The international Radura logo, used to show a food has been treated with ionizing radiation. A portable, trailer-mounted food irradiation machine, c. 1968 Food irradiation (sometimes American English: radurization; British English: radurisation) is the process of exposing food and food packaging to ionizing radiation, such as from gamma rays, x-rays, or electron beams.
Phytosanitary irradiation is a treatment that uses ionizing radiation on commodities, such as fruits and vegetables to inactivate pests, such as insects. [1] This method is used for international food trade as a means to prevent spread of non-native organisms. [1]
The U.S. Department of Agriculture's (USDA) Food Safety and Inspection Service (FSIS) recognizes irradiation as an important technology to protect consumers. Fresh meat and poultry including whole or cut up birds, skinless poultry, pork chops, roasts, stew meat, liver, hamburgers, ground meat, and ground poultry are approved for irradiation. [18]
The city of Berkeley, California, through its nuclear-free zone law, requires that food intended for human consumption be labeled "Treated with Ionizing Radiation". Food irradiating facilities are also banned as part of this law. [11] Such requirements are seen by consumer groups as helpful information to consumers concerned about food irradiation.
Food technology is a branch of food science that addresses the production, preservation, quality control and research and development of food products. It may also be understood as the science of ensuring that a society is food secure and has access to safe food that meets quality standards.
The sources of radioactive pollution can be classified into two groups: natural and man-made. Following an atmospheric nuclear weapon discharge or a nuclear reactor containment breach, the air, soil, people, plants, and animals in the vicinity will become contaminated by nuclear fuel and fission products .
Radappertization is a form of food irradiation which applies a dose of ionizing radiation sufficient to reduce the number and activity of viable microorganisms to such an extent that very few, if any, are detectable in the treated food by any recognized method (viruses being excepted).
Irradiation of food [22] is the exposure of food to ionizing radiation. Multiple types of ionizing radiation can be used, including beta particles (high-energy electrons) and gamma rays (emitted from radioactive sources such as cobalt-60 or cesium-137). Irradiation can kill bacteria, molds, and insect pests, reduce the ripening and spoiling of ...
