... Abstract Processes of oil production, gathering, transportation and treatment are accompanied by scaling of radioactive materials (NORM) on technological equipment. Previously, as a rule, radiative influence at the expense of only external irradiation was estimated during servicing and repair...

... 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...
