Geographical Distribution of the Radioactivity of the Atmosphere

Abstract

Measurements of the natural radioactivity of the air have been made at several widely separated locations. On the average, radium products comprise from 50 to 90 percent of the total activity. Most locations exhibit a definite minimum during the year which may be associated with seasonal changes. Marked short-term variations were noted at all locations. No direct correlation between dust and nuclei counts was found at Washington D.C., where the radioactivity concentration appears to follow changes in the ground-level temperature and humidity.
