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.
Adequate food has also been defined as a human right. The emphasis on access in these definitions also implies that security is not so much about average (e.g., annual) availability of resources; it has to encompass variability and extreme situations such as droughts or price shocks, and the psychological resilience of the poor.
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]
Women selling produce at a market in Lilongwe, Malawi. Food security is the state of having reliable access to a sufficient quantity of affordable, nutritious food.The availability of food for people of any class and state, gender or religion is another element of food security.
Nutritional anthropology [1] is the study of the interplay between human biology, economic systems, nutritional status and food security.If economic and environmental changes in a community affect access to food, food security, and dietary health, then this interplay between culture and biology is in turn connected to broader historical and economic trends associated with globalization.
The International Facility for Food Irradiation Technology (IFFIT) was a research and training centre at the Institute of Atomic Research in Agriculture in Wageningen, Netherlands, [1] sponsored by the Food and Agriculture Organization (FAO) of the United Nations, the International Atomic Energy Agency (IAEA) and the Dutch Ministry of Agriculture and Fisheries.
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]
Another important factor is the distance between the worker and the source of radiation. In the case of arc welding , infrared radiation decreases rapidly as a function of distance, so that farther than three feet away from where welding takes place, it does not pose an ocular hazard anymore but, ultraviolet radiation still does.
