A theoretical basis is described for long-term measurement of the activities of the alpha emitters in air by the track-etching technique. Inference of the other activities allows working levels to be derived. A set of absorber foils allows the differing response to alpha particles of different energies to be used to identify the relative abundance of the alpha emitters and the importance of diffusion to surfaces. The method is appropriate to measuring long-term exposures to radon atmospheres in homes or mines.
描述了一种利用径迹蚀刻技术长期测量空气中α发射体活度的理论基础。通过推断其他活度可以得出工作水平。一组吸收箔可利用对不同能量α粒子的不同响应来确定α发射体的相对丰度以及扩散到表面的重要性。该方法适用于测量家庭或矿井中氡气环境的长期暴露情况。
