地震前氡衰变引起大气温度与湿度异常问题讨论

强地震前地震区域会出现卫星热红外增温异常现象,S A Pulinets提出了一种新的解释,认为是震前地表大量析出的222Rn衰变产生的高能α粒子使得空气电离,这些离子很容易吸附水蒸气分子,导致大气中潜热的释放,使得空气温度、湿度发生显著变化.本文分析了高能α粒子对空气辐射电离后的主要物理、化学作用,估算了放热和吸附水蒸气分子数量的极大值,结果表明空气温度、湿度的变化是微不足道的.由此认为,地震前出现的温度升高、湿度下降的现象可能与氡浓度变化无关.

On the abnormities of air temperature and humidity by radon decay before strong earthquakes

Satellite thermal infrared images indicated the presence of positive thermal anomalies before strong earthquakes. Pulinets S A presented a new interpretation that the earth's surface precipitated massive ~(222)Rn before earthquakes, and the high-energy α particles emitted by ~(222)Rn decay led to air ionization. These ions can easily adsorb water vapor molecules, which then led to the release of latent heat in the atmosphere, making air temperature and humidity change significantly. This paper analyzes the main physical and chemical effects of high-energy α particles after air ionization and estimates the maximum values of the released heat and absorbed water vapor molecules. The result shows that the changes in air temperature and humidity are negligible. Therefore, the phenomena of temperature rise and humidity drop may have nothing to do with the variation in radon concentration before strong earthquakes.
