Large volume Ge-detectors have been used for the analysis of positron emitters of cosmogenic origin in extraterrestrial samples including lunar samples and meteorites. We present results from the analysis of Al-26 in the Rumanova chondrite which was found in 1994 in Slovakia. A slide of the meteorite was cut into similar to 1 cm(3) cubes which were analyzed in a coincidence Ge-NaI(Tl) spectrometer placed in a large shield measuring 1.5 x 1.5 x 2 m(3), and consisting of iron, lead and copper layers. Operational characteristics of the spectrometer are presented and discussed, as well as the Al-26 profile observed in the meteorite.
