Description
A variety of certified reference materials(CRMs) has been developed by standard institutes like NIST(USA), IRMM(EU), KRISS(Korea) and has been supplied for quality control with respect to industrial production as well as research and development. ISO Guide 35 describes the certification of reference materials in terms of general and statistical principles. In order to produce CRMs, a homogeneity study is indispensable as it is stated in ISO guide 35. This work performed a homogeneity test for a candidate soil reference material by using Neutron Activation Analysis(NAA). Five elements such as As, Co, Fe, Na and Th, which have highly precise gamma-ray counting statistics were chosen to fulfill the homogeneity test through a preliminary experiment. Measured results for the five elements were evaluated in a statistical way
