| Popis: | where dA(t) is the change in A resulting during a Purpose: To estimate the frequencies of dicentric chromosomes in time interval dt from the rate of induction, I(t), and peripheral lymphocytes of astronauts on missions to Mars. the rate of losses, L(t), of aberrant cells. In peripheral Materials and methods: Calculations of expected frequencies of lymphocytes, dicentrics are lost during time after dicentrics are based on dose estimations and lymphocyte biology. irradiation either by cell death and renewal from Results: Frequencies of dicentrics are predicted to be 10‐40 times higher than the background level. |
