Abstract |
|
|
| The activities of gross alpha and gross beta particles in groundwater have common environmental concern. In this research, the activities of alpha and beta particles in groundwater along with the associated health risk were determined to know whether they pose a threat to the Dzamah community. Ten (10) water samples were collected from different part of Dzamah area and transported to Center for Energy Research and Training (CERT) ABU Zaria, to analyze gross alpha and gross beta activity using the single channel gas-filled proportional counter. The results found that the mean activity of gross alpha particle is 0.016671 Bql-1 while for beta particle the mean activity is 0.026092 Bql-1. When these values were compared with the World Health Organization (WHO) reference dose level of 0.1 and 1.0 Bql-1 for gross alpha and gross beta activity respectively, and the reference dose level of annual effective dose of 0.1 mSv y-1, it is found that the presence of alpha and beta activity in drinking water of Dzamah community does not pose any health problem. These results are of great importance for exploring the health risks due to gross alpha and beta concentrations in Dzamah community potable water and may pave the road to a baseline for future changes in environmental radioactivity due to naturally occurring radioactive materials and human activities. |
