本文件描述了被动采样的radon-222集成测量技术。它给出了根据易于使用和低成本的被动采样测量确定空气中氡-222平均活度浓度的指示，以及传感器的使用条件。本文件涵盖了从几天到一年不等的时间内不间断采集的样本。该测量方法适用于氡活度浓度大于5 Bq/m3的空气样品。
This document describes radon-222 integrated measurement techniques with passive sampling. It gives indications for determining the average activity concentration of the radon-222 in the air from measurements based on easy-to-use and low-cost passive sampling, and the conditions of use for the sensors.This document covers samples taken without interruption over periods varying from a few days to one year.This measurement method is applicable to air samples with radon activity concentrations greater than 5 Bq/m3.
