99mTc production on the basis of central generator and wasteless reactor Zr-Mo gel-technology

According to the current needs in production of 99Mo, the amount of radioactive waste from radiochemical processing of uranium targets can reach several tens millions GBq per year. The problem of management of long-lived radioactive wastes constrains the production of the radioisotope 99Mo by the uranium fission method. For developing countries, to which Belarus belongs too, such method of 99mTc production is inapplicable because of complexity, high costs and problems of utilization of high activity wastes. Recently, a simpler and less expensive method of 99mTc production based on the irradiation of the target from stable 98Mo has been developed. (orig.)
