The potaesium concentration in various meteorites was determined by means of the neutron activation with the reaction K/sup 41/(n, gamma )K/sup 42/. The high sensitivity of the method permits, inaddition to the determination of the potassium content of chondrites, the measurement of the very small potassium contents in some achondrites. The very low potassium content of some iron meteorites could be measured with sufficient accuracy. Whereas in the stone meteorites the total potassium concentration could be calculated easily from the messured K/sup 41/ msss on the basis of the frequency of the 41 isotope (6.8%), such an indication of the total potassium concentration in some iron meteorites was not possible since the measured K/sup 41/ mass was so low that it must be assumed that considerable masses or almost all the Mi arose on the basis of the effect of cosmic radiation on the iron core of the meteorite. the values obtained were interpretated as the limiting value for the K/sup 41/ produced by cosmic radiation.
