The laboratory is equipped with two calibration chambers (volume: 200 and 600 liters), two radon sources (Ra-226 activity: 21,6 kBq and 52,3 kBq ), a pump, a flow meter, a manometer, etc. Range of obtained radon concentrations is from 35 kBq/m3 to 244 kBq/m3. The computer software has been elaborated for planning and controlling the calibration procedure.polReport
