Detailed explanation-1: -During irradiation, gamma rays, x-rays, or high-energy electrons pass through the food, destroying or inactivating bacteria and viruses that cause foodborne illness.
Detailed explanation-2: -Ionizing Radiation. Radiation for the treatment of food is achieved through the application of gamma rays (with Co-60 or Cesium-137 radioisotope), electron beams (high energy of up to 10 MeV), or X-rays (high energy of up to 5 MeV).
Detailed explanation-3: -Gamma irradiaton of food. Food irradiation is the process of exposing boxes or pallets of food products to radiation from a Cobalt-60 source. The ionizing radiation destroys dangerous contaminates in foods such as bacteria, viruses, fungi and insects. The process is not new; it’s been around for the past 60 years.
