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.
讽刺的是,对人体暴露于类似原子弹辐射和癌症放射疗法的后果的研究显示,产生脑脊膜瘤的最主要的环境风险因素是离子辐射。
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,现今影响大多数人的离子辐射的主要源头既不是原子弹的辐射尘埃也不是放射疗法,而是牙科X光。
verb
1.Become converted into an ion or ions; undergo ionization.
‘Bursts that occur later, after hydrogen has ionized, don’t have such a gap.’
‘The atoms become ionized by the sun’s ultraviolet radiation and are then accelerated to enormous energies by the solar wind.’
2.Convert (an atom, molecule, or substance) into an ion or ions, typically by removing one or more electrons.
‘Other detectors depend on the electrons from a decay to ionize other atoms and produce an electric current proportional to the decay energy.’
‘The complete spectrum of radiation from the sun contains a significant amount of high energy ultraviolet light and the energy of these photons is sufficient to ionize atoms or molecules.’
