Technical Report ·
OSTI ID:4035441

A quantitative evaluation of the effects of small radia tion doses on heredity in humans was made by considering the amount of epithelium and fragments in anaphase and telophase mitosis in chromosome recombinations. Tissue cultures were prepared from 1.5- and 2-month old human embryos irradiated by 10, 25, and 50 r. The data show a higher radiosensitivity than expected. The frequency of spontaneous chromosome recombination was 1.5%; with an exposure to 1 r it was 0.25%. Hence, the frequency of natural chromosome mutation was doubled at about 6 r. (R.V.J.)
