摘要
目的 提高放射治疗吸收剂量测定精确度。方法 根据我国现行规程与IAEA 规程,用指型电离室测定光子和电子束在水体模参考点吸收剂量。结果 两种方法测得值< 3-0 % 。结论 应用IAEA 规程,保证吸收剂量的测定。
Objective\ To improve the absorbed dose precision of radiotherapy. Methods\ Acording to present rules in our country and IAEA rules, ionization chamber was used to measure photon and electron beam absorbed dose in water model. Results\ The valus of meansurment by two means were fewer than 3 0%. Conclusion\ Applying IAEA rules may guarantee measurement of absorbed dose.
