THORON-SCOUT - first diffusion based active Radon and Thoron monitor

IOP Conference Series: Materials Science and Engineering, 2016
THORON-SCOUT is a stand-alone diffusion based active Radon and Thoron monitor for long term indoor measurements to evaluate the human health risk due to activity concentration in the breathing air. Alpha-particle spectroscopy of Po isotopes, being the progeny of the decay of the radioactive noble gas Radon, is applied to separately monitor activity ...

Back to Basics: Increasing Tiredness and Hunger in Nordic Classrooms and Their Links to Disorderly Behaviour and Academic Achievement

European Journal of Education, Volume 61, Issue 2, June 2026.
ABSTRACT This study examines trends in self‐reported tiredness and hunger among 4th grade students in the Nordic countries between 2016 and 2023, using data from PIRLS and TIMSS. Results show a significant increase in the proportion of students who frequently arrive at school feeling tired or hungry, with tiredness reported by 38%–52% of students and ...

Potential of Soils Natural Sorbents for Environmental Decontamination From 137Cs

Land Degradation &Development, Volume 37, Issue 2, Page 779-789, 30 January 2026.
ABSTRACT This study addresses the existing research gap concerning the lack of integrated data on the role of in situ soil components in the long‐term fixation of 137Cs under natural, protected, and non‐agricultural conditions. The contamination of ecosystems by radioactive isotopes, particularly 137Cs, represents a considerable environmental hazard ...

222Rn and 220Rn Levels in Drinking Water, the Related Health Implications, and Influencing Environmental Parameters in the Volcanic Area of Nkongsamba, Cameroon

Applied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
Radon (222Rn) and thoron (220Rn), both naturally occurring radioactive gases, are significant contributors to radiation exposure, posing risks such as lung and stomach cancer. This study assesses radon and thoron concentrations in drinking water sources within the volcanic region of Nkongsamba, Cameroon.

Assessment of Indoor Radon Exposure Risks in Relation to Dwelling Types in Gold‐Mining Communities of Akyempim, Wassa East District, Ghana

Indoor Air, Volume 2026, Issue 1, 2026.
This study investigated the effects of dwelling type, wall and floor coverings, radium‐226 concentration, soil moisture, and radon exhalation on indoor radon‐222 levels in the gold‐mining community of Akyempim, Ghana. Indoor radon was monitored using CR‐39 solid‐state nuclear track detectors deployed in 144 rooms across 21 sites for 90 days ...

Inertia in the response of radon monitors introduced by diffusion anti-thoron barriers

Journal of the European Radon Association, 2022
The reduction of thoron (220Rn) influence on radon (222Rn) monitors by diffusion barriers may cause some deterioration of the quality of the radon measurements.
