新型连续测氡仪温湿度效应快速修正

为快速获得测氡仪温湿度修正系数,提出一种快速修正连续测氡仪温湿度效应的方法。该方法是将绝对湿度和对应的温湿度修正系数进行近似线性处理,并将线性拟合函数植入新型连续测氡仪中。实验结果表明,应用该快速修正方法在绝对湿度20 g/m3以下,其测氡结果与标准参考值的相对偏差在5%以内。

Rapid Revising for Temperature and Humidity Effects of Novel Continuous Radon Monitors

In order to rapidly acquire the correction factors of the temperature and humidity of radon monitors, a method to rapidly revise temperature and humidity effects of continuous radon monitors should be proposed.Firstly, approximate linearization of the moisture ratio of completely saturated vapor at certain temperature and absolute humidity should be made with the correction factors of corresponding temperature and humidity.And then the linear fitting function should be inserted into a novel continuous radon monitor, so the correction factors of temperature and humidity can be obtained by several sets of data.The results of the experiment indicate that when this method is applied under an absolute humidity of 20 g/m3, the relative deviation between the results of radon measurements and reference value is no more than 5%.
