The energy averaged Boltzmann equation model is applied to the determination of dose distributions in infinite, homogeneous media with uniform, monoenergetic, isotropic source distributions in spherical regions of radius larger than the electron range. The generalization to the case of spherically symmetric source distributions is made. Comparisons with dose distributions calculated by the integration of dose point kernels derived from Monte Carlo calculations are presented.
能量平均玻尔兹曼方程模型用于确定无限大、均匀介质中半径大于电子射程的球形区域内具有均匀、单能、各向同性源分布的剂量分布。将其推广到球对称源分布的情况。给出了与通过对蒙特卡罗计算得出的剂量点核进行积分计算得到的剂量分布的比较。
