Metrology for radon monitoring

Short Name: MetroRADON, Project Number: 16ENV10
Radon Test Kit

New radon measurements will enable regulators to reliably assess and limit public exposure

Radon is estimated to cause between 3 % and 14 % of all lung cancer cases, depending on the average radon level in the country - in Europe, this corresponds to around 15,000 to 20,000 deaths every year. Over the coming years, as part of the new EU Basic Safety Standards (BSS) Directive, public exposure to radon will become part of legal metrology in Europe. All member states will be required to demonstrate that levels of radon activity concentration do not exceed 300 becquerels per cubic metre. To achieve measurements at this low level, new calibration procedures for existing commercial radon monitors must be developed.


This project has provided traceable measurement and calibration resources for the monitoring of radon, which enables regulators to meet the new requirements and support implementation of the new EU-BSS across Europe. Improvements in the reliability of radon measurements resulting from the project will provide a better basis for the development of effective strategies to mitigate and prevent the serious health effects of this pollutant.


This project builds on from EMRP project ENV57 MetroERM.
