摘　　要：阐述了核辐照技术在宝石学中的应用原理和方法。对用于宝石改色处理的核辐照源的特点及其作用以及宝石辐照赋色机制与效应进行了探讨。揭示由辐照损伤法产生的电子缺陷心的形成机理 ,并拟定适合辐照改色处理的实验方案。The application principles and methods are demonstrated of nuclear radiation technique in gemmology. Also discussed are characters and application of the nuclear radiation sources for the gem colour-enhancement process, and the mechanics and effect of the gem colour induced by radiation. The formation mechanism of electronic defect centre caused by radiation damage method is indicated and the appropriate experimental plan is provided for gem radiation colour-enhancement process.
