Abstract : The penetration of gamma rays into compartments of an aircraft carrier from three different radioisotopes was measured. Co60, Cs137 and Ir192 sources were exposed on the Flight Deck and dosimeters were used to measure dose in two general areas of the ship at three different deck levels. Data of dose distribution are presented for the three sources used and for the different source points considered. Diagrams indicating source positions, detector positions, deck and compartment wall thicknesses and main structural member specifications are also presented. (Author)
