Radiofrequency waves are electromagnetic fields, and unlike ionizing radiation such as X-rays or gamma rays, can neither break chemical bonds nor cause ionization in the human body.(射頻波電磁場(chǎng)，電離輻射，如X射線(xiàn)或伽瑪射線(xiàn)不同，既不能破壞化學(xué)鍵，也不在人體造成電離。)

Cell phones produce "non-ionizing" radiation, which, unlike X - or gamma rays, doesn't damage DNA by stripping away electrons from molecules in cell tissue.(手機(jī)產(chǎn)生“非電離”輻射，它不像X或伽馬射線(xiàn)那樣從細(xì)胞組織中的分子里分理出電子，從而破壞dna。)

The gamma radiation reaching a target as a result of scattering in the air is called "skyshine" .(輻射由于空氣的散射而達(dá)到某一目標(biāo)的過(guò)程叫做“天空照射”。)

The most damaging radiation are gamma rays and x-rays; energetic alpha rays (streams of helium nuclei) and beta rays (electrons) can also damage cells.(最具破壞力的輻射是伽馬射線(xiàn)和X射線(xiàn)；能量強(qiáng)大的阿爾法射線(xiàn)（氦核能量流）和貝塔射線(xiàn)（電子流）也可以破壞細(xì)胞組織。)

Objective To assess the value of Gamma knife combined with whole brain radiation therapy for brain metastases.(目的評(píng)價(jià)腦轉(zhuǎn)移瘤伽瑪?shù)堵?lián)合全腦放射治療的價(jià)值。)

The intense radiation was part of a gamma-ray burst that lasted a minute and which marked the death of a massive star transmogrifying itself into a black hole.(這種強(qiáng)輻射是爆發(fā)持續(xù)了一分鐘之久的伽馬射線(xiàn)的一部分，這標(biāo)志著一顆超大質(zhì)量恒星的死亡同時(shí)將自己轉(zhuǎn)變成一個(gè)黑洞。)

The radiation data involved detecting low levels of gamma radiation and suspected alpha/beta particulates in air.(輻射數(shù)據(jù)包括探測(cè)低水平的微克輻射和可疑的alpha/beta微粒。)

Gamma four. Steroids for the inflammation, anticonvulsants for the seizures, radiation for the chemotherapy.(伽馬四型，消炎用的類(lèi)固醇，癲癇用的抗痙攣藥，化療用的放射物。)

Gamma camera belongs to the radiation nuclide imaging equipment.(相機(jī)屬于放射性核素成像設(shè)備。)

It's derived from bee hives in New Zealand and then treated with gamma radiation.(這種蜂蜜提取自新西蘭的蜂巢，然后用伽瑪射線(xiàn)進(jìn)行處理。)
