[The effect of ionizing radiation and calcium on plasma membrane structure].
Plasma membrane thymocytes were irradiated with doses of 10-10(4) Gy in the presence of 125 and 1125 mu mol of Ca2+ per 1 mg of membrane proteins. Fluorescence of 1-anilinonaphthalene-8-sulphonate and the degree of pyren eximerization were determined. The data obtained indicate that calcium can exert a stabilizing effect on the plasma membrane structure affected by radiation.
