Open the CIPO recordAbstract From the Canadian patent
A novel technique for encapsulating and immobilizing low-level radioactive liquid wastes involves formation of an oil-in-water emulsion, encapsulation of the individual oil droplets by interfacial condensation and subsequent incorporation of the encapsulated oil suspension into a curable polyester resin. Stable and strong wasteforms may thus be produced containing up to about 40% by volume of entrapped oil.
