The ray analysis method is applied to the problem of γ-ray streaming through multibend cylindrical ducts. In this application, the total path length of a γ-ray photon through the shielding material is determined by calculating one by one the positions of the intersections between the straight line representing the direction of photon travel and the surfaces of the shield or of the wall of the bent duct, as the photon passes from duct into wall and out of wall into duct.<BR>Based on this procedure of calculation, two computer programs have been prepared for the estimation of collision-free and total γ-ray doses as well as single and total scattered γ-ray doses behind a shield with multibend cylindrical duct.<BR>The results of calculation with these programs are compared with the experimental values obtained by Shure and Marshall, and fairly good agreement is obtained.
