Biological Effect of Space Radiation Simulated at Ground Base Plasma Facility

M V Roshan*, Nadia Vahdat R

Schemed with high repetition rate, the plasma focus device promises to simulate the radiation environment and analyze the biological effects on cells. The most radiation-sensitive site within the cell, DNA, could be irradiated by 110 j proton beams at high operation frequency. Such plasma device if operated at 1 Hz repetition rate produces ten Double-Strand breaks, DSB, per second. The surviving fraction of the DNA is likely to be more affected by higher dose frequencies.
