Fallout radionuclides and beryllium-7 in over-ocean aerosols

Abstract

Particulates in surface air over the Atlantic Ocean were collected on air filters for several months during each year from 1964 to 1966. Measurement of the radioactivity in these filters was by gamma-ray spectrometry, and the concentration of various fallout nuclides, and Be⁷, determined by computer analysis of the spectra. Comparison of over-ocean, over-land concentrations of radioisotopes in surface air is discussed.
