Radon risk assessment is carried out by means of accurate measurements with active or passive instrumentation. All radon detectors must be calibrated and tested using a radon chamber containing a known concentration of radon produced by specific sources of (226)Ra. Some chambers can also be used to test the response of detectors as a function of environmental conditions. In this case, a calibration curve can be inferred with respect to change in one of the considered parameters. For this aim, a new radon chamber was designed and realised to perform calibration and to study the detector response in a large range of variation of the environmental parameters (pressure, 700-1100 mbar; temperature, 5-50°C; humidity, 10-90 %). The first experiments conducted to study the influence of environmental parameters on the detector response have shown flexibility and ease of use of the chamber.
氡风险评估是通过使用主动或被动仪器进行精确测量来开展的。所有氡探测器都必须使用一个氡室进行校准和测试，该氡室含有由特定（226）镭源产生的已知浓度的氡。一些氡室还可用于测试探测器作为环境条件函数的响应。在这种情况下，可以根据所考虑参数之一的变化推断出校准曲线。为此目的，设计并实现了一个新的氡室，以进行校准并研究探测器在大范围环境参数变化（压力，700 - 1100毫巴；温度，5 - 50°C；湿度，10 - 90%）下的响应。为研究环境参数对探测器响应的影响而进行的首次实验表明，该氡室具有灵活性且易于使用。
