Depth Profile Of Natural Radionuclides In The Soil Around The Consolidated Tin Mine Site Bukuru-Jos, Nigeria

Abstract

The depth profile of the natural radionuclides namely: 40 U; 238 U and 232 Th in the soil around the consolidated Tin mine site, Bukuru-Jos of Plateau State was examined in this study. Gamma scintillation spectrometry with Nal (TI) was used for the analysis. Results revealed that the average concentration of 40 K is highest at a depth level of 20 – 25cm and lowest at 25-30cm 238 U is highest at 10 – 15cm and lowest at 25-30cm while 232 Th is also highest at the level 10-15cm and lowest at 15-20cm. The results to the large extent indicate no particular trend. KEY WORDS: Radioactivity, radionuclides, soil, scintillation, gamma. Global Journal of Environmental Sciences Vol.3(1&2) 2004: 1-6
