[Changes in the chromosome map of mouse lymphosarcoma cells with prolonged irradiation]

In experiments on lymphosarcoma cells LS/BL, a study was made of changes in the chromosome pattern after long-term continuous irradiation at a low dose rate (35.8 X 10(-5) mC X kg-1 X s-1). To ensure reliable detection of changes in the chromosome length the method of automated computer analysis of the chromosome pattern with subsequent statistical evaluation was used. The radiation effect was manifested by a higher frequency of shape abnormalities in continuously exposed cells.
