A Comprehensive Study of Residential, Geogenic and Water Radon in the North Area of Mureş County, Romania

Abstract

This study presents results of a complex survey about residential, soil and water radon in the North of Mureş county (Romania). Indoor radon measurements were performed by using CR-39 track detectors, while radon concentrations in soil and in water were measured by using the LUK3C device and accessories. The indoor radon concentrations of 157 houses ranged from 9 to 414 Bq m-3, with an arithmetic mean of 131 Bq m-3 and a geometric mean of 105 Bq m-3. In ~3.2% of the investigated houses exceed the recommended reference level of 300 Bq m-3. The soil gas radon concentrations in 137 sampling points varied from 5.0 to 88.0 kBq m-3, with a geometric mean of 14.6 kBq m-3. Results of 190 water samples shows radon concentrations from 0.2 to 28.0 Bq L-1, with a geometric mean of 5.0 Bq L-1. Beside these results, indoor, soil and water radon maps were performed, divided into cells of 5 km × 5 km.

Study on atmospheric radioactivity in Suceava Metropolitan Area

“…Cuculeanu et al, 2011 investigated the radon concentrations in the low atmosphere and their correlations with meteorological parameters for Bacău city. Also, the north area of Mures county was analysed, the authours aimed to determine residential radon concentrations, radon concentrations in soil and in waters (Papp et al, 2017. ).…”
