Abstract Gamma spectrometry is a useful substitute for chemistry in the activation analysis of meteoritic specimens. After irradiation, instead of dissolving the sample and chemically extracting particular elements, the sample is instead placed in a scintillation counter and its gamma spectrum analyzed with the aid of a multichannel analyzer. By a suitable choice of irradiation conditions, various nuclides can be made to stand out clearly against the background of the irradiated meteorite. As examples, recent data are presented for aluminum and fluorine analysis of chondrites.
