Explanation:
Detailed explanation-1: -The food is exposed to ionising radiation, either from gamma rays or a high-energy electron beam or powerful x-rays.
Detailed explanation-2: -Food irradiation works by exposing food products to ionizing radiation. Food irradiation is considered a “cold” method, meaning it does not use heat to kill germs.
Detailed explanation-3: -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.
