In the framework of the EMPIR research project Metrology for Radon, a facility was devised that provides stable and traceable atmospheres for the realization of radon activity concentration at a high metrological level. The facility is used to calibrate and test devices for measuring radon in the air. It enables precise long-term exposures in the range between 100 Bq/m and 1000 Bq/m. The radon activity concentrations are realized with uncertainties of about 1.0 % (k = 1).
在欧洲计量研究计划（EMPIR）“氡计量学”研究项目的框架内，设计了一种装置，该装置可提供稳定且可溯源的环境，以在高计量水平上实现氡活度浓度。该装置用于校准和测试空气中氡测量设备。它能够在100 Bq/m³至1000 Bq/m³的范围内进行精确的长期暴露。所实现的氡活度浓度的不确定度约为1.0%（k = 1）。
