[Radio-ecological situation in the area of JSC "Priargunsky Production Mining and Chemical Association"].

In order to assess the radioecological situation created in the area of the location of diversified uranium mining enterprise "Priargunsky Production Mining and Chemical Association" (PIMCU) there was investigated the radioactivity of a number of the compartments of environment, both at the industrial site and beyond it, as well as the volume activity of radon inside the ground and working premises. Radioecological situation in the vicinity of the uranium mines was performed in comparison with the background (fixed reference, control) district, where there is no uranium mining. Performed studies have shown the significant excess content of 226Ra, 232Th, 210Pb, 222Rn in soil, water open water bodies and local foods near uranium mines compared to areas outside the zone of influence of uranium mining that allows to make a conclusion about the significant technogenic pollution of local areas of the plant and adjoining territory.

[Regulatory supervision and radiation survey in the area of location of former military technical bases].

Activities related to the rehabilitation of areas and facilities of the temporary storage of spent nuclear fuel and radioactive waste (SNF and RW) at Andreeva Bay and Gremikha on the Kola Peninsula and in the Primorsky Krai in the Russian Far East is an important component of the regulatory functions of the Federal Medical biological Agency (FMBA of Russia). Technical support to the FMBA of Russia in this activity is provided by A.L Burnazyan Federal Medical Biophysical Center Main research interests include evaluation of radiological threats to determine the priority directions of regulation, a detailed analysis of the radiation situation at areas, territories and in vicinity of temporary waste storage facilities, radiation control and environmental monitoring, the development of digital maps and geoinformation systems, project expertise in the field of rehabilitation of PVC including the management of SNF and RW Implementation of these natural, practical and theoretical works is completed by development a set of regulatory documents ensuring adherence to radiation safety for the stuff population and the environment, and the also documents governing the management of SNF and RW waste in the territories of PVC.

Regulatory supervision of sites for spent fuel and radioactive waste storage in the Russian northwest.

In the 1960s two technical bases for the Northern Fleet were created in the Russian northwest at Andreeva Bay in the Kola Peninsula and Gremikha village on the coast of the Barents Sea. They maintained nuclear submarines, receiving and storing radioactive waste and spent nuclear fuel. No further waste was received after 1985, and the technical bases have since been re-categorised as temporary storage sites. The handling of these materials to put them into a safe condition is especially hazardous because of their degraded state. This paper describes regulatory activities which have been carried out to support the supervision of radiological protection during recovery of waste and spent fuel, and to support regulatory decisions on overall site remediation. The work described includes: an assessment of the radiation situation on-site; the development of necessary additional regulatory rules and standards for radiation protection assurance for workers and the public during remediation; and the completion of an initial threat assessment to identify regulatory priorities. Detailed consideration of measures for the control of radiation exposure of workers and radiation exposure of the public during and after operations and emergency preparedness and response are complete and provided in sister papers. The continuing requirements for regulatory activities relevant to the development and implementation of on-going and future remediation activities are also outlined. The Norwegian Radiation Protection Authority supports the work, as part of the Norwegian Government's plan of action to promote improvements in radiation protection and nuclear safety in northwest Russia.
