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，電離輻射，如X射線或伽瑪射線不同，既不能破壞化學鍵，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.(手機產生“非電離”輻射，它不像X或伽馬射線那樣從細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到某一目標的過程叫做“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和X射線；能量強大的阿爾法射線（氦核能量流）和貝塔射線（電子流）也可以破壞細胞組織。)

Objective To assess the value of Gamma knife combined with whole brain radiation therapy for brain metastases.(目的評價腦轉移瘤伽瑪刀聯合全腦放射治療的價值。)

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.(這種強輻射是爆發持續了一分鐘之久的伽馬射線的一部分，這標志著一顆超大質量恒星的死亡同時將自己轉變成一個黑洞。)

The radiation data involved detecting low levels of gamma radiation and suspected alpha/beta particulates in air.(輻射數據包括探測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.(相機屬于放射性核素成像設備。)

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，然后用伽瑪射線進行處理。)
