Radioactive contamination, also called radiological pollution, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition).
An "incident" of chemical food contamination may be defined as an episodic occurrence of adverse health effects in humans (or animals that might be consumed by humans) following high exposure to particular chemicals, or instances where episodically high concentrations of chemical hazards were detected in the food chain and traced back to a particular event.
The additional radioactivity in the biosphere caused by human activity due to the releases of man-made radioactivity and of Naturally Occurring Radioactive Materials (NORM) can be divided into several classes. Normal licensed releases which occur during the regular operation of a plant or process handling man-made radioactive materials.
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.
Radioactive contamination was found on empty land close to a residential building, with estimated dose exposure about 148 mSv/h. [93] Depleted uranium and an empty cylinder was also found in two houses in the same neighborhood. The owner was known to be a retired BATAN (National Nuclear Energy Agency of Indonesia) employee.

It is the largest reported salmonellosis outbreak in the United States since 1985. During a House subcommittee hearing into food supply safety and the recent salmonella contamination, a top federal official told panel members that agencies have found the source of the contamination after it showed up in yet another batch of Mexican-grown peppers.
Radioactive contamination is a potential danger for living organisms and results in external hazards, concerning radiation sources outside the body, and internal dangers, as a result of the incorporation of radionuclides inside the body (often by inhalation of particles or ingestion of contaminated food). [14] In humans, single doses from 0.25 ...
