  1. How it works. Food irradiation works by exposing food to ionizing electromagnetic (gamma or x-ray) radiation. Food irradiation is considered a "cold" method, meaning it does not use heat to kill germs. Other food safety processes that you may be more familiar with, like pasteurization and canning, use heat.

    Radiation is both natural and man-made. Our bodies are exposed to natural radiation every day -- from soil and underground gases to cosmic radiation from the sun and outer space. We're also exposed to radiation from our own inventions -- medical procedures, televisions, cell phones and microwave ovens. Radiation isn't necessarily always dangerous. ...

    Most people will tell you Marie Curie discovered radiation, along with her husband and research partner Pierre. And that's right -- sort of. Curie actually discovered the element radium in 1898, an accomplishment that would make her the first female recipient of the Nobel Prize. However, three years earlier in 1895, a scientist named Wilhelm Röntge...

    Radiation is energy that travels in the form of waves (electromagnetic radiation) or high-speed particles (particulate radiation). Particulate radiation happens when an unstable (or radioactive) atom disintegrates. Electromagnetic (EM) radiation, on the other hand, has no mass and travels in waves. EM radiation can range from very low energy to ver...

  2. Jun 28, 2017 · Irradiation pasteurizes food by using energy, just as milk is pasteurized using heat. At the level used, most harmful bacteria will be destroyed. Afterwards, surviving bacteria could start to multiply if the food were mishandled: such as, stored at an improper temperature. The level of irradiation used also does not kill certain spoilage ...

    Food irradiation is the treatment of food with a type of radiation energy known as ionizing radiation. Ionizing radiation may be used for various reasons depending on the food: it may be used to kill microorganisms that can cause human illness or cause food to spoil; to control insect or parasite infestation; or to slow the ripening or ...

  4. Food irradiation is the treatment of food with a type of radiation energy known as ionizing radiation. Three different types of ionizing radiation can be used on foods sold in Canada; gamma rays, electron beam and x-rays. Ionizing radiation at the levels used for food irradiation contains enough energy to kill bacteria, molds, parasites and ...

    Irradiation. Irradiation is the process by which an object is exposed to radiation. An irradiator is a device used to expose an object to radiation, notably gamma radiation, for a variety of purposes. [1] Irradiators may be used for sterilizing medical and pharmaceutical supplies, preserving foodstuffs, alteration of gemstone colors, studying ...

  7. During the irradiation process, food is exposed to an ionizing energy source. Three different energy sources may be used: gamma rays, electron beams and x-rays. The length of time the food is exposed to the source and the energy level determine the dose of irradiation. The doses used for food irradiation do not result in the food becoming ...
