Abstract
Ensuring safe and easy operation providing relative uniform dose in the product and maximizing radiation utilization are the basic design principles for each Co60 industrial irradiator to maintain radiation safety. The study shows an assessment for four industrial irradiators to determine which active results were been maintained by using basic design principles. Different designs elements of the chosen irradiators have been illustrated and studied. The study shows that IRASM and ROBO industrial irradiators satisfy all basic design principles. IAEA-NR3772 irradiator maintains only two of the three basic design principles due to rotating door. Brevion irradiator satisfies only the principle of relative uniform radiation dose in product. Without affecting radiation safety this study proposes a new design of the irradiator to maximize energy utilization by adding a new track for low density products and also a static irradiation for cultural heritage beside the main track of high density products.
