DESCRIPTION:Speakers: Ibrahim Ayodeji Bello (Kabba College of Agriculture\
 , Ahmadu Bello University)\nThis study evaluated organ-specific annual eff
 ective doses and excess lifetime cancer risk (ELCR) from radon exposure th
 rough 20 groundwater samples in a selected population. The experiment was 
 analysised using Liquid Scintillation Counter (LSC).  Radon concentrations
  ranged from 10.6 to 43.1 Bq/L\, with over 90% of samples exceeding the U.
 S. EPA limit of 11.1 Bq/L\, though remaining below the WHO limit of 100 Bq
 /L. Total annual effective doses ranged from 34.4 to 140.1 µSv/year\, wit
 h the lungs receiving the highest organ-specific dose (up to 13.0 µSv/yea
 r)\, followed by the stomach. Estimated ELCR values (1.21 × 10⁻⁴ to 4
 .90 × 10⁻⁴) exceeded the EPA's acceptable threshold of 1.00 × 10⁻
 ⁴ in most samples\, suggesting a notable radiological health risk. Inhal
 ation was the dominant exposure pathway. These findings underscore the nee
 d for regular monitoring\, public awareness\, and mitigation measures in a
 reas with elevated groundwater radon levels.\n\nhttps://indico.tlabs.ac.za
