Abstract
Aims: To determine the level of radioactive pollution in soil samples from mining and non-mining communities in Barking Ladi local government area of plateau State and evaluate the implications for public health.
Study Design: A Comparative Study was conducted using soil samples collected randomly from mining and non-mining communities (four samples from each). The samples were subjected to analysis for gross alpha and beta radioactivity concentration at the Centre for Energy Research and Training, Ahmadu Bello University, Zaria, using a Protean Instrument Corporation (MPC 2000 Dual Phosphor) detector.
Results: The study revealed that the gross alpha activity concentration of the soil was in the range of 0.03747 0.0150 to 0.04995 0.0157 Bq/g, while beta activity concentration was in the range of 0.03995 0.0301 to 0.1357 0.0212 Bq/g. The maximum value of alpha activity concentration was 0.04995 0.0157 Bq/g, and the maximum value of beta activity concentration was 0.1357 0.0212 Bq/g.
Conclusion: The study shows that the radioactive concentrations in soils from both the mining and non-mining communities are below the World Health Organization’s (WHO) recommended standard of 0.5Bq/l and 1.0Bq/l for gross alpha and gross beta in drinking water respectively. Even though these findings show that the soils from the study communities are safe for agricultural activities, it is essential to carry out routine monitoring activities to guard against potential radioactive pollution and protect public health.
