吸入含有氡、氢子体的空气会使人体肺组织受到电离辐射的照射。多年来人们对测定氡、氢子体浓度的方法进行了大量的研究,归纳起来可分为两类:(1)总α放射性测量法。滤膜采样后,用α探测装置测定Ra

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.
