Quality assurance in radon SSNTD measurements : PHE experience

105--110

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.

In recent years a large number of radon intercomparison exercises has been organized; most of them took place in radon chambers, in reference atmosphere of the parameter to control (i.e. radon gas) under temperature, humidity and atmospheric pressure stable conditions. In 2014, in the tunnel belonging to the Lurisia spas complex (Lurisia, Piedmont, Italy), with natural high concentrations of uranium and radon gas, an intercomparison exercise has been held to give to radon measurement services and laboratories the possibility to test their passive systems under field conditions, which are less controlled and much more challenging. The response of laboratories was very positive: 46 participants from 10 European countries and 3 non-European countries. Generally about 80% of results of participants were considered acceptable even if it was observed a global trend of a substantial underestimation of the actual radon concentration.
