Assessment of137Cs contamination of combustion products and air pollution during the forest fires in zones of radioactive contamination

Radioprotection, 2017
The results of the investigation of radiation hazard of forest fires in the radioactive contaminated areas in the article are presented. The activity concentration of long-lived radionuclides in forest fuel materials is shown. Airborne concentration of 137 Cs produced by the combustion of forest fuel materials with different contamination density can ...

Ventilation and air pollution studies using radioactive tracers. A critical review

The International Journal of Applied Radiation and Isotopes, 1977
Abstract The use of radioactive tracers for ventilation and air pollution investigations is critically reviewed and future trends are analyzed. The use of 85 Kr for ventilation studies is expected to increase steadily because the methods are proven to be simple, accurate and safe.

Specific features of the ionization of atmospheric air resulting from radioactive pollution

Technical Physics, 2000
Specific features of inhomogeneous ionization resulting from radioactive pollution in the lower atmosphere are investigated. A model of track ionization of air is proposed that allows for such elementary processes as kinetics, molecular diffusion, and drift of ions in an electric field. The applicability limits of the model are determined.

A Discussion on recent research in air pollution - Interhemispheric transfer of radioactive pollution from nuclear explosions

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1969
By using a simple model of the atmosphere, having two compartments, it is possible to derive expressions for the fission product reservoirs of the northern and southern hemispheres as functions of the gross rate of exchange between hemispheres, and the fallout rate. When observed values (1963—6) of the fission products are inserted into the theoretical

Overproduction of TNF-α and lung structural remodelling due to chronic exposure to volcanogenic air pollution.

Chemosphere, 2019
Volcanogenic air pollution studies and their effects on the respiratory system are still outnumbered by studies regarding the effects of anthropogenic air pollution, representing an unknown risk to human population inhabiting volcanic areas worldwide ...
