The Study of the Concentrations of Long-Duration Radioactive Aerosols of Atmospheric Air in Its Relation to the Amount of Dust

摘要

It is well known that an increase in the concentration of atmospheric dust containing stable isotopes can lead to a decrease in the specific activity of dust hovering in the air. In the given case, stable atmospheric dust appears in the roll of a factor which reduces the amount of radioactive substances in the atmosphere of air. Since it is necessary to take this condition into consideration in the hygienic evaluation of the radioactive contamination of the atmospheric air, experiments were carried out to determine the concentration of long-duration radioactive substances and dust of the atmospheric air in Moscow.
