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.

Level of Radon Exhalation Rate from Soil in Some Sedimentary and Granite Areas in China [PDF]
An investigation of radon exhalation rate from soil by using a 'closed-can' method with activated charcoal absorption on a small scale has been carried out to determine the radon exhalation rate of about 144 samples from sedimentary and granite

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 ...

The method for recalibration of thoron concentration reading of RAD7 and obtaining the thoron exhalation rate from soil surface [PDF]
Thoron exhalation rate can be obtained through the combination of the “accumulation chamber” technique and RAD7. Thoron’s rapid decay causes the intake path and the air flow rate to become important factors in calibration.

Exploring atmospheric exchange with natural tracers [PDF]
This study is focused on the application of radon (222Rn; half life time of 3.82 days) as an atmospheric tracer for evaluating the exchange of trace compounds between the land surface and the atmosphere and for understanding atmospheric mixing processes.

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
