答:什么是内照射以及内照射的危害问:放射性核素进入生物体,使生物受到来自内部的射线照射称为内照射。常见的射线有:α射线、β射线,他们的射程很短,能量会全部呈现到人体中,所以,α射线、β射线是内照射防护的重点。放射性物质进入人体后,通过内部照射引起的损伤为内照射损伤。
中新网12月15日电 据日本共同社报道,日本东京电力公司14日发布消息称,11日在福岛第一核电站受到放射性物质污染的工作人员,今后50年的辐射量初步评估结果为0.38毫西弗,不会对健康造成影响。 资料图:日本福岛第一核电站。
As was written, it is crucial, whether we are exposed to radiation from external sources or from internal sources. This is similar as for another dangerous substances. Internal exposure is more dangerous than external exposure, since we are carrying the source of radiation inside our bodies and we cannot use any of radiation protection principles . The intake of radioactive material can occur through various pathways such as ingestion of radioactive contamination in food or liquids, inhalation of radioactive gases, or through intact or wounded skin. On this place, we have to distinguish between radiation and contamination. Radioactive contamination consist of radioactive material, that generate ionizing radiation. It is the source of radiation, not radiation itself. Anytime that radioactive material is not in a sealed radioactive source container and might be spread onto other objects, radioactive contamination is a possibility. For example, radioiodine, iodine-131, is an important radioisotope of iodine. Radioiodine plays a major role as a radioactive isotope present in nuclear fission products, and it is a major contributor to the health hazards when released into the atmosphere during an accident. Iodine-131 has a half-life of 8.02 days. The target tissue for radioiodine exposure is the thyroid gland. The external beta and gamma dose from radioiodine present in the air is quite negligible when compared to the committed dose to the thyroid that would result from breathing this air.
红网时刻新闻11月9日讯(通讯员 车能雨)近日,由中国医药教育协会主办、广州中医药大学金沙洲医院承办的“中国医药教育协会肿瘤内照射医学专业委员会成立大会暨肝癌综合诊治论坛”在广州成功召开。会上,中国医药教育协会肿瘤内照射医学专业委员会正式成立。
之前一位网友吐槽希望滴滴师傅把自己放在放疗科门口但却被拒绝了原因是放疗科太可怕了……很多老百姓对放疗都是“敬而远之”,认为放疗会产生辐射,而辐射对人体有害。正是因为这种不了解、不知道,让很多患者对放疗产生了恐惧心理,从而影响了治疗时机。既然如此那一起来认识一下放疗吧!
