nonirradiated cells exposed in vitro to irradiated serum ( 15 min postirradiation ) exhibited a 36- to 48-fold increment in hyperdiploidy ( p = 0.0001 ) and a 2.- to 2.2-fold rise in chromatid gaps and breaks ( p less than 0.01 ) , but none of the chromosome-type aberrations seen in cells exposed to radiation .
