ACCUMULATION OF RADIOACTIVE TRACE ELEMENTS (40K, 226Ra and 232Th) IN BASSA, PLATEAU STATE, NIGERIA
Keywords:
Radioactive Trace Element; Soil; Plant; Water; Geo-Accumulation IndexAbstract
This work intends to unveil the extent of trace elements (40K, 226Ra and 232Th) accumulation in soil, water and edible plants using Sodium Iodide Thallium Gamma Spectrometry (NaI (Tl)) from 12 sample point each of soil, water and edible plants and assess their carcinogenic role to biological tissue that might result in cancer. The results of this study showed that the Accumulation (Igeo) of soil decreased in the order of 40K (0.334) > 226Ra (0.302) > 232Th (0.259), that of water decreased in the order of 40K (0.252) > 232Th (0.226) > 226Ra (0.197) and that of edible plants decreased in the order of 232Th (-0.940) > > 40K (-1.028) > 226Ra (-1.116). Soil and water in all the study areas are moderately contaminated while edible plants are uncontaminated compared with the World Health Organization limit. It can be concluded that the soil, water and plants in the area required serious concern and regulatory control. Hence this study can be used as a reference data for regulatory bodies like NNRA and the rest
