Abstract : Exposure rates from radioactive fallout associated with concrete and wood debris were calculated using the SAM-A three-dimensional adjoint gamma ray Monte Carlo computer code. The geometric model was a cylinder of varying radius and altitude. Homogeneous masses of both materials were considered for the cases of fallout on top of under, and uniformly mixed with the debris. Next, three inhomogeneous configurations of debris were considered. The resulting exposure rates were compared with those obtained using the homogeneous model. Finally, the exposure rates near the shoreline of a semi-infinite body of water, under which fallout was uniformly distributed, were determined. (Author)
