The project activities were divided in five interrelated Work Packages (WPs). All the involved organizations had a role in each WP, but the lead of each WP was given to a different organization. The Work Packages and their leaders were:
Work Package 1: Terrestrial Environment, leader Norwegian Radiation Protection Authority (NRPA)
Work Package 2: Marine Environment, leader Murmansk Marine Biological Institute (MMBI)
Work Package 3: Atmosphere, leader Arctic Research Center of Finnish Meteorological Institute (FMI) in Sodankylä
Work Package 4: Social Impacts, leader Pöyry Finland Oy
Work Package 5: Public Awareness, leader Norwegian Radiation Protection Authority
STUK was the project leader and coordinated the activities in all work packages, and its Regional Laboratory of Northern Finland was involved especially in WP 1, collecting and analyzing environmental samples from Lapland. The laboratories of NRPA in Troms and Svanhovd participated in WP 1 by collecting and analyzing samples in their regions. The laboratory of MMBI in Murmansk collected and analyzed samples for WPs 1 and 2. Also participating in the WP activities were Norwegian Meteorological Institute (NMI) and Southern Scientific Centre of the Russian Academy of Sciences (SSC RAS).The Finnish and Norwegian partners have a long history of cooperation on various issues concerned with radiation protection and radioecology. The CEEPRA project provided ways to improve links and cooperation between the Finnish and Norwegian partners with partners from Russia. Several activities have already been initiated between Finland, Norway and Russia on regional and administrative levels, but there has been only little or no direct collaboration between authorities and research institutions dealing with environmental radioactivity. The activities included in work packages were aiming at improving cross-border cooperation and exchange of information, data, skills and knowledge. Besides, the project gave a possibility for joint researches and assessments, improved current competences, techniques and methodologies of participating laboratories, and expanded the existing risk assessment models. When the cooperation between the three nations was improved, common strategies for emergency situations and routine monitoring were developed in Finland, Norway and Russia. They also acted jointly when providing appropriate information for public, and together increased the awareness and knowledge of radiation protection issues concerning the EuroArctic region.
