Many of Industrial radiation facilities using Co-60 irradiation are used in many countries in
development for sterilization of medical products and pharmaceuticals, with a small numbers being
used for processing of food items. The total instated capacity for processing of medical products at 20-
25 K Gy is about one million tones annually.
The designing analysis of different irradiation units which have the radiation activity and IV category
cleared that the radiation safety and good function of design elements were maintained of them.
The Russian radiation design is the best one of its category IV because it has the longest interior
dimensions and many active elements over others.
There is a need to make some modifications on the design of these radiation canyons to allow
radiation research, during mass production. By designing a new track for experimental research which
can pass inside and outside radiation canyon through a special maze (labyrinth). The research samples
will be put in two boxes out side the research door and they will go inside the canyon through research
maze and stopped behind the products cars on two position, facing the source rack which will be in
radiation position. The boxes will return back after finishing the exposure period.
