【摘要】 标准氡室是第三代标准氡源,通过智能化的自控技术可实现按期望值进行自动补氡,并且在较长时间内保持氡体积活度的稳定。文章探讨了标准氡室氡体积活度的补氡模型和稳氡模型,以及确定相关参数的测定技术。通过对标准氡室氡体积活度的实验测量,验证了上述模型建立的氡室可取得较好实用效果。更多还原

【Abstract】 Standard radon chamber,the third age of standard radon sources,supplements radon automatically according to the value of expectation by intelligentized control technology,which can keep stable radon volume radioactivity in a long time.In this paper model of radon supplementation and model of radon stabilization of radon volume radioactivity are explored,and measurement technologies of correlation parameters are established.Through the experiments of radon volume radioactivity,the standard radon chamber established by this model is proved much productive.更多还原
