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.

The method for recalibration of thoron concentration reading of RAD7 and obtaining the thoron exhalation rate from soil surface [PDF]

Nuclear Technology and Radiation Protection, 2013
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.

Estimation of global radon exhalation rate distribution [PDF]

A radon exhalation rate distribution model was developed, which considers dependency on soil water saturation, soil temperature and soil texture. The global averages of the radon exhalation rates were calculated to be 17.5 and 18.0 mBq·m^{-2}·s^{-1} by ...

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.

Measurement of Radon Concentration Using SSNTD in Bartella Region

Al-Mustansiriyah Journal of Science, 2019
The alpha-radioactive inert gas Radon exhalation is associated with presence of Radium and its ultimate precursor uranium in the earth crust. Uranium decay deposits radon in soil, which is harmful on human and environment.

Efficacy and Safety of Acupuncture for Idiopathic Tinnitus: A Randomized Controlled Clinical Trial

International Journal of Clinical Practice, Volume 2026, Issue 1, 2026.
Objective The present study was designed to evaluate the effects and safety of acupuncture on idiopathic tinnitus. Methods A total of 74 participants (aged 18–60 years) with idiopathic tinnitus were randomly assigned to an observation group (OG) or a control group (CG) according to the treatment protocol, with 37 cases in each group.
