Return to an extreme environment exposure after pulmonary infection: SCUBA diving as a model?
Physiological Reports, Volume 14, Issue 7, April 2026.Graphical overview of the experimental protocol used to investigate post‐COVID physiological responses during scuba diving at three different depths. Abstract The human body implements several adaptive mechanisms to perform in extreme environments. Increasingly, individuals return to such conditions after pulmonary infections, raising concerns about ...

Journal 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]
Nuclear 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.

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.
