滇西放射性矿地带的区域辐射环境防控研究

目的探索区域尺度的环境保护。方法选择典型区域进而调查论证。结果探讨了含放射性矿地带的区域辐射环境防控的必要性及防控方法。结论天然辐射源存在区域有必要进行区域尺度的辐射环境防控,防控目标的实现可在把握区域环境特征、天然辐射源的分布、放射性核素的地表输移三个前提条件下,通过设置关键防控点的方式来有效实施。

Radiation Dose Monitoring and Analysis for the Construction of the Upgraded Beijing Electron-Positron Collider(BEPCⅡ) During Its Storage Ring Operation

In this paper,the average dose level is introduced in an environment and area when BEPCⅡis debugged. The typical dose graphs are offered when the electronic storage ring is debugged and works in the synchrotron radiation mode.At the same time,some suggestions about radiation protection are presented.All the data indicate that the main and local part shielding satisfy the need and attain the design target.
