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
Abstract 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.

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.

Natural Radioactivity (Radon-222) and Air Pollution Measurements in Washington, D. C.

Journal of Applied Meteorology, 1966
Abstract Atmospheric concentrations of radon (Rn222) were measured at urban, suburban and rural sites in the Washington, D.C., metropolitan area during a stagnant weather regime in mid August 1965. An analysis of air quality data, radon concentrations and meteorology indicates that the stagnant weather conditions which lead to the accumulation of smoke,

Effect of air pollution on element profile and radioactive compounds in six tree species

2021
Variation in macro and micronutrients and radioactivities (238U, 232Th, 137Cs, and 40K) due to air pollution was studied using six tree species: maple (Acer negundo), cypress (Cupressus arizonica) ash-tree (Fraxinus excelsior), pine (Pinus nigra), plane tree (Platanus orientalis), and poplar (Populus nigra). Tree leaf samples were collected in 2016 and

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 ...

The Effects of Ambient Air Pollution and Particle Radioactivity on Cardiovascular Health

2021
ABSTRACT Exposure to ambient air pollution is a well-recognized risk factor for cardiovascular morbidity and mortality. Studies have shown that air pollution, especially acute exposure to traffic and industrial sources, can influence the autonomic nervous system and in turn affect heart rate variability leading to arrhythmias.

Variations of stable (2H, 18O) and radioactive isotopes (3H, 14C) and chemical pollutants in air and precipitation

2000
In this paper we present our measurements of isotope concentrations (2H, 18O and 3H) in precipitation and 14C activity in atmospheric CO2, as well as concentrations of chemical pollutants (sulfur and nitrogen compounds) in precipitation and in air at two sites having different characteristics (Grič station in the Zagreb city area and the mountain ...
