Irradiation of Foodby Shea Conboy and Anesa
In America, the FDA regulates the irradiation throughout the country. The irradiation of food is beneficial to our health and general society as it prevents food borne illness, helps preserve the food longer, destroys harmful insects, delays ripening of food so it can last longer, and sterilizes food.

This is the symbol of food irradiation in America.
While the food undergoing irradiation is acutely exposed to radiation, food that has been irradiated is safe to eat. However, some people are concerned that irradiating food may lose vitamins and nutrients during storage. Some commonly irradiated foods are spices, fruits, meats, fruit/vegetable juices, poultry and vegetables. The first food approved for irradiated was bacon in 1963.

To irradiate food, they use gamma rays, X-rays, and electron beams to kill bacteria and extend shelf life.
There are three types of radiation approved for the use of food: gamma rays, X-rays, and electron beams.
Gamma rays are emitted from the radioactive forms of Cobalt 60 and Cesium 137. Gamma Rays are used to sterilize medical and household equipment and is used for the treatment of cancer but it is not typically used for the irradiation of food even though it is approved to do so.
X-Rays are produced by reflecting a high-energy stream of electrons off a target substance into food. X-Rays are also used in the medical field.
Electron Beams are a stream of high-energy electrons propelled from an electron accelerator into food. Electron Beams are also called e-beams.
