中国环保部门对农业、医疗等民用辐射装置管得很严,但事故还是时有发生辐射防护原则核能和核辐照装置已经走进公众的生活,却仍旧蒙着神秘面纱。我们距离核与放射事故有多远?核与放射事故的危害范围和程度究竟有多大? 生活在地球上,每个人都无法避免放射性照射。我们常说的辐射分为两种:电离辐射与非电离辐射。非 China's environmental protection departments have strict control over the civil radiation equipment such as agriculture and medical care, but the accident has always occurred when radiation protection principles have emerged. Nuclear and nuclear irradiation devices have entered the public life and are still mysteriously hidden. How far are our distances from nuclear and radiological accidents? What is the scope and extent of nuclear and radiological hazards? Living on Earth, everyone can not avoid radioactive exposure. We often say that the radiation is divided into two types: ionizing radiation and non-ionizing radiation. non-
