Physical and Radiobiological Investigations on Artificial Earth Satellites

The monograph presents experimental materials obtained on Earth orbiting space ships and data from the literature, summarizing physical and biomedical research in space. Results of research concerning the radiation environment in orbits of Earth orbiting space ships are presented. The principles of calculation of permissable radiation doses are given and physical protection of space ships is discussed. Radiation dangers are evaluated, using the permissable levels of cosmic radiation for man and other bio-objects. Results are presented of experiments involving the study of combined effect of radiation and other factors of space flight on animals, higher and lower plants, unicellular organisms and simulated biochemical systems.
