Identification of Cosmic Matter from the Ratio of Contents of Cosmogenic and Natural Radionuclides

摘要

We considered the possibility of revealing the cosmic nature of an object by determining the content of cosmogenic and natural radionuclides in it by a low-background gamma-spectrometric complex. The results of studies of the Lost City and Kaidun meteorites and for lunar soil are presented. Three samples of unclear genesis were analyzed and their terrestrial origin was revealed.
