On the radioactivity of the Bruderheim chondrite

Abstract

A sample of the Bruderheim chondrite (fell March 4, 1960) was examined with a gamma -ray spectrometer, K/sup 40/, Al/sup 26/, Mn/sup 54/, and Na/sup 22/ having been identified and quantitatively assayed. The concentrations found were 0.089% K, 57 disintegrations per minute per kilogram Al/sup 26/, 82 disintegrations per minute per kilogram Mn/sup 54/, and 90 disintegrations per minute per kilogram Na , which are in good agreement with values found by other workers for this and other meteorites.
