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.

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。

To make sure the iPhone didn't generate too much radiation, Apple built models of human heads — complete with goo to simulate brain density — and measured the effects.

为了确保iPhone产生的射频辐射在规定的范围内，工程师们专门建立了几个仿真人类头部的模型，其中包括仿真大脑的粘状物，来测定辐射对于大脑的影响。

The possibility of the stimulated radiation at the low atomic density is demonstrated, and the possibility of impurity examination by means of stimulated radiation signals is estimated.

证实了在低原子浓度下探测受激辐射的可能性，并估计了用受激辐射信号检测杂质的可能性。

Epidemiologic studies over the past 40 years have identified numerous risk factors for breast cancer, including: older age, an early age at menarche, a late age at first full-term birth, not having children, a family history of breast cancer in a first-degree relative, greater height, higher circulating estrogen levels, postmenopausal hormone use, breast density, history of breast biopsies, obesity (for postmenopausal breast cancer), and exposure to ionizing radiation.
