Assessment of Background Ionizing Radiation Levels in Selected Markets in Ile-Ife and Modakeke: A Public Health Perspective

Abstract: This study assessed background ionizing radiation (BIR) levels in six markets across Ile-Ife and Modakeke, Southwestern Nigeria, to evaluate potential health risks. Annual effective dose rates (AEDR) were measured and analyzed using a handheld Geiger Counter. Results showed AEDR values ranging from 0.67 mSv/y at Texaco Market to 2.52 mSv/y at Sabo Market. The average AEDR across all markets was below the global population average exposure of 2–3 mSv/y. The findings suggest that BIR exposure in these markets is primarily due to naturally occurring radionuclides in the soil and rocks, with no significant anthropogenic contributions. This study concludes that the BIR levels in these markets pose no significant health risks to users.
