    the American food processing system. Previously, only cobalt irradiators had been used for food irradiation. • When electron beam or X-ray machines are used, no radioactive isotopes are involved. When a cobalt source is used, food irradi - ation facilities and transport of radioactive source must meet strin - gent federal and state. THE EFFECTS OF ELECTRON BEAM IRRADIATION ON ADDITIVES PRESENT IN FOOD-CONTACT POLYMERS A CRQWSQN A range of additives (Irganox , Irganox , Irganox , Irgafos and Tinuvin ) has been incorporated into a variety of food-contact polymers including polypropylene and low density polyethylene. Samples of.

    Efficacy of Electron Beam Irradiation of Processed Pork Products Fredy A. Cardona, Patrick D.

Analysis of organic acids in electron beam irradiated chestnuts emitted by the radioactive elements cobalt (60Co) or cesium (Cs) with high penetrating power, high-energy electron beams with limited penetration depth generated from electron accelerators operated at or below an energy level of 10 MeV and x-rays generated from.

    Yes. This is why irradiation with cobalt is no longer approved by the FDA. Yes. However, the radioactivity resulting is well below the danger level established by the FDA. No. The gamma rays do not have sufficient energy to initiate a nuclear reaction in the atoms of the food. Yes and No. back. Radioactive 60 Co can be generated by irradiating the stable element 59 Co with neutrons inside a reactor. 60 Co decays to 60 Ni with a half-life of T ½ = d. The decay of a 60 Co nucleus releases one electron with keV energy and two gamma quanta with energies of MeV and MeV.

Food irradiation is the process of exposing food and food packaging to ionizing ng radiation, such as from gamma rays, x-rays, or electron beams, is energy that can be transmitted without direct contact to the source of the energy capable of freeing electrons from their atomic bonds in the targeted radiation can be emitted by a radioactive substance or generated.

Food irradiation kills pathogens and parasites to extend shelf life. Along with accelerators, Cobalt gamma sources are widespread in food irradiation and medical sterilization. Food irradiation technologies exploit the part of the electromagnetic spectrum that encompasses wavelengths shorter than 10 –10 m.

Radiation from this region of the electromagnetic spectrum is called ionizing radiation, because it can ionize materials and molecules that it encounters ().Gamma radiation, X-ray, and eBeam radiation are examples of ionizing radiation.

The Federal Government began allowing food manufacturers to irradiate raw meat and meat products to control pathogenic microorganisms in February Consumer acceptance of irradiated foods could affect public health because many foodborne illnesses occur when consumers handle or eat meat or poultry contaminated by microbial pathogens.

investigated: Cobalt 60 (a radionuclide source), X-rays, and an electron beam source. The e-beam source was selected, due to the limiting weight of the necessary shielding for the other two sources. Strawberries were selected as the food product to be irradiated.

An electron beam source was chosen that would provide the appropriate dose. Electron accelerators are a good source of bremsstrahlung currently employed in food irradiation for the preservation and extension of the shelf-life of food (Miller, Mehta et al,Auslender et al,Farkas, L'Annunziata,and Farkas et al, ).

food businesses as part of their normal processes, but efforts to turn food irradiation into an "in-house" technology have been limited.

Due to their limited penetration, electron accelerators appear most appropriate for the irradiation of individual units of food products (rather than larger packaging units) andFile Size: KB. Development of Electron Beam and X Ray Applications for Food Irradiation Summary: The majority of food and agricultural products treated by irradiation are processed in facilities using gamma radiation from cobalt as the source of ionizing radiation.

Gamma irradiation is a .Cobalt irradiation facility is used to test irradiation as a tool to ensure food safety.
