We are presenting a method of calculating the dose-rate distributions in partially shielded field. An attenuator was placed in central beam axis and also in an off-axis geometry. The study was made with a Co-60 radiation and with photons generated by 10 and 23 MV Linac at depths, in phantom, from 5 to 30 cm. To obtain the calculated values of dose-rates; the contributions of the three components to the total dose-rate were measured. The calculated dose-rate distributions agree well with the measured data in case of 10 MV and 23 MV radiation.
我们正在介绍一种计算部分屏蔽场中剂量率分布的方法。在中心束轴以及离轴几何位置放置了一个衰减器。该研究使用了钴-60辐射以及由10兆伏和23兆伏直线加速器产生的光子，在模体中5至30厘米深度处进行。为了获得剂量率的计算值，测量了三个分量对总剂量率的贡献。在10兆伏和23兆伏辐射的情况下，计算得到的剂量率分布与测量数据吻合良好。
