【摘要】 航空γ能谱测量方法是核辐射区域本地调查,区域环境中核辐射污染调查和评价的有效方法。文中不同于以往的利用航空γ能谱测量数据换算地面(1 m高)空气吸收剂量率的方法,而是运用大地-大气氡交换理论模型及氡的析出率理论,预测区域空气中氡浓度,并可计算出区域氡地质潜势。计算结果表明方法快速、高效,具有较好的实用价值。更多还原

【Abstract】 It is a very effective method of the airborne Gamma-ray spectrometry survey,which is extensively used in local environment pollute investigation.This paper used a new method of theory model of earth-air radon transportation and the formula of radon exhalation rate to dope out the atmosphere radon consistency and calculate the area geological potential,which is different from the tradition method of converse the airborne Gamma-ray spectrometry data into the absorbent dose rate on earth(1m above).The result shows that it has a great practice value by quickly determined.更多还原
