The time of cell destruction was determined by pedigree analysis before macrocolony formation immediately after irradiation of gamma rays (400-900 R) in cultured rat hepatoma cells. Cell destruction occurred and was distributed to various generations

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

Analysis of Sr and measurements of radioactivity of 90Sr were made on bones obtained from 43 leukemic patients at autopsy performed over a period from 1962 to 1965 at the Department of Pathology, Tohoku University School of Medicine. The quantity of

Life span of adult Sarcophaga peregrina became short after X-irradiation given in early pupal stage. It also inhibited imago formation of irradiated pupae. Shortening of life was adequately explained by upward shift of age specific mor-tality curve.

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

It is generally believed that the Cell loss of a growing population does not take place immediately after irradiation but cell death is preceded by cell divi-sions for several generations. In the present study a simple theory is advanced in which the
