高寒地区放射性干沉降物采集方法比较

分析高寒地区放射性干沉降物采样方法,解决高寒地区寒季采样介质结冰难题。采用不同采样介质和采样方法,观察采样期间介质状态,并对分析结果进行比较。乙二醇和去离子水混合液采集法与其他几种方法相比较更适合寒季干沉降物采集,能够有效解决寒冷天气干沉降物采集过程去离子水介质结冰现象,成本较低。建议在高寒地区根据不同气象条件,采用不同浓度乙二醇和去离子水混合液采集法采集放射性沉降物样品。

To analyze the collection methods of radioactive dry fallout,and solve the problem of sampling medium freezing during cold season in high-cold areas.Different sampling medium and methods were used to observe the state of medium during the collection process,and compared the analysis results.Glycol and deionized water mixture collection method compared with several other methods is more suitable for dry fallout sampling,it can effectively solve the phenomenon of freezing when only use deionized water medium during dry fallout collection process,and with lower cost.It is suggested to collect radioactive dry fallout with different concentration of glycol and deionized water mixture according to different meteorological conditions in high-cold condition.
