摘要
Abstract
The project of Beijing Electron-Positron Collider Ⅱ (BEPC Ⅱ) was successfully completed in May 2009 and Beijing Radiation Safety Technology Center carried out the radiation survey for the final acceptation of BEPC Ⅱ.The results showed that,in normal operation,the maximum annual effective dose for the occupational staff was 2.03 mSv and 11.7 μSv for the public,both were less than the specified limits.The power density values measured at sensitive points in the electromagnetic environment inside and outside of the experimental area were lower than the national standard limit of 0.4 W/m2.The activity density of natural radionuclide in the soil samples fell in the range of natural activity density.For the secondary loop cooling water from BEPC Ⅱ electron linac the total alpha activity concentration was 0.03 Bq/L and the total beta activity concentration was less than 0.014 Bq/L,both were below the standard limit.The total alpha and the total beta activity concentrations in the groundwater were both less than 0.1 Bq/L as class Ⅰ groundwater.关键词
