The energy-averaged transport model for the calculation of dose rate distributions is applied to uniform, spherical source distributions in homogeneous media for radii smaller than the electron range. The model agrees well with Monte Carlo based calculations for source distributions with radii greater than half the continuous slowing down approximation range. The dose rate distributions can be written in the medical internal radiation dose (MIRD) formalism.
用于计算剂量率分布的能量平均输运模型应用于均匀介质中半径小于电子射程的均匀球形源分布。对于半径大于连续慢化近似射程一半的源分布，该模型与基于蒙特卡罗的计算结果吻合良好。剂量率分布可以用医学内照射剂量（MIRD）形式表示。
