| 摘 要： | 详细计算了一台10 MeV的电子直线加速器周围某些关键位置的辐射剂量,并对其进行了连续监测以及累积剂量的测量,测量结果充分说明工作环境是安全的.在迷宫出口位置理论值很好地符合测量值,这充分验证了经验公式的合理性.同时发现迷道内剂量衰减趋势与计算模型中使用的距离平方反比规律有所不同,要在迷道长度达到一定值后才能确保经验公式给出的结果是保守的.为了实现对辐射场的连续实时监测,此次测量中使用一种新的数据采集设备Mini-DDL(mini digital data logging).

| Abstract: | The radiation dose at some locations round a 10 MeV industrial electron linear accelerator was computed using empirical formulas.The continuous monitoring results and measured cumulative dose data were also presented specifically.These results strongly prove that the working environment is safe.Outside the maze exit,these estimation results coincide well with the measured data,which fully demonstrates the rationality of the empirical formula.Comparing the data from measurement and calculation in the maze,it... |
