Abstract

Abstract Few and sporadic measurements are so far available on the characteristics of indoor radon and thoron daughters in typical Mediterranean areas. For this reason, a pilot study is being carried out in Rome, to study the equilibrium factor F and the influence of ventilation rates in realistic domestic environments. Preliminary data show both a significant influence of ventilation on indoor Rn and Tn daughter concentration and a non-negligible contribution of Tn daughters to the annual effective dose of inhabitants.
