Completely non-destructive elemental analysis of bulky samples by PGAA

NBAA (neutron beam activation analysis), which is a combination of PGAA and INAA by a single neutron irradiation, using an internal monostandard metho d is proposed as a very unique and promising method for the elemental analy sis of voluminous and invaluable archaeological samples which do not allow even a scrape of the surface. It was applied to chinawares, Sueki ware, and bronze mirrors, and proved to be a very effective method for nondestructiv e analysis of not only major elements but also some minor elements such as boron that help solve archaeological problems of eras and sites of their pr oduction.
