Abstract:

The effects of such factors as concentration, pH, etc. on the luminescence efficiency of biological compounds in aqueous solutions under high-energy radiation bombardment were studied. The results indicate that biological compounds quench the distilled-water solvent luminescence that there is increased luminescence quenching with increasing concentration and that two of the compounds studied, tryptophane and glutathione, show a dependence of luminescence on the pH of solutions. These results are discussed briefly in terms of theoretical considerations of energy transport mechanisms in irradiated solutions. Author
