Section: claims

1. A method of entrapping the hazardous components of moisture-bearing low-level radioactive and mixed waste material which comprises the steps of: selecting an encapsulating material from the group consisting of polyacrylic acids and the salts thereof;  determining the amount of encapsulating material which is required to form a gel-like matrix with the waste material; and  blending the encapsulating material with the moisture-bearing waste material to react the encapsulating material with the moisture in the waste material until a gel-like matrix is formed which entraps the hazardous components of the waste material and provides a final waste material product having no freestanding liquids. 2. A method according to claim 1 wherein the encapsulating material selected is polyacrylate. 3. A method according to claim 1 wherein said encapsulating material is placed within a pressurized vessel and blended with said moisture-bearing waste material by being discharged from the vessel into the moisture-bearing waste material.
