A comparison of the analytical data obtained by three k0-NAA software programs was carried out using both the airborne particulate matter collected from an urban site and the certified reference materials of the air filter and urban dust to evaluate the performance of the analysis. The individual k0-NAA standardization methods of three countries, Korea, China and Vietnam which had been modified from the well established k0-program were used for the comparative analysis. The measured concentrations of 30 elements from the two kinds of air samples based on this software were in agreement with each other within about 20% analytical error except for a few elements. By contrast, the results of China and Vietnam were moderately higher than that of Korea due to a systematic error associated with the detection efficiency, gamma peak analysis and geometric effect.

환경의 오염 및 보존에 대한 연구에 적용하기 위한 원소의 조성이 다른 퇴적물 시료중의 33종의 원소농도를 중성자방사화분석을 이용하여 정량하였다. 분석법의 검증과 평가를 위해 3종의 표준물질(NIST SRM 2종과 NRCC CRM 1종)을 선정하여 분석의 정밀도 및 정확도를 측정하고 보증값과 비교함으로서 분석절차를 평가하였고, 최적의 분석조건을 조사하므로서 실제 시료에 적용하기 위한 분석절차를 확립하였다. 시료의 중성자 조사는 한국원자력연구소의 연구용원자로(TRIGA MARKIII & HANARO, neutron flux, 1-3$\times$$10^{13}$n/$\textrm{cm}^2$.s)를 이용하였다. 추가로, 앞에서 정해진 분석절차에 따른 퇴적물 분석의 정확성 및 신뢰도를 확인하기 위해 두 가지 IAEA의 퇴적물 시료를 분석하여 Al, As, Co, Cr, Fe, Sb, Zn 등의 함량값을 XRF, ICP-MS, AAS에 의한 분석결과와 상호비교하였으며, 비교적 잘 일치하였다. For the application of study on pollution and conservation of environment determination of 33 elemental concetrations in different sediment samples were carried out using instrumental neutron activation analysis (INAA). For verification and evaluation of the analytical method, three standard reference materials (two NIST SRMs and one NRCC CRM) were chosen and the accuracy and precision of the analysis were estimated by comparison to the certified values. Under the optimum condition, the analytical procedure to apply a practical sample was estimated. Neutron irradiation of sample was done at the irradiation facilities (neutron flux, 1-3${\times}$10$\^$13/n/$\textrm{cm}^2$$.$s) of the TRIGA MARK-III and HANARO research reactor in the Korea Atomic Energy Research Institute. In addition, analysis of two IAEA's sediment was performed according to the pre-established analytical method. The analytical results of elements such as Al, As, Co, Cr, Fe, Sb and Zn by INAA were intercompared with those of WD-XRF, ICP-MS and AAS, and are relatively agreed with each other.
