Detailed explanation-1: -Food irradiation does not make food radioactive. Food irradiation reduces or removes pathogens, such as bacteria and molds, that spoil food and cause food poisoning and other illness. For example, irradiation can kill Escherichia coli, Campylobacter and Salmonella bacteria.
Detailed explanation-2: -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). Radiation principles explain how the gamma rays, e-beams and X-rays interact with matter.
Detailed explanation-3: -Currently, food irradiation is approved for use in over 55 countries worldwide. Some 20 countries, including Argentina, Australia, Bangladesh, Thailand, the USA and Vietnam have legislation allowing phytosanitary uses of irradiation.
