Radon exhalation rates corrected for leakage and back diffusion – Evaluation of radon chambers and radon sources with application to ceramic tile

open access: yesJournal of Radiation Research and Applied Sciences, 2014
The natural radon decay, leakage and back diffusion are the main removal processes of radon from its container. Ignoring these processes leads to underestimate the measured value of radon related parameters like exhalation rate and radium content.

Radon-thoron measurements in air and soil from some districts of northern part of India [PDF]

open access: yesNuclear Technology and Radiation Protection, 2015
Radon, thoron and their progenies in the indoor environment are considered as one of the health hazards. The alpha emitting nature of these gases made it possible to detect in indoor environment with the help of nuclear track detector techniques.

Exposures in Indoor Air Affecting Health

open access: yesAllergy, 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.
