Abstract
The Nigerian Research Reactor-1 was employed in the analysis of iodine in local food samples at an operating flux of 5.0 ×
10
11 ncm−2 s−1. Preconcentration neutron activation analysis (PCNAA) was compared against the most common spectroscopic
(Sandell-Kolthoff reaction) technique, giving a concentration range of 0.295 to 2.960mg/Kg and 0.264 to 2.725mg/Kg, respectively,
with an average percentage deviation of 11.34%and a positive correlation between the methods at 0.89.PCNAAand Sandell-Kolthoff
spectroscopy of NIST 1548a reported values of 0.759 ± 0.06 mg/Kg and 0.751 ± 0.05 with Student’s t-test score of 1 and 0.95 and
percentage standard deviation of 0 and 1.12%, respectively.
