Effect of Mixed Gamma-Neutron Radiations on the Spectral Absorption of Indocyanine Green

摘要

Blood from beagles and aqueous solutions of indocyanine green were separately irradiated with mixed gamma-neutron radiations at five doses from 0.53 to 48 kilorads. The light absorption of the irradiated dye in combination with irradiated blood was characterized. In addition, unirradiated dye was mixed with irradiated blood and similarly studied. The shape of the absorption spectrum was the same for all samples; the absorptivity of unirradiated dye was unaffected by mixing with irradiated blood; and the absorptivity of irradiated injectable solutions (5 mg/ml) was unchanged.
