Abstract

A method of solidifying radioactive waste material in a stable mass by itself, characterized by the operations of mixing radioactive waste material with an aqueous urea-formaldehyde prepolymer, adding a curing agent capable of promoting the polymerization of said urea-formaldehyde to give a polymer capable of retaining a major proportion of said radioactive waste, in a form capable of resisting leaching by water, and stirring the resulting mixture until it solidifies.
