摘要为了保证氡及其衰变产物测量的高精度，BFS建立了一套质量保证管理体系。在实验室安装了一套校准室和容器，这些实验室后来被认证为德国校准服务（DKD）校准实验室，用于氡单位及其短寿命衰变产物的潜在α能量浓度。它可以追溯到联邦物理技术研究所（PTB）制定的国家标准，PTB同时也是德国的国家科学技术研究所和最高计量技术权威。该设备可以进行科学研究，并在50 Bq/m3和100 kBq/m3之间的范围内对测量量“空气中Rn-222的浓度”进行校准，还可以在2 MeV/cm 3之间的范围内对测量量“潜在α能量浓度”（PAEC）进行校准（3.2 E-7 J/m3）和4000 MeV/cm3 1（* 6.4 E-4 J/m3）。
Abstract In order to guarantee a high level of accuracy in all areas concerned with radon and radon decay products measurement the BfS has established a quality assurance management system. A set of calibration chambers and containers was installed in the laboratories which were subsequently accredited as a German Calibration Service (DKD) Calibration Laboratory for the units of radon and the potential alpha energy concentration of its short-lived decay products. It is traced back to the national standard established at the Physikalisch-Technische Bundesanstalt (PTB), which is at the same time the national institute for science and technology, and the highest technical authority for metrology in Germany. The equipment makes possible scientific investigations as well as calibrations for the measuring quantity “concentration of Rn-222 in air” in the range between 50 Bq/m3 and 100 kBq/m3 and also for the measuring quantity “potential alpha-energy concentration” (PAEC) in the range between 2 MeV/cm3 (3.2 E-7 J/m3) and 4000 MeV/cm31 (*6 .4 E-4 J/m3).
