CHEMICAL LUMINESCENCE OF LUMINOL UNDER THE EFFECT OF IONIZING RADIATION, AND ITS INFLUENCING BY MEANS OF ANTIRADIATION AGENTS
ARMY BIOLOGICAL LABS FREDERICK MD
Pagination or Media Count:
Under the influence of X-rays, an aqueous solution of luminol exhibits a marked chemical luminescence. Consideration is given to an indirect radiation effect. It is highly dependent on the concentration in the concentration range of 0.01-0.1. It is linked to the presence of oxygen and can be weakened by cysteine in concentrations corresponding to the biologically effective concentrations. The radiation-induced chemical luminescence is independent on the temperature and takes place with the same intensity in the ice phase, hence it is independent of diffusion processes. An energy transport through electron displacements in the water phase is discussed. By contrast, the protective effect of cysteine is temperature-dependent and is lost upon freezing. Protective effect against radiation is exhibited by cysteamine, cysteine and glutathione. Cystamine, histamine and KCN are ineffective.
