摘要：

Results of analysis of cosmogenic radionuclides (57,58,60Co, 54Mn, 46Sc, 22Na, 48V and 26Al) in fragments of the Košice meteorite are presented and discussed. Analyses were carried out using a low-level HPGe-spectrometer placed in a lead-iron-copper shield. Twelve meteorite fragments were available for the analysis with masses from 27 to 2,163 g. The lowest massic activities were observed for 46Sc (down to 0.1 mBq/g), and the highest for 22Na (up to 2 mBq/g). The measured radionuclide activities showed differences between fragments, as indicated mainly by the 60Co data, which were caused by different positions of meteorite fragments from the center of the meteorite body.
