在PTB的氡参考室中，使用不同的α和γ光谱系统测量氡及其子体，并控制全套环境参数，例如温度、湿度、气压和气溶胶浓度。环境参数的测量和控制不仅对氡活度浓度刻度的质量至关重要，而且对所有氡子体活度浓度的测量和由此产生的平衡因子都是必不可少的。因此，适当地选择室的基本设计和构造、气候控制、气溶胶产生和空气清洁器，以提供稳定的条件和参数的宽变化。本文介绍了德国氡参考室在环境参数变化方面的主要优点。
In the radon reference chamber of the PTB, radon and its progenies are measured with different systems for α- and γ-spectrometry with the full set of environmental parameters, e.g. temperature, humidity, air pressure and aerosol concentration being controlled. Measurement and control of the environmental parameters is important not only for the quality of the calibration of radon activity concentration but also absolutely necessary for all measurements of activity concentrations of radon progenies and the resulting equilibrium factors. Therefore, the basic design and construction of the chamber, the climate control, the aerosol generation and the air cleaner are properly chosen to provide stable conditions and a wide variation of the parameters. The main advantages of the German radon reference chamber with respect to the variation of environmental parameters is given in this work.
