在目前防护条件下,由于职业因素而引起急性放射性皮肤损伤的可能性很小。但因缺乏放射防护知识,管理不善,违章使用射线装置,仍有可能使身体局部受到较大剂量照射,造成急性皮肤损伤。本文就一起违章使用X射线探伤机致急性放射性皮肤损伤一例报道如下。患者,男性,31岁。探伤工人。1991年7月9日因左手腕部扭伤,擅自使用该厂一台工业X射线探伤机摄片检查,当时左前臂背侧皮肤置于X射线管头约10cm处,直接曝光两次,连续开机7分钟左右,局部受照剂量估算约为15Gy。照射当时无明显不适感,第三天局部皮肤出现红斑,逐渐充血水肿,并感灼痛,即在当地医院涂用雪花膏治疗无效,两周后因局部肿胀,出现水泡,疼痛难忍而转入本院。入院检查,见左前臂至手背部有10×30cm的皮肤已呈深褐色,局部明显肿胀,中心部位有3×5cm的水泡区。入院三天后,水泡范围逐渐扩
Under current defensive conditions, there is very little chance of acute radiation-induced skin damage due to occupational causes. However, due to the lack of knowledge of radiological protection, poor management and illegal use of ray devices, it is still possible to expose the body part to larger doses and cause acute skin lesions. This article on the use of illegal use of X-ray detection of acute radioactive skin lesions caused by a report is as follows. Patient, male, 31 years old. Testing workers. July 9, 1991 due to left wrist sprains, unauthorized use of the factory an industrial X-ray inspection machine radiography, when the left forearm dorsal skin placed X-ray tube head about 10cm, direct exposure twice, continuous boot About 7 minutes, the local dose is estimated to be about 15Gy. There was no obvious discomfort at the time of irradiation. On the third day local skin erythema, gradual congestion and edema, and burning sensation, that is, the local hospital was treated with vanishing cream ineffective, two weeks later due to local swelling, blisters, pain intolerable Our hospital. Admission examination, see the left forearm to the back of the hand has 10 × 30cm skin has been dark brown, local obvious swelling, the central part of the 3 × 5cm blisters area. Three days after admission, the blister area gradually expanded
