Public Health England (PHE) and its predecessor organisations have held intercomparison exercises for passive radon detectors for many years. In 2014, 22 laboratories from 10 countries took part and a total of 27 sets of detectors were exposed in the PHE radon chamber.

The detectors were exposed to 5 different radon concentrations and then returned to the originating laboratories for processing. Each participant was asked to return results for each detector in terms of exposure to radon. A parameter, referred to as measurement error, was used to evaluate the performance for each exposure separately and to classify results.

Results have been reported to individual participants and are presented here.
