Granules of high density polyethylene (PEHD) and low density polyethylene (PELD) were used in preparation of the mortar matrices in the immobilization process of radioactive waste materials containing Cs-137. Th, diameter of granulate forms varied from 0.2 to 2.0 mm. Four types of PEHD and PELD, forming four types of matrix materials, were used instead of ordinarily used stone granules of 2 mm average diameter, to decrease the porosity and density of the mortar matrix and avoid the segregation of stone particles on the bottom of the immobilized radioactive waste cylindric form. The physico-chemical characteristics of the radioactive waste mortar mixture form were improved, especially the radionuclide leach-rate. It decreased from 4% for the material prepared with stone granules to 2.5% to 3% for the materials prepared with PEHD and PELD. Mechanical strengths of the mortar-radioactive waste mixture samples prepared with PELD and PEHD were notably higher, 14 to 18 MPa, than the monoliths... prepared with the ordinary stone granules, 11 MPa. Using PEHD and PELD as granules in the radioactive waste mortar mixture, the weight of the final, full-sized immobilized monolith was up to 25% lower than material with stone granules.
