热辐射密度以核爆点距离平方倒数的速度衰减，爆炸、冲击波、致电离辐射效应的衰减速度则更快。
The intensity of thermal radiation decreases only as the inverse square of the distance from a nuclear detonation, while blast, shock, and prompt ionizing radiation effects decrease more rapidly.
并且它还是仪器校准的标准程序之一，甚至作为度量单位使用，“millicrab”译注：即千分之一的蟹状星云辐射密度。
It's routinely used for instrument calibration and even as a unit of measure, the "millicrab."
在旅程中，他们会遭受高强度的辐射，提高了生命后期得癌的几率，骨头的密度也会随之降低。
During the trip itself, they will be subjected to high doses of radiation, raising their odds of getting cancer later in life, and they will lose bone density.
