In 2004 Murmansk region administration and the northernmost county in Norway Finnmark signed a contract stipulating decommissioning and shipment of 10 RTGs, Interfax reported. Norway allocated about $416 thousand for this project. It expected that all 10 RTGs will be placed at the Mayak plant by December 2005. Besides, Norway allocated $1.3m to install solar panels on 31 lighthouses. The plans for 2005 stipulate three projects involving decommissioning of 31 RTGs and installation of solar panels on 30 lighthouses. The total cost of the projects is $3m. Norwegian government plans to change all the RTGs with solar panels. The price of one solar panel is $35 thousand. The projects will be financed in the frames of the Multilateral Nuclear Environment Program for Russia, MNEPR.
RTGs are used from the end of 60s for supplying energy for the navigation beacons and seamarks in the inaccessible seaside regions. The generator transforms the heat energy of strontium-90 into the electricity for the lighthouse. The 90Sr isotope’s radioactive half-life is 29.1 years. At the time of their production, RHS-90 contains from 30 to 180 kilocuries of 90Sr. The level of gamma radiation reaches 400 to 800 roentgen per hour, or R/h, at a distance of 0.5 metres, and 100 to 200 R/h at a distance of one metre from the RHS-90. It takes no less than 900 to 1000 years before RHSs reach a safe radioactivity level.
153 RTGs are scattered along the shorelines of the Barents and White Seas, of which 17 are located in the Kandalaksha Gulf. 55 RTGs have been shipped for final disposal from Murmansk and Arkhangelsk region (36 from Murmansk region, 19 from Arkhangelsk region) thanks to the contract with Norwegian Finnmark county. At present 52 RTGs remain in Murmansk region, and 46 in Arkhangelsk region what includes Novaya Zemlya, Interfax reported.

A survey of events in the field of nuclear and radiation safety relating to Russia and Ukraine.
A visit last week by Vladimir Putin and a Kremlin entourage to Astana, Kazakhstan sought in part to put Rosatom, Russia’s state nuclear corporation, on good footing with local officials.
Russia is formally withdrawing from a landmark environmental agreement that channeled billions in international funding to secure the Soviet nuclear legacy, leaving undone some of the most radioactively dangerous projects and burning one more bridge of potential cooperation with the West.
