The cytogenetic characteristics of Lactuca sativa lettuce seeds exposed in a package located inside the Bion-M1 biosatellite were studied. The absorbed dose according to solid-state dosimeters placed inside the package was 58 ± 3 mGy. There was a significant (p ≤ 0,001) increase in the percentage of cells with chromosome aberrations, cells with multiple aberrations, as well as the percentage of chromosomal bridges and fragments; the percentage of chromatid bridges and fragments was not significa
