Radon-222 Exposure from Groundwater Ingestion and Tissue Lead as a Potential Indirect Biomarker of Internal Exposure in Wistar Rats
Groundwater is the dominant source of drinking water in Southwest Nigeria, yet radon-222 (Rn-222), a naturally occurring radioactive gas linked to internal radiation exposure, remains largely unmonitored in this supply. This study investigated tissue lead (Pb) concentration as a potential indirect biomarker of internal...
