摘要
提出一种新的boundbox法计算γ线穿透各种形状屏蔽物体的衰减量。采用空间坐标变换的方法,建立了各种基本形状屏蔽物体的boundbox的数学模型。该方法用6个平面代替了复杂的屏蔽物体,可快速计算从放射线源到评价点的视线所穿透屏蔽物体的距离,并由屏蔽领域的距离可快速预测辐射屏蔽的衰减率。
A bound box method has been developed for calculating the attenuation of gammaray passing through various shield configurations. Using the method of space alternate coordinate, the bound box mathematical models for various shield configurations have been constructed. This method replaces complex shield configurations with six faces, making rapid calculation of the distance penetrating through the shield configuration from source points to the detector point possible. From the distance through the shielded region, the geometric attenuation can be rapidly determined in advance.
