Abstract Neutron activation analysis was used to determine129I in soil and grass samples around a reprocessing plant. The method involved wet oxidation of samples, using chromic acid, followed by distillation, collection of iodine in alkaline solution, loading on Dowex-1, irradiation and post-irradiation purification steps. The γ-activity of130I isotope of the purified samples was measured for quantitative determination of129I. The experimental results showed that129I and the129I/127I atomic ratio in soil samples varied from 1.09×10−4 to 5.33×10−3 pCi g−1 and 0.10×10−6 to 6.12×10−6, respectively. Further, the geometric mean of soil-to-plant transfer factor (Bv) for129I was found to be 0.16 which was comparable with other published values.
