Native protein excited by low doses of γ-radiation serves as a source of secondary biogenic radiation

In is demonstrated that native protein of egg-white after being γ-irradiated with law doses is able to stimulate transition of cells of remote biological detector from non-cycling state to proliferation even if irradiated protein is separated from detector by quartz-glass. Animal tissues which have a high protein content (freshly cut hair, insect bodies) reveal the same ability. The role of natural background radiation in the maintenance excitation, state of living tissue proteins is discussed. 13 refs.; 1 figs.; 4 tabs
