摘要
本文探讨用外照射的小水箱来测量后装放射源活度的方法，测量的结果说明测量时在水箱上加盖补偿物的必要性。并由此得出表面敷贴放疗剂量与体内治疗剂量计算的方法应有区别。
The paper discussed the method of measuring afterloading radiation source activity with small waterphantom. The result explained the necessity of laying replenisher on water phantom, and a conclusion was drawnthat there should be difference between the dose computation of surface applicator brachytherapy and interstitialand intracavitary brachytherapy.
