北京地区大气氡浓度日变化与气象要素影响分析

Analysis on the Diurnal Variation of Radon Concentration and the Influence of Meteorological Condition on It in Beijing

氡及其子体是人类所受天然辐射照射的重要来源,大气中氡浓度变化受到各气象要素的影响显著。本研究使用氡及氡子体连续测量装置,进行了为期两年的全时测量。依据团簇理论,对大气氡浓度日变化情况进行了气象要素影响分析。结果表明,各气象要素对大气氡浓度有明显影响。

Radon and its daughters are important sources of natural exposure to human beings.The variation of radon concentration in the atmosphere is significantly affected by variation of meteorological condition.We carried out a two-year full-time measurement using a continuous measurement device for radon and its daughters.Based on the cluster theory,the influence of meteorological condition therein is analyzed.This could be a reference for the study of radon and its daughters in the atmosphere.
