Commonly, γ -rays are produced by radioactive isotopes such as cobalt-60 and cesium-137. These isotopes have been approved for use in food because the γ -rays they produce have insufficient energy to induce radioactivity in foods. ... Consumer concerns about food irradiation fall into two broad categories:

The two isotopes most commonly used for food irradiation are co-60 and cs-137. ... So the short answer, is the gammas being used don't have enough energy to produce neutrons which could be absorbed to possibly make food radioactive. ... Ionizing radiation has sufficient energy to remove electrons from atoms [hence the name "ionizing"],

Radioactivity in foods can occur by two routes: ... The irradiation process involves passing food through an irradiation field; however, the food itself never contacts a radioactive substance. Also, the ionizing radiation used by irradiators is not strong enough to disintegrate the nucleus of even one atom of a food molecule.

Naturally occurring and man-made radionuclides, also called radioactive isotopes or radioisotopes, are unstable, and emit radiation as they spontaneously disintegrate, or decay, to a stable state. The radionuclide used almost always for the irradiation of food by gamma rays is cobalt-60.

The other forms of radiation are undesirable because they have the potential to make the target food (or medical product) radioactive.[19] To date, the only radioactive isotopes approved as having the proper radiation profile are Cobalt 60 and Cesium 137, with only Cobalt 60 being actually used for food irradiation at...
