Abstract

Indoor radon activity concentrations and radon doses on the ground floor and basement floor of 19 schools (kindergardens, primary schools, secondary schools, and high schools) and thermal spas of Ilgin district in Konya, have been measured using the AlphaGUARD PQ 2000PRO radon detector, for three days in the first half of 2016. According to the results, while the indoor radon concentration for only one location, in total, is above the Turkish action level of 400 Bqm_^–3, the values for 10 locations are above the reference level of 100 Bqm_^–3, recommended by WHO. The calculated annual effective doses for inhalation of the radon in indoor air were also found to be 0.26 µSv for the minimum and 4.36 µSv for the maximum. The parametric distribution analysis is also performed with 3-parameter Weibull distribution and some remarks are provided on radon concentration activity.

Key words: annual effective dose, Ilgin active fault, indoor radon, statistical modelling, Weibull distribution
