四种自制被动积分灵敏测氡仪(计)的性能比较

Comparison of Four Types of Passive and Integrated and Sensitive Radon Monitors

为了提高测氡方法的灵敏度 ,研究了驻极多功能快速测氡仪、灵敏型矿工氡个人剂量计、电源式多功能快速测氡仪、被动式PCMR - 1连续测氡仪等四种被动积分灵敏测氡仪 (计 ) ,除了灵敏型矿工个人氡剂量计仅能测量氡浓度外 ,其它三种既可测量氡浓度 ,又可测量氡析出率 .介绍了四种测氡仪 (计 )的测量原理、技术指标、质量保证体系和优缺点 .平行测量结果表明 :测平均氡浓度时 ,它们在 5 %误差范围内一致 ;测氡析出率时 ,它们在 1 0

In order to improve the sensitivity of radon measurement method,Fast and Multifunctional Radon Monitor with Electret,Sensitive Miner Radon Monitor,Fast and Multifunctional Radon Monitor with High Voltage and PCMR-1 Passive and Continuous Radon Monitor were developed.Except Sensitive Miner Radon Monitor suits for radon concentration measurement only,the others can be used to measure both radon concentration and radon flux rate.Their measurement principles,specifications,quality assurance system,advantages and disadvantages are introduced.The simultaneous measurement results indicate that the errors among them are less than 5% and 10%,respectively,for the average radon concentration measurement and for the average radon flux rate measurement.
