在放射性元素蛻变时要放出α,β粒子和δ-射綫。按α粒子、γ-射綫的能量和β-譜的最高能量可以鑑定放射性同位素。目前非常普温地运用γ-譜仪来測量γ-射綫的能量。由于γ-谱仪記录γ-射綫的效率高,它的鑑别能力也很高,既可以用它测量放射性很弱的試样,也可以用它測量放射性很强的試样。γ-谱仪工作很稳定,构造又比較阐单,这些优点引起了放射化学工作的兴趣。γ-譜仪的結构一般都大同小异,图1是列宁格勒大学化学系全体中国同学在祖国大跃进的鼓舞下开始的,現在已仿制成功自动記录γ-譜仪。
In the transformation of radioactive elements to release α, β particles and δ-ray. Radioisotopes can be identified by the alpha particles, the energy of gamma rays, and the highest energy of the beta spectrum. At present, the γ-ray spectrometer is used to measure the energy of γ-rays very ubiquitously. Due to the high efficiency of γ-ray recording γ-ray spectroscopy, its ability to identify high, both it can be used to measure very weak radioactive samples, it can also be used to measure highly radioactive samples. γ-spectrometer work is very stable, relatively simple structure and interpretation, these advantages have aroused the interest of radiochemical work. The structure of γ-spectrometer is generally similar, Figure 1 is the University of Leningrad, Department of Chemistry, all Chinese students inspired by the Great Leap Forward encouragement, and now has been successfully copied automatically γ-ray spectrometer.
