| 摘 要： | 目的：用蒙特卡罗法和积分演算法计算经核素治疗后的病人对周围人员的照射量。方法：蒙特卡罗模拟法用VB6．0编写程序来计算照射量,积分演算法用“笔－纸”来推算。结果用两种方法分别计算了长方形和椭圆形放射源的照射量,两种方法的差异分别为0．88％、0．61％。结论：蒙特卡罗模拟法的计算结果与积分演算法的结果差异很小,说明用模拟法估算是可行的。

| Abstract: | Objective To estimate exposure dose of personnel around patients by Monte Carlo method and integration method. Methods Exposures were estimated by a Monte Carlo practical program with Visual Basic 6.0 and integration method using "pen-and-paper". Results Exposures for rectangle and ellipse sources were calculated.The difference between different methods for various sources were 0.88% and 0.61%,respectively. Conclusion The results estimated by Monte Carlo method are close to those of integration method.It is illustrated that doses of other people estimated by Monte Carlo method are significant. |
