More than 40 years ago, Public Health England (PHE and its predecessor organizations) established a radon laboratory to deliver services for radon measurements in homes and workplaces in the UK [1]. A key factor in developing these services was to set up stringent quality control and assurance protocols to enable the delivery of reliable and accurate results. There are nearly 40 checkpoints in the process, most exceeding 94% pass rate, starting from a quality check of poly-allyl diglycol carbonate (PADC) polymer and ending with a result modified by seasonal and occupancy correction factors. This work aims to show how to obtain the reliable results of radon measurements.
