摘要
在探伤室环境影响评价中,以192Ir源产生的γ辐射场为例,将经验公式计算结果与实测结果进行对比,得出如下结论:无屏蔽条件下,经验公式估算结果与实际测量结果基本相符;经屏蔽体屏蔽后,用经验公式法估算的结果偏保守,与实际测量值最大相差1个量级。
In the environment impact assessment for the NDT room, the ~/ radiate field generated by radiation source 192 Ir was used for example, comparing the results of empirical shielding calculate and actual measured. According to the results, the value of estimating by the empirical formula method was similar as the actual meas- ured value under no shielding materials. The value of estimating by the empirical formula method after shielding materials is more conservative than the actual measured value by a magnitude.
