EFFECT OF SOFT X-RAYS ON THE LUMINESCENCE EFFICIENCY OF BIOLOGICAL COMPOUNDS

Abstract

This report involves the study of the luminescence efficiency of different biological compounds under high-energy gamma bombardment before and after 50 kv x-irradiation. After x-irradiation some compounds (crude catalase) showed no change; in other compounds (ascorbic acid) luminescence increased; and in others (glutathione) luminescence decreased. Parallel measurements made on the luminescence changes and chemical changes of the solute indicate that the luminescence curve does not follow closely the decomposition curve. These studies illustrate the influence of the radiation induced decomposition products and are of importance in considering biological reactions induced by ionizing radiation.
