title: Control over the cosmic radiation level during flight of space vehicles Vostok 3, Vostok 4, Vostok 5 and Vostok 6.
abstract: 1. During the flights of the"Vostok"series of spaceships the radiation conditions in space were kept under operative control which comprised: a. The solar activity observation and forecasting of the solar flares followed by the appearance of proton fluxes in the near space. b. Probing the upper atmosphere with the help of balloon launchings at high altitudes. c. Direct measuring radiation level inside the "Vostok" spaceships. 2. The radiation dose received by the cosmonauts during the flights of the "Vostok" spaceships is given. Contributions of various components of cosmic radiation are considered. 3. The possibility of flights of the "Vostok" series of spaceships at high altitudes is evaluated.
