摘要
本文介绍在苏联切尔诺贝利核电站事故后,采用Ge(Li)反康普频γ谱仪计算机系统对西安地区放射性落下灰、空气气溶胶和莴笋叶进行的分析和获得的各种放射性核素污染浓度。以这些数据为基础,利用某些模式,对西安地区受这次事故放射性污染后的环境质量进行评价,并与我国一些地区放射性污染的环境质量进行比较。同时估算西安地区居民受到这次事故污染所致的辐射剂量,并作出卫生学评价。
After Chernobyl nuclear reactor accident, (by using an Ge(Li) anti-Compton gamma-ray spectrometer, we (analyzed) fallout, aerosol and lettuce leaves in Xi'an area and knewthe contamination levels by radionuclides.On the basis of the data and making use ofsome models of evaluation, we evaluated the environmental quality in Xi'an area andcompared it with that in other areas in China following the accident. The radiation hazard to the public in Xi'an area was discussed and health evaluation was made.
