Some examples of the MRA application in trading of radionuclide products and radioecological monitoring.

Three examples of bilateral cooperation connected with trading of radionuclide products and radioecological monitoring, are discussed. The example in the field of trading is related to the shipment of Russian sources with a high specific activity of 60Co applied for radiation therapeutics to the UK. The examples in the field of radioecological monitoring concern the establishment of equivalence between the 235U reference standards used in Russia and the USA to classify SNM monitors and ensure radiation safety at salvage of the "Kursk" nuclear-powered submarine.
