Approved For Release 2009/01/05: CIA-RDP80T00246AO05400350004-0 S.N.VERNOV A.E.CHUDAKOV STUDY OF COSMIC RAYS BY ROCKETS AND SPUTNIKS' IN THE USSR In the USSR study of cosmic rays by rockets was started in 1947. In the beginning, with the help of Geiger counters the number of charged particles was measured, and formation of the electron-photon component in the interaction of primary particles of cosmic rays with nuclei of light elements was investigated. It was shown that in 1947,1948,1949 and 1951 the intensity of cosmic rays, at the altitudes up to 75 km, was the same and didn't change more than by 5%, In 1949 the data on the photon intensity outside the atmosphere were obtained...
