Susceptibility of Radon Measurement Devices to Electric Fields

This paper examines the possible occurrence of errors due to electromagnetic interferences during radon air concentration measurements. Using SIMULINK, two measurement methods were simulated and compared in terms of their susceptibility to perturbations. After analyzing the detection chamber and the analogue input stage, a method for eliminating the parasitic pulses passing through two measurement channels is described. The subsequent measurements were performed in areas exposed to high electromagnetic field levels and then compared with results obtained in areas with lesser exposure to electromagnetic fields. Two sets of final measurement results were presented by using alternatively an electronic measuring device as well as track detectors.
