| Abstract

The purpose of this research is to perform a radiological assessment for the hypothetical detonation of a radiological dispersal device (RDD) in a large populated site within Saudi Arabia. The radiological assessment includes calculation of radiation doses associated with the dispersal and deposition of radioactive material released from the RDD, as well as a proposed plan of action to help guide decision-making in response to this event. Hypothetical detonation scenarios were simulated using the HotSpot code for each of three selected radionuclides: Am-241, Cs-137, and Co-60. Different weights of explosive material from 25 to 500 pounds were used for each detonation scenario, resulting in eleven scenarios for each radionuclide. The material at risk for each detonation scenario was 50 Ci. For the Am-241 RDD the areas recommended for evacuation extended from the detonation site to 0.44 km (corresponding to a minimum total effective dose equivalent (TEDE) of 5 rem), from 0.44 km to 1.25 km (corresponding to TEDE values between 5 and 1 rem), and from 1.25 to 1.82 km (corresponding to TEDE values between 1 and 0.5 rem). Similarly, for the Cs-137 RDD the areas for evacuation extended from the detonation site to 0.013 km (corresponding to TEDE values between 1 and 0.5 rem). For the Co-60 RDD the TEDE did not exceed the protective action guide, and therefore shelter in-place is recommended for nearby residents. Areas were identified for relocation and re-settlement based on TEDE values during the first year and subsequent years following the RDD detonation. For the Am-241 RDD the area for relocation extended from the detonation site to 1.4 km (corresponding to a minimum TEDE of 2 rem). Similarly, for the Cs-137 RDD the area for relocation extended from the detonation site to 0.2 km, and for the Co-60 RDD the area for relocation extended from the detonation site to 0.053 km
