Hot particles in industrial waste and mining tailings

摘要

Industrial waste was studied concerning its radioactive pollution. Using known properties of;the solid state nuclear track detector CR-39 we found among a high concentration of more or less homogeneously distributed single ct-tracks discrete spots of very high enrichments of cl-particles created by so called hot particles. We will. report about the alpha-activity, the concentration of hot particles and about their ability to be air borne. [References: 3]
