Sergey Vernov

Sergei Nikolaevich Vernov was a Russian-Soviet physicist who pioneered the study of primary cosmic rays. He examined cosmic rays initially with high altitude balloons, then with ground observatories and then in space and found patterns in the distribution of ions in latitudinal belts and radiation belts at varying altitudes. Although he was the first to identify these radiation belts, they are better known in the Anglophone scientific world through the work of James van Allen and termed as Van Allen Radiation Belts.
