Implication

Observational study reveals indoor radon concentrations and radiation doses in residential dwellings, highlighting meteorological influences on inhalation risk.

Key Points

  • To measure indoor radon (222Rn) concentrations in residential dwellings, examine the influence of meteorological parameters, and evaluate inhalation radiological health risks.
  • Monitored radon levels across 21 residential buildings in Al-Gharraf district, Dhi Qar Governorate, using CR-39 nuclear track detectors.
  • Calculated annual effective dose and pulmonary dose, and evaluated environmental associations using Pearson correlation coefficients.
  • Radon concentrations ranged from 73 ± 29 to 336 ± 82 Bq m−3 (mean: 151 ± 52 Bq m−3), with a mean annual effective dose of 3.8 mSv y−1 and mean pulmonary dose of 6.0 mSv y−1.
  • Radon concentrations exhibited a strong, statistically significant positive correlation with relative humidity (r = 0.815, p < 0.01) and moderate positive correlations with maximum (r = 0.561) and minimum temperatures (r = 0.490).
  • Outdoor wind speed showed a weak, non-significant negative correlation (r = −0.209), while peak radon concentrations in select dwellings exceeded WHO recommended reference levels.
