Abstract

Several calibration settings of diffusion barrier charcoal canister (DBCC) detectors for measuring radon concentration in air were studied. A set of functions and graphs were developed for relations between radon concentration in air and adsorbed activity in DBCC, when calibrated in small chambers. Both the integration time for 10% of DBCC of a batch, and the radon adsorption coefficient for the activated charcoal used in these detectors, were determined. Thus, a semi-empirical expression for detector calibration was applied.

摘要

研究了用于测量空气中氡浓度的扩散阻挡炭罐（DBCC）探测器的几种校准设置。当在小室内校准时，针对空气中的氡浓度与DBCC中的吸附活度之间的关系，开发了一组函数和图表。确定了一批DBCC中10%的积分时间以及这些探测器中使用的活性炭的氡吸附系数。因此，应用了探测器校准的半经验表达式。
