Abstract : A Monte Carlo code, GADJET, is developed for the numerical integration of the adjoint transport equation for gamma radiation. The code is designed to calculate the effectiveness of structures (of arbitrary complexity) in shielding against fallout fields (finite or infinite) and to calculate the relative importance of each fallout region in contributing to the exposure rate in the structure. The mathematical formulation of the code is presented and the code is described in sufficient detail to be equivalent to a user's manual. GADJET is written in FORTRAN and has been used in solving civil defense problems. (Author)
