How Does a Food Irradiator Work?


Here’s a description of what you’ll see in this animation. Products are loaded into totes for irradiation. These products can be medical devices, consumer products or food products such as spices, meats, fruits or vegetables. The totes enter the shielded irradiation room through a maze in the concrete, then the totes are indexed around a source of radiation. The radiation from the source penetrates through the totes to deliver the required amount of energy to the entire product. The shielded concrete walls absorb any remaining energy. The product never comes into contact with the source, and the energy from the source cannot make the products radioactive. Once the totes have traveled the full distance around the source and out the exit maze, the products can be safely unloaded and are ready to be shipped to the end user.
