Soviet scientists claimed to have discovered the third radiation belt around the earth and published such findings two years before the findings of EXPLORER XII were made public by NASA on January 19, 1962. Academician Blagonravov, Vice President of the International Committee on Space Research, said in an Izvestia interview that the existence of a dense belt with energies of 200 to 20,000 electron volts at a distance of 25,000 to 50,000 miles was recorded by Soviet space launchings in 1958. Such findings, he said, were published by Dr. K. Gringauz and associates in the February and April issues of the Soviet Academy of Sciences Proceedings in 1960, and in later publications. Commenting on the view that the three radiation belts really formed a single large pulsating band that might be called a "magnetosphere," Blagonravov agreed that the boundaries might be arbitrary but that the charged particles in each belt had distinctive characteristics and that it would be "inexpedient" to reject the theory of three belts.
