A method is described for calculating the absorbed dose rate in tissue around encapsulated linear radium- or 137Cs-sources. A variable factor is derived relating this quantity to the absorbed dose rate from the unshielded source in air. This factor depends on a set of geometrical parameters including some data concerning the shape of the source ends.
描述了一种计算封装的镭或铯-137线状源周围组织中吸收剂量率的方法。推导了一个可变因子，将该量与空气中未屏蔽源的吸收剂量率相关联。该因子取决于一组几何参数，包括一些有关源端形状的数据。
