Enhancement of Radiation Safety in Industrial Cobalt -60 Irradiator During Abnormal Conditions

Enhancement of radiation safety in industrial cobalt -60 irradiator unit is a necessity need to protect working staff and the environment against radiation release by applying radiation safety standards inside and outside industrial during normal and abnormal operating conditions. This could be fulfilled by preventing stacking, falling, and probability broken cobalt-60 radiation capsules which could lead to water contamination inside the storage pool. The water of storage pool is contaminated by broken hot capsule where the radiation source is changed from close radiation source to very dangerous open radiation source. This paper presents a proposed modified design with concrete shielding maze having more than one right – angle bend to maintain radiation prohibitive and to determine the smallest radiation exposure rates at the entrance of maze design with several legs.
