Abstract

Abstract Samples of lanthanum, tantalum and erbium which are constituents of structural materials and insulating coatings for blankets of fusion reactor designs have been irradiated in a fusion peak neutron field. The induced gamma activities were measured and the results were used to validate calculations with the European activation system EASY-2005. Good agreement for the prediction of major contributors to the contact dose rate of the materials was found, but for minor contributors the calculation deviated up to 50%.
