目的通过对钴-60医用γ远距离治疗机的验收检测,提出和分析钴-60医用γ远距离治疗机检测中遇到的问题,为放射治疗设备性能检测提供科学依据。方法使用PTW UNIDOSwebline剂量仪和RT200S二维扫描水箱,以《医用γ射束远距离治疗防护与安全标准》(GBZ161-2004)为依据对钴-60医用γ远距离治疗机进行了验收检测。结果新进钴-60医用γ远距离治疗机存在着不合格检测项目,通过修正之后达到了国家标准的要求。结论对新进钴-60医用γ远距离治疗机进行验收检测必不可少。对不合格检测项目的修正是非常重要。
Objective To detect and evaluate the detection of cobalt-60 medical γ remote-distance therapeutic machine through the acceptance test of cobalt-60 medical γ-distance treatment machine, and to provide a scientific basis for the performance testing of radiotherapy equipment. Methods The PTW UNIDOSwebline dosimeter and the RT200S two-dimensional scanning water tank were used for acceptance testing of the cobalt-60 medical γ tele-distance treatment machine based on the standard GBZ161-2004 for protection and safety of medical γ-rays. Results of the new cobalt -60 medical γ remote treatment machine there are unqualified test items, after the amendment reached the national standard requirements. Conclusion The new cobalt-60 medical γ remote treatment machine for acceptance testing is essential. Correction of non-conformity test items is very important.
