低剂量电离辐射对人体健康影响的研究现状

Research Progress on Effects of Low Dose Ionizing Radiation on Human Health

电离辐射是一种无阈值的致癌物,然而,长期低剂量电离辐射对机体的影响机制一直不甚清楚。放射工作人员是长期暴露在低剂量的电离辐射环境中的主体。本文通过调研国内外相关文献以期阐明低剂量电离辐射在细胞水平、组织或器官水平以及癌症发生风险等方面的影响。

Ionizing radiation is considered as a non-threshold carcinogen.However,the mechanism of long-term low-dose ionizing radiation on the body has been very unclear.Radiation workers are the main subjects of long-term exposure to low dose ionizing radiation.Weinvestigated the relevant domestic and foreign literatures in order to clarify the impact of low-dose ionizing radiation on cell level,tissue or organ level,and cancer risk.
