温湿度对矿石短期释氡与活性炭短期吸氡的影响研究

The Effect of Temperature and Humidity on Uranium ore Release Radon and Activated Charcoal Adsorption in Short-Tern

为研究短时间下温湿度对矿石短期释氡与活性炭短期吸氡的影响,在温湿度恒定条件下,通过γ能谱仪测量温湿度变化下矿石释氡与薄层活性炭吸氡计数得出:(1)湿度不变时,温度升高矿石释氡与薄层活性炭吸氡的能力提升;(2)温度恒定时,矿石释氡能力随相对湿度的增加而增大,薄层活性炭吸附氡的能力随相对湿度的增加而降低。研究结果得到短时间活性炭吸附氡能力与环境因素的关系,填补了这一方面的研究空白。

To investigate the effect of Radon released from uranium ore and activated carbon absorb Radon with the temperature and humidity change in short time,by using gamma spectrometer to measure the counts of Radon released from uranium ore and absorbed by activated carbon when the temperature and humidity changed,it can conclude that：（ 1） The ability of Radon released from ore and absorbed by activated carbon is rising with the temperature is increased,while the humidity is constant;（ 2） The counts of Radon released from ore are increasing when the temperature is invariable when the humidity is increased,while the thin layer of activated carbon is contrary to it. The results make clear the relation between the ability of activated carbon to assimilate Radon and environment,which fill in a blank in activated carbon.
