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.

Inequality in Burden of Tracheal, Bronchial, and Lung Cancer Attributable to Residential Radon Exposure: Global Analysis and Country‐Level Patterns in High Granite/Marble Consuming Countries

Indoor Air, Volume 2026, Issue 1, 2026.
Backgrounds Radon is the second leading cause of lung cancer, accounting for 3%–14% of cases worldwide. Aim To assess global and national trends in tracheal, bronchial, and lung (TBL) cancer attributable to residential radon from 1990 to 2021 and to project trends up to 2046. Methods The Global Burden of Disease (GBD) 2021 data were utilized to analyze
