The Oslo Meteorite Research for Cosmogenic Radionuclides and The Interpretation of The Results

Abstracts

EN

Nondestructive high-resolution gamma spectrometry techniques were used to measure cosmogenic radionuclides in 32.5g fragment of Oslo meteorite which the fall was not observed. Five radioisotopes with half-lives ranging from 278.1 days to 7.17´105 years have been detected. The signals observed for 26Al, 22Na, 54Mn, 57Co and 60Co were interpreted in terms of the meteoroid depth profiles and terrestrial age after the fall. The pre-atmospheric radius of the chondrite was estimated to be >100 cm. Concentrations of short-lived nuclides limits the fall date before December 2011.
