The paper describes a Monte Carlo study for planning the irradiation of test samples for
microbiological validation of distinct products in the Portuguese Gamma Irradiation Facility.
Three different irradiation geometries have been used. Simulated and experimental results
are compared and good agreement is observed. It is shown that Monte Carlo simulation
improves process understanding, predicts absorbed dose distributions and calculates dose
uniformity in different products. Based on these results, irradiation planning of the product …
