Cultured hepatoma cells of the rat were irradiated with 400 to 900 R of gamma-rays. They were kept at room temperature for several hours before transferred to normal culture condition at 37 degrees C. The pedigree analysis of growing cells recorded b

Cultured rat hepatoma cells were irradiated with 500 to 800 R of gamma rays and inhibition of cell growth was recorded on cinemicrograms. Analysis of constructed pedigrees of control and treated cells indicated that (1) usual type of frequency distri
