Indoor radon concentrations in Vushtrri, Kosovo

Indoor air radon concentration was measured by exposing track-etch detectors in the two elementary schools, one high school, a kindergarten and the hospital in the city of Vushtrri. Measurements were performed with the radon monitor PRM-145, which uses alpha scintillation cells and serves to determine the current concentration of radon. The results we obtained are in the range between the average values of radon for the interior spaces, and values that poses potential risk for lung cancer. Measuring the concentration of radon was done in total of 34 rooms and came up with values which are between 28 Bqm(-3) and 398Bqm(-3). In order to reduce the concentration of radon, we have built a ventilation pump, then we performed repeated measurements and finally came with results between 130-145 Bqm(-3).
