Abstract
In this paper the calculation of exposure build up factors for photons of three energies (1.6, 6.13 and 7.10 MeV) has been performed applyin g two different methods namely, the Bowman & Trubey (Bowman and Trubey , ORNL-2609, 1958) and Broder (Broder et al., Sov. At. Energy 12, 26, 1962) formulae. Photon penetration for double shielding slabs of six p ossible combinations of aluminium (Al), steel (Fe) and lead (Pb) was e xamined. Transmission dose build up factors obtained in the present st udy have been compared with those reported recently (Bakos, Ann. Nucl. Energy 21, 725, 1994) using the Harima & Nishiwaki formula.
