The Guanzhong "Yixianliangdai" Environmental Radon Level Characteristics Research

At present,radioactive gas radon is the second major cause of lung cancer.With the wide application of atomic and generally improve the development of science and technology and people's living standards to the investigation of natural radioactivity ecological environment especially investigation of radon background has been paid attention to people all over the world.The "Yixianliangdai" is the center of Xi'an City,the Longhai railway section of Shaanxi and Bao Tong Highway as the axis,the national hi tech Industrial Development Zone and Guanzhong national Guanzhong Spark Industry Strip as the basis,which are connected to,formation of high-tech industry economy characteristics.The method on the spot investigation and data consolidation,to carry out the investigation of radioactive radon concentration of Guanzhong area in and around the city center high tech Industrial Development Zone,understand the regional radon background condition,is conducive to the economic development of our province's planning and living environment improvement.The "Yixianliangdai" environmental radon concentration investigation range in Guanzhong area of Shaanxi Province,an area of about 21000km2.In the region,mainly for the Quaternary loess carried out the measurement of radon concentration in soil,the regional center of the city for measuring radon concentration in ambient air.Through the investigation,the basic identification of the Guanzhong "Yixianliangdai" in surface soil radon concentration distribution characteristics,find out the soil radon background value,delineates 7 relatively high background area,analyzes the causes of high background area;find out the air radon concentration in Guanzhong area center city's characteristics,and to the public due to dose equivalent the estimates were in the normal range;the establishment of Guanzhong area environmental radon level geographic information system.The results of the project for the government and relevant departments in the urban construction planning,economy,agricultural development and deployment and other aspects provide an accurate and reliable basis of natural radioactive environmental investigation and evaluation data for the local economic development and planning and improve the people's living environment has played a positive role.
