Abstract
ABSTRACT Chemical and hydrodynamic processes leading to accumulation of radioactive scales on technological equipment as well as their chemical, radiochemical and isotope composition are considered. Radioactive wastes that accumulate in a considerable volumes in the oil-field objects such as gathering and sedimentation tanks as well as sand collectors are also investigated. Principal ways of radioactive contaminated materials treatment are offered. Radio-active scales on technological oil producing and desalting - dewatering equipment and radioactive wastes are represented with insoluble sulfates of Ra226, Ra228 isotopes and products of their decay. As the larger radioactive contaminated wastes volumes, the higher their disposal costs the technologies goal is to minimize waste volume. The technological processes includes two stages: separation of hydrocarbons and water for further use, from the mineral part,extraction of radioactive elements compounds from the mineral part. This part of radioactive wastes should be disposed and its volume is not higher than 1.0 - 1.5 % of the initial waste volume. Specific activity of recovered hydrocarbons, water and remaining mineral part does not exceed safe level.
