From 15th plenary meeting; Madrid, Spain (10 May 1972). In modelling the action of the high energy component of space radiation in a space ship, the secondary radiation resulting from the interaction of 76 GeV protons with a target was used. The radiation flow consisted of neutrons, mesons of different kinds and charges, protons, and gamma-quanta of wide energy spectrum. We studied the influence of radiation on the survival of E. coli B and T4Br/sup +/ bacteriophage; on the growth, dry weight, and survival of Vicia faba; on the frequency of chromosome aberrations and number of cells with abnormal mitoses; on the rate of postirradiation recovery acconding to these characteristics; and also on the yield of the r-mutants of T4Br/sup +/ bacteriophage, their distribution and biochemical identification.
