Growth of the Tritium Content of Atmospheric Molecular Hydrogen

Abstract

A SERIES of measurements of the abundance of tritium in atmospheric molecular hydrogen, covering the period 1956–58, were carried out by Gonsior in Germany1. These measurements were interpreted by him as showing that over that period the abundance was increasing linearly by 5 × 104 T.U. a year commencing with the ‘Castle’ series of thermonuclear weapon tests in the spring of 1954. (1 T.U. is equivalent to 1 tritium atom in 1018 hydrogen atoms.)
