【摘要】 <正> 国内现行水氡测试方法主要由“水样脱气”与“气氡检测”两个基本环节组成。人们已认识到温度对脱气过程的影响是水氡测试过程中的主要影响因素之一。由于现行方法(包括室内真空法与连续自记法)脱气过程的物理化学状态均处于非平衡态,因而这种温度影响无法定量修正。为了解决这一问题,有人建议在测试过程中采用恒温措施,但根据我国水氡网点布设的现状,多数水点或者条件不具备,或者效果欠佳。此外,在连续自动更多还原

【Abstract】 In this paper, the single parameter balance method for water Radon measurements is proposed in accordance with phase balance principle as there are some problems in the methods currently used for Radon measurements. Described, in detail in the paper are the basic principle of this method, the basic operational steps in room reasurements of Radon, automatic Radon measurements and on-spot measurements of Radon, experimental results, and the main advantages as well.更多还原
