碘化钠NaI(Tl)单晶闪烁探测器由射线探测器、计算机多道、高压电源及线性放大器、计算机多道脉冲幅度分析器等部分组成.当放射源发出的γ射线进人闪烁体时,γ光子即与闪烁体中的原子、分子及晶体系统发生相互作用(如光电效应,康普顿散射和电子对效应等).
碘化鈉NaI(Tl)單晶閃爍探測器由射線探測器、計算機多道、高壓電源及線性放大器、計算機多道脈遲幅度分析器等部分組成.噹放射源髮齣的γ射線進人閃爍體時,γ光子即與閃爍體中的原子、分子及晶體繫統髮生相互作用(如光電效應,康普頓散射和電子對效應等).
전화납NaI(Tl)단정섬삭탐측기유사선탐측기、계산궤다도、고압전원급선성방대기、계산궤다도맥충폭도분석기등부분조성.당방사원발출적γ사선진인섬삭체시,γ광자즉여섬삭체중적원자、분자급정체계통발생상호작용(여광전효응,강보돈산사화전자대효응등).
Sodium iodide NaI (Tl) single crystal scintillation detector is composed of the radiation detector, computer multi-channel, the high voltage power supplies and linear amplifiers, computers multi-channel pulse amplitude analyzer.γ-ray issued by ray radiation sources get into the scintillator, and react with the scintillator of atoms, molecules and crystal system (eg.photoelectric effect, Compton scattering and electron pair effect,etc).
