What is the difference between radiation and irradiation?

Sun light is radiated.

We do not say we are irradiated with sun light.

Radiation takes place in Nuclear plant.

We are irradiated if we are exposed to the unprotected nuclear plant zone.

    I found a lot on the topics.

    1. Gamma Radiation:

    A form of pure energy that is generally characterized by its deep penetration and low dose rate, gamma is currently the most widely used and proven form of food irradiation.

    Similar to X-ray, the gamma process utilizes photons. In gamma, photons are generated from Cobalt-60 to completely penetrate materials such as:

    bulk spices

    botanical ingredients


    food packaging

    cosmetic powders and applications

    2. Food Irradiation

    Food irradiation is a technology for controlling spoilage and eliminating food-borne pathogens, such as salmonella. The result is similar to conventional pasteurization and is often called "cold pasteurization" or "irradiation pasteurization." Like pasteurization, irradiation kills bacteria and other pathogens, that could otherwise result in spoilage or food poisoning. The fundamental difference between the two methods is the source of the energy they rely on to destroy the microbes. While conventional pasteurization relies on heat, irradiation relies on the energy of ionizing radiation. The FDA emphasizes that no preservation method is a substitute for safe food handling procedures.

    How is food irradiated?

    Bulk or packaged food passes through a radiation chamber on a conveyor belt. The food does not come into contact with radioactive materials, but instead passes through a radiation beam, like a large flashlight. The type of food and the specific purpose of the irradiation determine the amount of radiation, or dose, necessary to process a particular product. The speed of the belt helps control the radiation dose delivered to the food by controlling the exposure time. The actual dose is measured by dosimeters within the food containers.

    Cobalt-60 is the most commonly used radionuclide for food irradiation. However, there are also large cesium-137 irradiators and the Army has also used spent fuel rods for irradiation.

    What are the sources of radiation used?

    The food irradiation process uses three types of ionizing radiation sources:

    cobalt-60 gamma sources

    electron beam generators

    x-ray generators

    3. radiation causes bad effects on human bodies, and that those effects are far greater than anyone has ever allowed us to believe.

    Radiation exposure will cause a person to have a weakened immune system and related health problems throughout his entire life. This exposure causes devastating illnesses, such as cancer and degenerative diseases, but it can also cause minor ailments, such as a persistent cough, headaches, sleep disturbances and gastrointestinal dysfunction.

    Food irradiation is a process whereby the food is exposed to high levels of radiation in order to kill insects, bacteria and mold, and make the food last longer on the store shelves. Although the idea of radiating food sounds quite unappetizing to most people, it has been practiced in the USA since the 1960's, when the Food & Drug Administration approved the irradiation of wheat and white potatoes. During the 1980s, the FDA approved petitions for irradiation of spices and seasonings, pork, fresh fruits, and dry or dehydrated substances. Poultry received approval in 1990. The FDA approved irradiation for red meat in 1997.

    The type of radiation used to irradiate foods is gamma energy, because gamma rays do not create radioactive particles. "Meltdown" and chain reactions do not occur, and the irradiated foods and their packaging are apparently not made radioactive. The gamma energy penetrates the food and its packaging, but most of the energy simply passes through the food, similar to the way microwaves pass through food, leaving no residue. The small amount of energy that does not pass through the food is negligible and is retained as heat.

    You've already answered your question mostly, but I'll add:

    To radiate is to give off energy. Sun radiates because it gives off it's light and heat.

    To irradiate is to expose something or someone to radiant energy, usually nuclear radiation. Food irradiation is one example, in which spices or fruits are exposed to high levels of gamma rays to kill all living bacteria and make the food less susceptible to rotting. The food doesn't become radioactive itself, it's just like it's been given 80,000 chest x-rays at once.

    I've been told that an irradiated fruit can sit on a shelf for months without going bad. I wouldn't want to eat fruit like that.

    To summarize, a radioactive source RADIATES, while something in it's path gets IRRADIATED.

    Radiation generally means the transmission of waves, objects or information from a source into a surrounding medium or destination.

    Irradiation is the condition of being exposed to radiation

  • 1 decade ago

    There are two types of radiation, electromagnetic and particle. Electromagnetic radations are gama rays, x-rays, light waves, micro waves and radio waves. Particle radation results from some atomic process and consistes of various bits and pieces

    of matter, usually moving at high speeds.

    When something is exposed to either form of radiation it is said to have been irradiated or to be being irradiated.

    It would not be wrong to say we are irradiated by sun light, its just not common usage.
