Trynitite is a material in form of a glass created as a result of a nuclear explosion close to ground. The mechanism of its formation is similar to the formation of impact glasses and tektites, although the material usually contains trapped bubble voids, much more water and it is radioactive. High resolution non-destructive gamma spectrometry technique was used to measure rdionuclides in the chips of trinitities. The signals were detected for 137Cs, 152Eu, 226Ra, 241Am and 133Ba. The most extreme concentration was found for cesium 137Cs which the specific activity reached the level of 2317 mBq/g. Much lower values were obtained for 241Am – 722 mBq/g, 152Eu – 211 mBq/g, 226Ra – 451 mBq/g and 133Ba – 94 mBq/g.

Cosmogenic radionuclides in meteoroids are produced in space in the process of activation. These nuclides have various lifetimes in range from a few days to several hundred thousand years and can therefore be helpful in solving several problems related to the study of meteoroids and their remains, both in space and on the Earth. The simplest application of cosmogenic radionuclide decay in meteorites is to determine the terrestrial age of meteorites, especially those whose fall has not been observed. In this article, we present an additional application of cosmogenic radionuclide measurements, namely for the verification of origin of rocks that show equivocal features and may potentially represent meteorites.
