空氣中氡濃度時間變化規律探討Although thoron is one of isotopes of radon, and the characteristics of thoron and thoron progenies are similar to those of radon and radon progenies, because the half life of thoron is shorter ( 55. 6s ), the concentrations of thoron and thoron daughters in environment are lower, people usually think that the effective dose from thoron and its progenies can be eliminated, and the measurements of thoron progenies concentrations are difficulty, a little research work on the dose evaluation of thoron and thoron progenies in environment has been done
雖然(氣土)是氡的同位素,它及其子體的特性也與氡及其子體的相似,但由於(氣土)的半衰期短( 55 6s ) ,環境中(氣土)濃度較低, (氣土)及其子體濃度的測量較難,人們一般認為(氣土)及其子體所致劑量可以忽略,所以對環境中(氣土)及其子體劑量評價研究很少。The authors used the theoretical model to calculate the radon concentration of air at a certain residential area of linchuan city, jianxi province, which has been preliminarily proved to the effective
