GAMMA RADIATION DAMAGE AND DECONTAMINATION EVALUATION OF PROTECTIVE COATINGS AND OTHER MATERIALS FOR HOT LABORATORY AND FUEL PROCESSING FACILITIES

摘要

Protective coatings and other plastic materials were eval¬uated by irradiation in a gamma source and by decontamination tests as an extension of previous tests and for possible use in hot laboratories and fuel processing facilities and other process environs at Oak Ridge National Laboratory. Materials used may be subjected to gamma exposures of 104 to 105 r/hr and neutron exposures of 4.2 x 104 to 2.1 x 105 neutrons/cm2/sec.nEpoxy, modified phenolic and inorganic zinc protective coat¬ings were superior to the other generic types tested in radiation environments.
