Waheed, A. Rahman, M. Daud, Jamshed H. Zaidi, S. Ahmad] As a major requirement for adopting a well-defined quality system for our instrumental neutron activation analysis laboratory regular participation in the IAEA intercomparison exercises is carried out in routine. IAEA marine sediment (IAEA-433) as a proposed reference material has been studied and thirty elements have been determined employing appropriate irradiation, cooling and counting protocols using instrumental neutron activation analysis (INAA) technique. Employing the same protocols on IAEA SL-1 and IAEA 405 certified reference materials the method has been validated and our values show good agreement with the certified values predicting good accuracy. Miniature neutron source research reactor has been utilized for this work. The results for the IAEA-433 present good precision of less than 5% for Mn, Hf, Sm, Th, Al and Fe whereas for Rb, Tb, V, Se, Ga, Sn and Zn results are with comparatively poor precision ranging 10%-13%. © 2004 Oldenbourg Wissenschaftsverlag GmbH Laboratory techniques, experiments nationallicence Analytical chemistry nationallicence Inorganic chemistry nationallicence Waheed S. aut Rahman A. aut Daud M. aut Zaidi Jamshed H. aut Ahmad S. aut Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 92/12/2004(2004-12-01), 939-944 0033-8230 92:12/2004<939 2004 92 ract https://doi.org/10.1524/ract.92.12.939.55108 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/ract.92.12.939.55108 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Waheed S. aut NATIONALLICENCE 700 1- Rahman A. aut NATIONALLICENCE 700 1- Daud M. aut NATIONALLICENCE 700 1- Zaidi Jamshed H. aut NATIONALLICENCE 700 1- Ahmad S. aut NATIONALLICENCE 773 0- Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 92/12/2004(2004-12-01), 939-944 0033-8230 92:12/2004<939 2004 92 ract CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
