Computational methods in nuclear radiation shielding and dosimetry: AMBIENT DOSE BUILDUP FACTORS

Abstract

Accurate dose measurement and shielding calculation are two aspects of quality assurance procedure in all applications of ionising/nuclear radiations. The consideration of the radiation dose buildup factor is very critical in the dose measurement and shielding requirement calculations. The determination of the buildup factor is an important topic in radiation applications. This chapter highlights the concept of photons and neutron dose buildup factors as it affects radiation dosimetry and shielding. The meaning, application, and different ways of measuring and calculating buildup factors have also been discussed. The merits and demerits of each of the methods have been discussed, and the general behaviour of the photon buildup factor regarding energy and depth have been fully highlighted.
