Dose calculation using Haar wavelets with buildup correction

In this work, we focus on the buildup correction of dose calculation using Haar wavelets in the Tunisian gamma irradiation facility. The buildup effect of gamma rays was used to adjust absorbed dose calculation for different depth in the irradiated products. A buildup study with different product densities was carried out to generalize the dose adjustment approach to any product at any depth. - Highlights: • A buildup correction method of calculated dose using Haar wavelets is presented. • Corrected absorbed dose is calculated for lPropane and water. • Buildup factor fit as function of product density is performed. • Buildup factor fit is applied to diethyl ether and polypropylene.
