“…The Ionizing Radiation Metrology Laboratory (LMRI, IFIN-HH, Romania) has developed this facility in the framework of national and European joint research projects [14]. The chamber is cylindrical in shape, with a volume of 1 m 3 and has accessories used to produce radon reference atmospheres They ensure international metrological traceability and equivalence of radon activity measurements, while performing reliable measurements of radon activity concentration.…”

Since 2020 a large consortium has been engaged in the project EMPIR 19ENV01 traceRadon to develop the missing traceability chains to improve the sensor networks in climate observation and radiation protection. This paper presents results in the areas of: Novel 226Ra standard sources with continuous controlled 222Rn emanation rate, radon chambers aimed to create a reference radon atmosphere and a reference field for radon flux monitoring. The major challenge lies in the low activity concentrations of radon in outdoor air from 1 Bq∙m-3 to 100 Bq∙m-3, where below 100 Bq∙m-3 there is currently no metrological traceability at all. Thus, measured values of different instruments operated at different locations cannot be compared with respect to their results. Whin this paper, new infrastructure is presented, capable of filling this gap in traceability. The achieved results make new calibration services, far beyond the state of art, possible.

Radon gas is the largest source of public exposure to naturally occurring radioactivity. Radon activity concentration maps, based on atmospheric measurements, as well as radon flux maps can help Member States to comply with the EU Council Directive 2013/59/Euratom and, particularly, with the identification of Radon Priority Areas. Radon can also be used, as a tracer, to improve Atmospheric Transport Models and to indirectly estimate greenhouse gas (GHG) fluxes. This is important for supporting successful GHG mitigation strategies. One approach to estimate GHG fluxes on local to regional scale is the socalled Radon Tracer Method (RTM), which is based on the night-time correlation between atmospheric concentrations of radon and GHG measured at a given station together with information on the radon flux data within the station footprint. Thus, atmospheric monitoring networks are interested or are already measuring atmospheric radon activity concentrations using different techniques but a metrological chain to ensure the traceability of all these measurements was missing.Since 2020 a large consortium engaged in the project traceRadon [1] to develop the missing traceability chains to improve the respective sensor networks http://traceradon-empir.eu/ . This paper presents results in the areas: Novel 226 Ra standard sources with continuous controlled 222 Rn emanation rate, radon chambers aimed to create a reference radon atmosphere and a reference field for radon flux monitoring. The achieved results are making new calibration services far beyond the state of art possible.

“…The published articles are intended to provide guidance and solutions for correctly measuring and evaluating radon in different environments and the efficient management of radon levels in affected buildings for radiation protection of the population. An attempt has been made to classify the contributions below [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]:  Three papers aim to define radon awareness and policy perspectives, to set-up radon specific norms to control of the health risk of radon exposure in the Republic of Moldova and to better define measurement procedures, approaches and standard guidelines for Romanian Schools.…”
