| 摘 要： | 摘要：用美国医学物理家协会工作组43号报告（AAPM TG №43）方法计算了125I种子源体内近程治疗源吸收剂量及其 剂量场分布，并用热释光剂量计（TLD）测定了125I种子源剂量场分布。理论计算和实际测量结果均表明，种子源剂量随距离呈指数衰减，而且在10 mm内衰减很快，说明种子源剂量基本集中在近距离范围内。

| Abstract: | The absorbed dose and the distribution of dose field in body on ~(125)I brachytherapy seed source are calculated used AAPM TG No.43,and measured by TLD.Both the theoretical calculation and the experimental measurement are agreeable.The obsorbed dose of seed source is the exponential decay with the increase of distance.Moreover,the decay is decreased quickly within 10 mm distance range.It shows that the dose of seed source concentrate basically on the short distance range. |
