Scientific paper

Certain anomalous variations in galactic-cosmic-ray intensity observed in the solar system over the period from 1971 to 1974 are investigated by studying the radioactivity of the Gorlovka stony meteorite, a group H chondrite which fell in 1974 and is similar in chemical composition to the Pribram and Lost City objects. Measured activities of the cosmogenic radioisotopes Sc-46, Mn-54, Na-22, Co-60, and Al-26 as well as the natural radioisotope K-40 in a Gorlovka specimen are compared with calculations of the equilibrium activities of the same isotopes within chondrites of different sizes having the same composition as Gorlovka. The sizes of the meteoroid and its orbit are derived, and the measured radioactivities are used to establish the nature of the spatial variation in galactic-cosmic-ray intensity.
