title: Sister chromatid exchange frequency in human lymphocytes exposed to ionizing radiation in vivo and in vitro.
abstract: This paper reports statistically significant elevations in peripheral blood lymphocyte sister chromatid exchange frequencies in persons occupationally exposed to low levels of ionizing radiation when compared with unexposed persons. Low doses of X or gamma rays administered in vitro also produce significant elevations in sister chromatid exchange frequencies, though the magnitude of the increases is dependent upon culture medium and other factors.
