在这项工作中，氡校准室的设计和建造在环境污染实验室的巴士拉大学。室内容积为125升，并包含一个标准氡源（226 Ra）和氡分布风扇。在实验过程中，室内的压力和温度保持恒定。用该设计获得了不同类型的标定数据，用25 cm × 7 cm圆柱形罐对CR 39进行了标定，标定因子为0.2279±0.022Tr/cm ~ 2·d/Bq/m ~ 3。而11 cm x 7 cm的校准因子为0.3420±0.0459 Tr/cm 2。采用6cm × 7 cm杯法，室内校正因子为0.1888±0.0433Tr/cm ~ 2.d/Bq/m ~ 3。
In this work a radon calibration chamber was designed and build in the environmental pollution laboratoryuniversity of Basra. The chamber a volume is 125l and contains a standard radon source (226Ra) and radon distribute fan. The pressure and temperature inside the chamber are kept constant during the experiment. Different types of calibration data wereachieved by using this design.The calibration factor of CR39 used in cylindrical can 25cm x 7 cm was found to be 0.2279±0.022Tr/cm2.d/Bq/m3. While, calibration factor for 11 cm x 7 cm was 0.3420±0.0459 Tr/cm2. d/Bq/m3 and the indoor calibration factor using cup technique 6 cm x 7 cm was 0.1888±0.0433Tr/cm2.d/Bq/m3.
