpha counts technique or alpha-particle spectrometry. The program is written in BASIC language. A TRS-80 model I microcomputer has been used in the calculation. It takes about 40 seconds to output the concentrations of radon and thoron daughters in air and the accuracies in the measurements.
