The primary objective of the workshop is to examine how scientific research and environmental studies, including the effects and distribution of radiation and radio-nuclides, can contribute to development of practical standards for protection of the environment and human health. The output is intended to be useful to operators and regulators involved in radioactive waste management projects in Northwest Russia, who are also responsible for Environmental Impact Assessment and regulatory aspects of risk estimation. Secondary objectives include the exchange of information on the application of risk assessment methods as applied to these projects and the regulatory process applied to these projects.

At work in territory of coastal technical bases (CTB) in an environment act radio nuclides, contained on technical objects and in objects of an environment in CTB territory. During works they are essentially redistributed, pollute the process equipment, surfaces of working rooms, CTB territory and objects of an environment, concentrating in some cases up to significant levels, at which probably increased irradiation of the personnel and population and secondary pollution of objects of an environment.

In planning and realization of various nuclear projects it is often necessary to make an evaluation of radiation impact levels and assess the values of the associated risks due to possible radiation contamination of the marine environment.

There is a significant number of past, present or potential nuclear sources, which have contributed, are still contributing, or have the potential to contribute to radioactive contamination of the environment. To protect the environment from past, present and future contamination, impact and risk assessments should be performed in contaminated areas, prior to and after the implementation of any countermeasure. The ecological risk characterisation represents the integration of hazard identification, doseresponse assessment and exposure assessment. Hazard identification can be described as a qualitative description of radionuclides having potential negative effects on biota; and raise questions as which nuclides are present and which are the negative effects that these agents can cause.

Ensuring of safety and reducing of ecological hazard during dismantlement of nuclear-powered submarines present one of the most urgent issues. In the course of repairing and dismantling a large number of demountable equipment built in nuclear-powered plants that have been operated for a long time under the conditions of elevated temperatures, corrosive impact of working medium, high density of neutron flux, and being contaminated, is produced. The above equipment is manufactured, mainly, of expensive high-alloy stainless steels, titanium and copper alloys, and other valuable materials.

The chairs of the previous sessions each provided a brief summary of the main conclusions from their sessions. Sneve (NRPA) and Pechkurov (FSETAS) also made brief introductory remarks, highlighting major issues from the Norwegian and Russian perspectives respectively.
