Abstract
Abstract A 10 cm (diameter) x 7.5 cm NaI(Tl) gamma-ray spectrometer was used to measure the concentrations of 40K, 232Th and 238U in 50 samples of top soils of the southern and western coasts of Viti Levu, the largest island of the Republic of Fiji Islands. The average activities of 232Th, 238U and 40K in soils of this region were 2.8, 3.6 and 160 Bq kg-1, respectively. The average external gamma-dose, which is likely to be delivered to the local population in this region, is estimated to be 10.3 nGy h-1, well below the world average.
