Abstract

The detection and measurement of transuranic activity in ambient air by counting alpha particles is confounded due to the presence of short-lived alpha-emitting isotopes due to radon and thoron. This paper describes an algorithm intended for use in a gross alpha-based continuous air monitor. The algorithm is capable of generating the variation of gross alpha count rate with time from air filter samples using in situ–measured radon progeny data. The required input of atom concentration can be obtained from a simple experimental technique, which is discussed here.

基于总阿尔法的连续空气监测器：数学建模，测量和解释

摘要

由于存在ra和，由于存在短命的发射α的同位素，因此通过计数α颗粒来检测和测量环境空气中的超铀酸活性是令人困惑的。本文介绍了一种算法，该算法旨在用于基于Alpha的连续空气监测仪中。该算法能够使用原位测量的ra子代数据从空气滤清器样品中产生总阿尔法计数率随时间的变化。所需的原子浓度输入可以通过一种简单的实验技术获得，在此进行讨论。
