Assessment of age-dependent inhalation doses and population attributable risk from radon exposure in water samples from the industrial area of Igbesa, Ogun State, Nigeria
Indoor air radon due to radon in potable water results in inhalation radiation exposure. In this study, age-grouped annual effective inhalation doses for infants (15 years), and population attributable risk (PAR) for lung cancer are calculated based on the radon activity in 20 water samples of…
