The danger of superficial radiotherapy for benign dermatoses has been exaggerated. It is safe if certain precautions are observed. The permissible life time maximum cumulative dose of conventional superficial X rays generated at 50 kV given to any area of skin is 1000 R, and of grenz rays, 5000 R.
浅层放射疗法用于治疗良性皮肤病的危险性被夸大了。如果采取某些预防措施,它是安全的。给予皮肤任何部位的50千伏产生的传统浅层X射线的允许终生最大累积剂量为1000伦琴,而接触格伦兹射线的允许终生最大累积剂量为5000伦琴。
