摘　　要：空气湿度变化环境下的氡浓度连续测量准确性是困扰多年的问题。研究提出了一种改进的ZtiS闪烁室氡连续测量方法并研制出原型测量装置,设计制作了可调节湿度和稳定氡浓度的小型氡室,对原型测量装置进行了湿度效应测试。测试结果表明,在空气相对湿度为14%〜96%时,原型测量装置的氡计数测量误差小于10%,解决了较宽空气湿度变化环境特别是高湿度环境下的氡浓度连续测量准确性问题。There is a problem plaguing continuous monitoring of radon concentration in underground uranium mines for many years that the accuracy of continuous measurement of radon concentration under the environment of changing air humidity is difficult to be achieved.An improved ZnS scintillation chamber radon continuous measurement method has been proposed and a prototype measurement device has been developed.A radon chamber with adjustable humidity and stable radon concentration has been designed and manufactured.The prototype device was tested for humidity effects.It indicates that the radon count measurement error of the prototype measurement device is less than 10%in the range of 14%to 96%relative air humidity,which solves the problem of continuous measurement of radon concentration in a wide range of air humidity,especially in high humidity.
