An approximate procedure is proposed for finding the dose from radiation belt electron-induced bremsstrahlung inside spacecraft. A good agreement (to within 10%) with the direct three-dimensional Monte-Carlo calculation is attained when the spacecraft material is homogenized. If a homogeneous slab of material is used to estimate absorbed dose inside a spacecraft, the resultant estimate proves to be up to five times as low as the result obtained using a randomly inhomogeneous distribution of spacecraft material for an electron spectrum in a geosynchronous orbit.
提出了一种估算航天器内部辐射带电子致轫致辐射剂量的近似方法。当对航天器材料进行均匀化处理时，该方法与直接三维蒙特卡罗计算结果吻合良好（误差在10%以内）。如果使用均匀材料板来估算航天器内部的吸收剂量，对于地球同步轨道中的电子能谱，所得估算值比使用航天器材料随机非均匀分布得到的结果低至五倍。
