胸部X线透视目前广泛应用于健康检查,据国内有关资料报道,健康人接受一次胸部X线透视,皮肤照射量为14—78毫伦,即可观察到淋巴细胞染色体畸变率和断片率高于正常的现象。为保障儿童健康、正确使用X线诊断提出依据,以及为估算群体辐射剂量提供参考,1982年我们对健康检查胸部X线透视的入托儿童,局部皮肤接受X线照射量进行了调查,并提出了降低受检者照射量的防护措施。内容和方法调查内容1982年8月对本区4个街道医院155名入托前儿童常规胸部X线透视检查时,监测了一次胸透局部皮肤接受的X线照射量。对
Chest X-ray is currently widely used in health examination, according to domestic data reported that healthy people to accept a chest X-ray, the skin irradiation dose of 14-78 millimeters, you can observe lymphocyte chromosome aberration rate and fragment rate higher than normal phenomenon. In order to protect the health of children, the basis for the correct use of X-ray diagnosis, and to provide a reference for estimating population radiation dose, we investigated the amount of X-ray irradiation on the skin of healthy children undergoing X-ray examination of chest X-ray in 1982 and proposed Protective measures to reduce exposure of subjects. Contents and Methods Survey contents In a routine chest X-ray examination of 155 pre-care children in 4 street hospitals in the district in August 1982, the amount of X-ray radiation received on the thoracotomy part of the skin was monitored.
