摘　　要：越南北平县的钛矿开采过程会造成放射性元素富集并渗透到环境中,为了保护人们的健康,本研究对钛矿开采前和开采过程中产生的放射性污染对环境的影响进行了综合分析。本研究分别使用Radiation Alert Inspector测量?辐射空气吸收剂量率,RAD 7 Electronic Radon Monitor/Sniffer型氡子体测量仪测量氡子体的浓度,美国Protean Instrument公司生产的WPC-1050型总α,总β测量仪测量钛矿周围与企业周围地下水中放射性核素(总α,总β),土壤中放射性核素的测量则使用美国ORTEC公司的多谱GEM-30γ谱仪。测量结果显示,钛矿区开采前?辐射空气吸收剂量率水平较低,在开采过程中和开采后?辐射空气吸收剂量率有所增高,而且环境空气中氡测量水平超标,地下水总α,总β符合越南标准。开采钛矿会使开采区域和开采区域周围50米土壤中的放射性核素含量增高。Processing of titanium mining caused the enrichment of radioactive elements and penetrated into the environment in Bac Binh county of Viet Nam, to protect human health, this study analyzed the impact of radiation before and during the mining titanium process. The radiation ？ lever were measured by Radiation Alert Inspector, RAD 7 Electronic Radon Monitor/Sniffer type radon progeny measuring instrument were used to measured the concentration of radon; total α, β in groundwater were analyzed by Protean Instrument Company＇s production of WPC-1050 type; Measurements of radionuclides in soil was using American ORTEC＇s multispectral GEM-30 ？ spectrometer. In this study, titanium mining ore ？ radiation was in low levels, after the mining process ？ radiation air dose rate has increased; radon measurements in ambient air levels exceeded; total α, total β in groundwater has accorded with Vietnam standards; titanium mining area and mining area makes 50 meters around the radionuclide content in the soil has increased.
