Food Irradiation Food treatment comparable to pasteurization Kills pests/microorganisms without food degradation Controls sprouting Does not make the food radioactive FDA Approved Must be labeled
Nuclear Engineering Department xoubi
Food Irradiation Food irradiation is a process in which ionizing radiation is used to keep food fresh longer and kill germs. Some people have called food irradiation a method of cold pasteurization because the radiation destroys the disease-producing microorganisms with radiation energy instead of heat energy Nuclear Engineering Department xoubi
Types of Food That are Being Irradiated Meat, poultry, fish, shellfish, some vegetables, baked goods, prepared foods Spices and other seasonings Strawberries and some other fruits Grain, fruit, vegetables, and other foods subject to insect infestation Bananas, avocados, mangos, papayas, guavas and certain other non-citrus fruits Potatoes, onions, garlic, ginger Grain, dehydrated vegetables, other foods Nuclear Engineering Department xoubi
Food Worldwide Application

Gamma - Radiography This process uses gammaray radioisotopes to test materials for flaws such as invisible cracks, defects and occlusions in welds More penetrating Portable and easy to use Nuclear Engineering Department xoubi
Neutron Activation Neutron Activation is a method of determining the concentration of elements in a wide variety of samples, accurately and precisely
