Abstract
시금공정의 시료중의 금의 정성 및 정량을 열중성자에 의한 방사화분석으로 조사하였다. 회수률은 81.0∼93.6%이고 결과는 재현성이 좋았다. 정양적 결과는 γ-Spectrometric photopeak-area counting으로 얻었으며 속중성자반응으로 인한 간섭은 무시할 수 있었다.

12 samples from an assay process chain were submitted to qualitative and quantitative neutron activation analysis for the determination of gold. Gold was detected and quantitatively determined in three samples after a chemical separation consisting of solvent extraction and precipitation steps. Recoveries ranged between 81.0 and 93.6% and results of duplicated determinations were reproducible. Quantitative data were obtained from gamma-spectrometric photopeak-area counting. Interference from fast neutron reactions was negligible.
