摘要：

采用Monte Carlo方法和热释光剂量计(TLD)法研究¹²⁵I粒子源在水中的剂量分布, 并对计算结果进行比较. 结果表明: 当粒子源活度为1.3×107 Bq, 粒子源的径向距离分别为0.5,1.0,1.5,2 cm时, 用蒙特卡洛方法(MCNP)软件包计算粒子源剂量率分别为11.7,3.3,1.5,0.8 mGy/h, TLD法测量结果分别为12.2,3.1,1.3,0.7 mGy/h; ¹²⁵I粒子源的径向剂量率随距离增加迅速下降. 

Abstract:

The dose distribution of ¹²⁵I source in water was studied by means of Monte Carlo simulations and thermo luminescent dosemeter (TLD) method, and the results were compared. The results show that when ¹²⁵I source activity was 1.37×107 Bq, the radial distances of ¹²⁵I source were 0.5,1.0,1.5 and 2 cm, the dose rates of ¹²⁵I with MCNP method were 11.7,3.3,1.5,0.8 mGy/h, TLD measurements were 12.2,3.1,1.3,0.7 mGy/h; 125I source radial dose rate decreased rapidly with increasing distance.
