Experimental qualification of a code for optimizing gamma irradiation facilities

Dose prediction and process optimization in a gamma sterilization facility using 3-D Monte Carlo code

“…This approach has the advantage of speed but relies on a direct-line attenuation model that may not include all of the 3-D scattering events in a complex geometry. However, even early applications were able to achieve agreement with dosimetry within 5-7% for homogeneous (uniform density) materials and provided useful dose rate distributions and isodose curves (Mosse et al, 1988;Raisali et al, 1990). Detailed model descriptions of actual product (Petri dishes) provided good agreement (3-8%) with dosimetry using QAD-CGGP code (Pina-Villalpando and Sloan, 1995).…”
