Unlike a real spaceflight , mission participants will not be subjected to the debilitating effects of weightlessness and ionizing radiation .

与真正的宇宙飞行不同的是，参与该任务的队员不会受到失重和电离辐射的致衰弱的作用。

The scanning machines , called " backscatter scanners , " deliver a dose of ionizing radiation equivalent to 1 percent or less of the radiation in a dental x-ray .

这种叫做反向散射扫描仪的仪器，在扫描过程散发的电离辐射量相当于或甚至小于一次牙科x摄片中的1%。

If dioxin and ionizing radiation cause cancer , then it stands to reason that less exposure to them should improve public health .

要是戴奥辛和游离辐射会致癌，那麽理所当然，减少暴露其下应该能增进公众的健康。

The x-rays are a form of ionizing radiation , that is , radiation powerful enough to strip molecules in the body of their electrons , creating charged particles that cause cell damage and are thought to be the mechanism through which radiation causes cancer .

x射线是一种电离辐射形式，辐射强度足以脱去电子所在体的分子，创造可以伤害细胞的充电粒子，并且这被认为是辐射致癌的机制。

On the highly energetic end of the spectrum is ionizing radiation - like x-rays or cosmic rays - that are so powerful they can tear away electrons from atoms and molecules and penetrate barriers like the skull and the brain .

光谱的高能量端是电离辐射，比如x光线或者宇宙射线，它们的能量足以使电子从原子和分子中分离出来，也可以穿透像头盖骨和脑部这样的障碍物。
