Gross alpha and beta surveys of Lake Kainji water
A gross alpha and beta survey of the water of Kainji Lake was conducted using multi-channel analyzer, a proportional counter detector. This was done to estimate the gross radioactivity concentrations due to natural radionuclides in the lake water. Radioactivity, a phenomenon that leads to production of radiations, and radiation is known to trigger or induce cancer. The gross alpha and beta activity concentration analyzed in the water shows that the alpha activity ranges from 1.0 x 105 Bq/cm3 to 0.7Bq/cm3 with an average value indication of 0.0702Bq/cm3, whereas the beta activity concentration indicated BDL for all the sites with exception of upstream 01 location (9~' 51' 485' and 4~'35' 473'E) which has 0.0022Bq/cm3. This could be attributed to the continued flow of the lake water. Although radioactivity measured in lakes is usual higher than that of flowing waters, because a significant part of the radioactive substance brought in by other tributary rivers accumulates in it (Szaho et al.1998). That of Kainji Lake is entirely different.
