Abstract
Radioactive organic liquids are converted to a form suitable for burial by the process wherein the liquid is contacted with insoluble, swellable polymer particles to form swollen gelled particles which are dispersed in an unsaturated polyester, vinyl ester resin or mixture thereof which is then cured to a solid state with the gelled particles encased therein.
Claims7
A process for encapsulating low level radioactive liquid water-insoluble organic wastes into a solid form suitable for burial which comprises contacting one part by weight of said waste with less than one part by weight of a particulate, cross-linked, organic liquid-swellable, organic liquid-insoluble polymer to provide discrete, non-coalescent, gelled particles of said polymer and said waste;
- dispersing 0.1 to 3 parts of said gelled particles essentially uniformly in one part of a curable liquid resin selected from the group consisting of unsaturated polyesters, vinyl ester resins or mixtures thereof and curing said liquid resin to a solid with said gelled particles encased therein.
