30例β射线皮肤辐射损伤其中83.3％为核工业后处理厂的生产人员,60％的病变发生在手部。本组病例Ⅰ度的急性皮肤辐射损伤其剂量为3.17～5Gy、Ⅱ度7～14Gy、Ⅲ度为75—100Gy。远期效应观察发现:Ⅰ度的损伤经数年后复查皮肤无阳性体征,Ⅱ度的病例有6例因故转为慢性放射皮炎,Ⅲ度的全部病例均迁延发展为慢性放射皮炎。远期效应未见癌变:可能观察时间还不够长。所有经外科治疗的病例远期疗效尚好。 Thirty cases of β-ray skin radiation damage accounted for 83.3% of the workers in the nuclear industrial reprocessing plant and 60% of the lesions occurred in the hands. This group of patients with a degree of acute skin irradiation dose of 3.17 ~ 5Gy, Ⅱ degree of 7 ~ 14Gy, Ⅲ degree of 75-100Gy. Long-term effect observation found: Ⅰ degree of injury after a few years to review the skin no positive signs, Ⅱ degree of cases of 6 cases due to chronic radiation dermatitis, Ⅲ degree of all cases of persistent development of chronic radiation dermatitis. Long-term effects have not seen cancer: the observation time may not be long enough. Long-term efficacy of all surgically treated cases is good.
