电离辐射的生物效应及健康影响

 人们在日常生活中经常接触辐射，却又因为辐射的不易感知等特性对医疗辐射等低剂量电离辐射产生恐惧心理。介绍了电离辐射的来源、生物效应和对健康的影响，讨论了低剂量电离辐射诱导的兴奋效应和适应性反应。通过引导人们正视电离辐射，并采用适当的防护措施，使电离辐射在人类生活中产生的危害作用降低到人体可接受的水平，可让辐射在医学、工业和科研等领域造福人类。

The biological effects and health impacts of ionizing radiation

People are often exposed to radiation in their daily life, but they are also unaware of the low doses of ionizing radiation such as medical radiation because radiation is hard to perceive. In this paper, the source, biological effects and health impacts of ionizing radiation are briefed, and the hormesis and adaptive response of low-dose radiation are discussed. This paper intends to help people to correctly understand ionizing radiation and proposes appropriate protective measures that may reduce the harmful effects of ionizing radiation in human life to some acceptable level for humans, so that radiation can benefit human beings in the fields of medicine, industry and scientific research.
