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).
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.
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.
Hay and straw were found contaminated with caesium 80 kilometres (50 mi) from the reactors and outside the evacuation zone. The news of the contamination of foods with radioactive substances leaking from the Fukushima nuclear reactors damaged the mutual trust between local food producers, including farmers, and consumers.
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 ...
Fruits, vegetables, seeds and beans are all essential parts of a well-balanced and healthy diet, but if these health gems are not consumed properly, they could be poisonous and detrimental to our ...
AGM2015: A worldwide v̄ e flux map combining geoneutrinos from natural Uranium-238 and Thorium-232 decay in the Earth's crust and mantle as well as manmade reactor-v̄ e emitted by power reactors worldwide. Environmental radioactivity is part of the overall background radiation and is produced by radioactive materials in the human environment.
He cites a 2021 congressional report that found many baby foods in the United States — including organic brands — were contaminated with lead and other heavy metals, including cadmium and ...
