温湿度对矿石短期释氡与活性炭短期吸氡的影响研究

摘要

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 Ra-don 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 in-creasing 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 .%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。
