Bituminous mixtures - test methods for hot mix asphalt - part 7 : determination of bulk density of bituminous specimens by gamma rays ; german version en 12697 - 7 : 2002 沥青混合物.热混合沥青的试验方法.第7部分:采用伽玛
So far , we have discussed telescopes for visible light . there are telescopes for radio waves , infrared , x - rays and gamma rays 除了我们讨论过的可见光望远镜外，有些望远镜是用来观测无线电波红外线x射线或伽玛射线的。
Measurements of compton recoil electron spectra caused by the gamma ray are detected by a nominal 5 . 08cm - diam 5 . 08cm - long bc - 501a scintillator detector Bc - 501a液体闪烁探测器用于测量射线产生的康普顿反冲电子谱。
New nasa telescope glast can detect gamma rays and will reveal aspects of the universe unexplored by man so far 美国太空总署一款最新的天文望远镜glast能侦测到伽玛射线，同时也将能揭露至今尚未被人类探测到的宇宙。
Non - destructive testing - radioscopic testing - part 3 : general principles of radioscopic testing of metallic materials by x - and gamma rays 无损检验.射线检验.第3部分:用x -射线和射线进行金属材料的射线检验的一般原则
It works by delivering beams of gamma rays into the human body from various directions and focusing them on the target tissue 它将许多束很细的伽玛射线从不同的角度和方向照射进人体，并使它们都在一点上汇聚起来形成焦点。
Protecting living things from charged particles , as well as from high - energy radiation such as gamma rays , is trickier than shielding against uv 要保护生物免受带电粒子及射线这类高能辐射所害，比遮蔽紫外线还煞费周章。
Radiation , either as low level long - term environmental gamma rays or as higher dose therapeutic radiation , can also produce genetic mutations 不管是周围环境中低水平长期的射线的作用，还是高剂量的放疗都会导致基因突变。
The peak wavelength of the radiation equals the radius of the hole ; for a one - kilogram hole , it corresponds to extremely intense gamma rays 最强辐射所对应的波长等于黑洞的半径；对于一公斤的黑洞而言，所对应的是极强烈的射线。
Gamma ray bursts are high - energy transients in the gamma ray portion of the elctromagnetic spectrum that seem to be isotropically distributd in the sky 珈玛射线爆发是一种在天空中呈现等向分布之电磁波中珈玛射线部分的高能瞬变。
