The fresh-fallen Kunya–Urgench H5 chondrite was studied in various aspects including natural and induced (X-ray and γ-ray) thermoluminescence, tracks of VH nuclei, and cosmogenic radionuclides with different half-lives. The experimental data, comp

The paper presents data obtained on the production rates of cosmogenic radionuclides of different half-life in 42 chondrites that fell in 1959–2016. A quantitative approach is developed for using cosmogenic radionuclides as natural detectors of gal

Cosmogenic radionuclides with half-life periods T1/2 ranging from several days to a million years, produced in the nuclear reactions of galactic cosmic rays (GCR) with meteoritic matter, provide valuable information on the GCR intensity variations on

The results of long-term studies of cosmogenic radionuclide production rates along the orbits of 39 chondrites that fell to the Earth between 1959 and 2013 are presented. They constitute a long series of homogeneous data, a statistical smoothing of w

Cosmogenic radionuclides produced by galactic cosmic rays (GCR) in meteorites during their motion in space are natural detectors of the GCR intensity and variations along the meteorite orbits. On the basis of measured and calculated contents of cosmo

Based on the example of the measured and calculated contents of cosmogenic radionuclides in freshly fallen Chelyabinsk and Kosice chondrites, an indirect approach to studying variations in galactic cosmic rays is presented that uses variations in the

The isotopic anomalies of some extinct radionuclides testify to the outburst of a nearby supernova just before the collapse of the protosolar nebula, and to the fact that the supernova was Sn Ia, i.e. the carbon-detonation supernova. A key role of sp
