不同剂量率的放射生物效应不同。我院常规镭疗剂量率约为1.5γ/分,新设计的~(60)钴后装治疗机剂量率增大近80倍。高低剂量率放射生物效应比值如何?这对制订高剂量率~(60)钴后装治疗方案有一定
Radiobiological effects at different dose rates are different. Our conventional radiotherapy dose rate of about 1.5γ / min, the new design of ~ (60) cobalt afterloading treatment machine dose rate increased nearly 80 times. What is the ratio of radio-bioavailability at high and low dose rates? There is a definite rationale for establishing a high dose rate ~ (60) cobalt afterloading program
