A. M. Arogunjo

Abstract

The natural radionuclides contents of cowpea (Vigna unguiculata L walp), guinea corn (Sorghum bicolor L), rice (Oryza sativa L) and soyabean (Glycin max L) have been investigated. The specific activities ranged from 36.4 ± 13.5 Bqkg-1 to 186.9 ± 23.1 Bqkg-1 for 40K, 0.2 ± 0.1 Bqkg-1 to 1.4 ± 0.5 Bqkg-1 for 238U, and 0.3 ± 0.1 Bqkg-1 to 1.8 ± 0.7 Bqkg-1 for 232Th. Cesium - 137 was not detected in any of the cereals investigated.
