Observations of the Emission of Light on Dissolution of Irradiated Solids in Certain Liquids

Nature volume 188, pages 395–396 (1960)Cite this article

Abstract

Ahnström and Ehrenstein have observed the emission of light on dissolution of some organic solids in water1. We have been concerned with measurements of stored radiomimetic energy in solids treated with ionizing radiation. This problem has been approached partly by dissolution in liquids typical for dosimetry by the methods of radiation chemistry and partly by attempts to excite, during dissolution, liquid scintillators2. Some results of the latter kind will be summarized here. Most of the experiments were concerned with fine-grained sodium chloride which was given doses up to 200 Mrads of cobalt-60 γ-radiation and 2-MeV. electrons from a Van de Graaff machine.
