Performance comparison of electronic radon monitors

The electronic radon monitors are noted for their convenience and acceptable accuracy. Even so, it is necessary to reassure their data quality regularly. We utilized a performance comparison system for this purpose. The instruments in our laboratories (Alphaguard, RAD7, RTM-2100 and Safety Siren) were tested via the comparison experiments. We conclude that by utilizing this system with the concept of calibration factor, it can be helpful to decide whether to send the monitors back to the original manufacturers for adjustment. - Highlights: • The electronic radon monitors are noted for convenience and acceptable accuracy. • A performance comparison system is utilized to assure the data quality. • It is helpful to decide whether to send the monitors for factory calibration
