Chicken embryos in fibroblast media exposed to gamma -radiation of Co/ sup 6//sup 0/ show a lowering and at higher doses a complete suppression of mitotic activity. For a detailed study, the growth of the epithelium was investigated, exposing the cultures to gamma -radiation ranging from 100 to 200,000 r at the incubation temperature of 37.5 to 38 deg C. As a result of the radi ation, especially at higher integrated doses, the growth of the epithelium was inhibited and the appearance of non-ho mogeneous growing tissue has been observed. Another effect of the high-level radiation consisted in the dilution of the medium and the breakdown of the integrity of the membrane's cells leading to the loss of their mobility. The behavior of the epithelium was found to be similar to that of intermuscular tissue. (TTT)
