AEROSOLS AS CARRIER OF NATURAL RADIOACTIVITY

Abstract

A description is presented of an apparatus for ionizing natural aerosol and for classifying the particles by mobility. The natural beta-activity of the particles is utilized as indicator. It was shown that particles with a radius between 1 and 15 x 10 to the minus 7th power cm carry 65% of the activity. No indications were found that a particular size classification of particles is preferred. Comparisons are made with similar measurements by Wilkening in New Mexico.
