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.

Beyond Upper Airway Involvement: Evidence of Intrinsic Lung Disease in a Mouse Model of Mucopolysaccharidosis I

Journal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
ABSTRACT Almost all patients with mucopolysaccharidosis (MPS) develop respiratory dysfunction of varying severity during disease progression. While respiratory disease in MPS has traditionally been attributed to upper airway obstruction caused by glycosaminoglycan (GAG) accumulation in the trachea and bronchi, involvement of the intrapulmonary ...

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 ...

Soil Radon Exhalation Rate as a Function of Rainfall and Soil Suction Pressure

, 2004
It was been found that the contents of water in soil played a significant role in the rate of radon exhalation. Soil suction pressure, which is related to water content, is also related to radon exhalation rate.

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 ...

Modeling of radon exhalation from soil influenced by environmental parameters.

, 2018
Atmospheric radioactive noble gas radon (Rn-222) originates from soil gas exhaled in the atmospheric surface layer. Radon exhalation rates from soil as well as corresponding meteorological and soil parameters were recorded for two subsequent years. Based
