Abstract

This study investigates the photoneutron field found in medical accelerator rooms with primary barriers constructed of metal slabs plus concrete. An increased neutron dose equivalent was observed for barriers containing lead or steel as compared to barriers fabricated entirely of concrete. The effect of the beam's size and distance from the primary barriers on the neutron dose was evaluated and the portion of the neutron dose due to the metal slabs was determined.
