Radon transport to indoor air in groundwater plants as a by-effect of different water treatments
Journal of Water Process Engineering : 56 (Elsevier Ltd., 12.10.2023)Radon released from groundwater into indoor air is the main radiation safety problem for water treatment plants. This study investigated the release of radon from different water treatment processes and the effect of ... -
The Metrological Traceability, Performance and Precision of European Radon Calibration Facilities
International Journal of Environmental Research and Public Health : 20 (21.11.2021)The European Council Directive 2013/59/EURATOM requires that the EU member states introduce regulations for protection against radon exposure in homes and at workplaces [1]. In this context, the European metrology institutes ... -
Low-Level Radon Activity Concentration—A MetroRADON International Intercomparison
International Journal of Environmental Research and Public Health : 10 (10.05.2022)An international comparison of continuous monitors measuring radon activity concentration was performed to validate the traceability of the European radon calibration facilities. It was carried out by comparing the secondary ... -
Testing of thoron cross-interference of continuous radon measuring instruments
Journal of the European Radon Association : 3 (European Radon Association, 04.03.2022)Thoron (220Rn) may interfere with radon (222Rn) measurements, if present. We measured the thoron cross-interference (CI) signal of nine types of electronic radon instruments in constant thoron concentration without the ... -
Natural radioactivity of residues from groundwater treatment facilities in Finland
Journal of Radiological Protection : 43 (IOP Publishing Ltd., 12.09.2023)The accumulation of naturally occurring radionuclides in solid residues was investigated from groundwater treatment facilities (GTFs) in Finland. Natural radionuclides U-238, Ra-226, Pb-210 and Ra-228 were found in various ... -
Regulatory control of naturally occurring radioactive material (NORM) in the Nordic countries : Report from working group Nordic NAT
Nordic Radiation and Nuclear Safety Series : 03:2023 (The Swedish Radiation Safety Authority, 21.08.2023)Radiological risks associated with naturally occurring radioactive materials (NORM) have been fully recognized in recent decades, and hence, resulted in the integration of NORM radiation protection requirements within the ... -
Radon Exposure Concentrations in Finnish Workplaces
Health Physics : 125(2) (Wolters Kluwer Health, Inc. on behalf of the Health Physics Society, 08 / 2023)The aim of this study was to obtain information on the radon concentrations to which Finnish workers are exposed. Radon measurements were conducted as integrated measurements in 700 workplaces, supplemented by continuous ... -

A methodology for the systematic identification of naturally occurring radioactive materials (NORM)
Science of the Total Environment : 881 (Elsevier B.V., 05.04.2023)Naturally occurring radioactive materials (NORM) are present worldwide and under certain circumstances (e.g., human activities) may give radiation exposure to workers, local public or occasional visitors and non-human ... -
Radioactivity of residues from waste incineration facilities in Finland
Journal of Radiological Protection : 43 (IOP Publishing LtdThe Society for Radiological Protection, 06.04.2023)Waste incineration in Europe has been increasing in the past few decades as there is a need to reduce the burden on landfills and their associated environmental concerns. While incineration reduces the volume of the waste, ... -

Improving the Assessment of Occupational Exposure to Radon in Above-Ground Workplaces
Radiation Protection Dosimetry : ncab127 (Radiation Protection Dosimetry, 26.08.2021)Representative sampling of radon in indoor air is difficult because the concentration often exhibits unpredictable spatial and temporal variation. In workplaces, temporal variation may be rapid, and the minimum and maximum ... -
