The “PHOENIX” Space Experiment: Study of Space Radiation Impact on Cells Genetic Apparatus on Board the International Space Station

The preliminary results of the 1st session of Russian "PHOENIX" long-term space experiment are presented. The survival of dried human lymphocytes and mouse bone marrow cells in 199 days space flight is studied. The degree of DNA fragmentation is analysed for samples flown in different ISS compartments. It is shown that biological data correlates with the results of space radiation dose measurements.
