放射科影像DR检查的辐射危害严重吗 范秀丽 山西省肿瘤医院 ??常规的检查危害可以忽略不计。以胸片作为例子，DR胸片是目前医疗辐射中辐射剂量较低的检查项目，??一次DR胸片正位只有0.023个毫西弗?胸透辐射量，是现在DR胸片的几十倍，所以现在临床上一般很少用胸透检查，??CT辐射剂量也是DR的上百倍。其实每次DR胸片的辐射量微乎其微，再加上与此同时人体是不断进行新陈代谢的，??因此偶尔的胸片检查对人体健康的影响几乎没有，??但是射线毕竟对生物细胞有杀伤致畸的作用，如果没有临床必要不建议过度检查，对于备孕中的男女，在备孕前半年内要避免放射检查，儿童由于机体的免疫功能未发育完全，及其对射线敏感性较高，也建议减少非必要的放射检查，??如果必须检查，需要做好防护，比如对某些腺体，尤其是对于性腺的防护，避免不必要的放射损伤。 Is the radiation hazard of Dr examination serious The hazards of routine inspection can be ignored no Take chest film as an example DR chest radiograph is the examination item of low radiation dose in medical radiation at present Only 0.023 millisieverts are on a DR chest radiograph Transthoracic radiation Dozens of times more than DR chest film Therefore, it is seldom to use chest X-ray examination in clinic The radiation dose of CT is hundreds of times of Dr In fact, the radiation amount of every DR chest film is very small Plus, at the same time, the human body is in the business of continuous metabolism Therefore, the occasional chest X-ray examination has little effect on human health But after all, radiation can kill and teratogenesis biological cells Do not recommend over examination bed if there is no clinical necessity For men and women in pregnancy Half a year before pregnancy, avoid radiation examination Children are not fully developed due to their immune function High sensitivity to radiation and It is also suggested to reduce unnecessary radiation examination If you have to check the fire Need to do a good job of protection For example, for some glands Especially for gonadal protection Avoid unnecessary radiation damage
