Monte Carlo studies of the irradiator geometry of the Portuguese Gamma Irradiation Facility

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

“…However, an overall REA of 70% for the outer racks has been factored into all dose predictions for this facility with good reliability. This result is in conflict with the study by Oliveira et al (2002), where a linear relationship with source strength was predicted for several different source configurations. In this study, the REA in the outer rows was less than that of the inner rows; hence, a non-linear dose rate can develop with increasing source activity when loaded in this manner.…”
