Measurement of Gas Fraction and Gas Permeability of Thawing Permafrost Caused by Climate Change

Earth's Future, Volume 14, Issue 3, March 2026.
Abstract Thawing of permafrost due to climate change is known to release gases such as the climate drivers carbon dioxide and methane, as well as the carcinogen radon. Gas permeability is extremely low in fully frozen permafrost and can be considered both to function as a seal preventing subsurface gases being released, and to prevent the creation of ...

Exposures in Indoor Air Affecting Health

Allergy, Volume 81, Issue 3, Page 700-719, March 2026.
ABSTRACT Indoor air quality (IAQ) is influenced by a wide range of chemical, biological and physical agents that can negatively impact physical, immunological and mental health. Adverse health effects depend on the type and concentration of pollutants, duration of exposure, and individual susceptibility.

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.
