3·Ionizing radiation is a two-edge sword.

电离辐射是一把双刃剑。

4·Are people normally exposed to ionizing radiation?

人们是如何暴露在电离辐射下的？

5·physical carcinogens, such as ultraviolet and ionizing radiation;

物理致癌物质，例如紫外线和电离辐射；

6·Ionizing radiation exposure is measured as absorbed dose in gray (Gy).

电离辐射的暴露以戈瑞(Gy)“吸入的剂量”来衡量。

7·Radiation injury: Tissue damage caused by exposure to ionizing radiation.

辐射伤害：曝露在电离辐射中造成的组织损伤。

3·Irradiation exposes food to a low level of ionizing radiation to kill bacteria, molds, yeasts, parasites, and other microorganisms that can lead to food spoilage and illness if untreated.

辐射是将食品用较弱的电离放射法杀灭细菌，孢子，霉菌，寄生虫和如果不经处理就能导致食品变质和疾病的其他细菌。

4·Of concern in the current situation is ionizing radiation, which is produced by spontaneously decaying heavy isotopes, such as iodine 131 and cesium 137.

目前情况下值得忧虑的是电离辐射，它由重同位素——如碘131和铯137——自发衰变而生成。

5·Radiofrequency waves are electromagnetic fields, and unlike ionizing radiation such as X-rays or gamma rays, cannot break chemical bonds nor cause ionization in the human body.

射频波就是电磁场，但是与X射线或伽玛射线辐射等电离辐射不同的是，射频波不会打破化学键，也不会给人体造成电离辐射伤害。
