The invisible magnetosphere shields us from the dangerous ionising radiation of space.

看不见磁层保护我们免受危险太空电离。

Another big problem is that space is brimming with ionising radiation that rips DNA to shreds.

另问题是太空充满了电离，将 DNA 撕成碎片。

Irradiated foods: meat and dairy produce have ionising radiation applied to them before packaging.

照食：肉类和奶制在包装前会进行电离处理。

These days, however, the main source of ionising radiation for most people is neither fallout from bombs nor radiotherapy; it is dental X-rays.

然而，现今影响多数人离子主要源头既不是原子弹尘埃也不是放疗法，而是牙科X光。

Ironically, because past research studying the after-effects of exposure to things like atom bombs and radiation treatments for cancer suggests the most important environmental risk factor for meningiomas is ionising radiation.

讽刺是，对人体暴露于类似原子弹和癌症放疗法后续影响研究显示，产生脑膜瘤最主要环境风险因素是离子。
