A low dose rate (40 to 100 cGy per hr) remote afterloading intracavitary therapy unit was evaluated in a clinical environment. 50 patients were treated It was found that this device is indeed an effective means to reduce personnel radiation exposure, especially to those who are performing bed-side care for these patients. However, it was also found that these treatments will be interrupted about 1.5 times per hr, and the overall treatment time can be prolonged by 10 to 50%. Whether this may introduce any difference in biological effect is questionable. Using an upper limit value for alpha j, the cost-benefit analysis shows that at best, this method is only marginally justifiable.
在临床环境中对低剂量率（每小时40至100厘戈瑞）远程后装腔内治疗设备进行了评估。对50名患者进行了治疗。结果发现，该设备确实是减少人员辐射暴露的有效手段，尤其是对于那些为这些患者提供床边护理的人员。然而，还发现这些治疗每小时会中断约1.5次，并且总治疗时间可能会延长10%至50%。这是否会在生物学效应上产生任何差异尚不确定。使用α/β的上限值进行成本效益分析表明，充其量，这种方法只是勉强合理。
