Radon is the largest and most variable contributor of radiation dose to the general population. The Centre for Radiation, Chemical and Environmental Hazards (CRCE) of Public Health England carries out international intercomparisons of passive radon detectors each year.
Intercomparisons provide information about the accuracy of measurements. By allowing different detectors to be compared side by side, an objective assessment of the accuracy of measurements can be made.
