Nuclear Radiation Measure Apply In The Ground Exploration

With the development of the city progress. People more and more regard of element and chemistry substance in relation to environment and health. Therein, soil is regarded the best and reliable element and chemistry storage. During city environment and estimate. people estimate and restrict superscale during soil contamination by environment capacity. However, people mainly consider static index by environment capacity. Lacking consider element and compound move and transform. much less consider opening circle problem during soil toward city zoology system of soil temporarily storage. Geogas during city environment often or occasionally deflate through city the earth's surface medium, let area or part gas concentration rise or produce abnormity. Even happening citizen poison or geogas explode, influence environment safety and citizen health.Due to people's living level enhancing, people desire more and more high to environment condition. Some radiation substance influence dwelling environment bring people's hurt, for example Rn andγ. many of years often happing geogas event, let people to research new object through city environment geogas and release rule. with regard to research geogas fewness to city environment, for population density city, people often change ground structure, let matter influence and change during soil geogas release. Geogas easily release on soft ground, often bring abnormity.This thesis exemplify Xiao Wan He radiation explore, research to measure data, calculate radiation quantity whether it accord with people's request and hurt people's health. For example, part of Rn release in air, absorbed by people, destroy cell structure.αradial of Rn cause cancer. For researching to geogas distribution and release, it has importance significance for city layout and t environment conservation.
