微剂量及微剂量辐射效应

Microdose and microdose effects induced by radiation

介绍发生在分子水平的原发辐射效应,射线能量在微组织水平的沉积,次级电子微剂量效应在细胞损伤中的作用,以及基因微剂量效应对细胞存活的影响,为定量描述各种微观辐射效应,更加准确认识和理解低剂量辐射诱导的各种生物效应,科学评估低剂量辐射的健康危害,引出微剂量和微剂量事件等术语和概念。

Primary radiation effect on molecular level, energy deposition of radiation on micro-tissues, the cellular damage induced by micro-dose effect of secondary electrons and the cell survival contributed by gene micro-dose effect were introduced in this paper. In order to quantitatively describe various micro radiation effects, to understand more accurately evaluated events induced by low dose radiation, as well as to especially estimate the healthy risk exposed to low dose radiation, the items of micro-dose and micro-dose events were introduced.
