How radioactive is du
NettetRadioactive 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). [3] NettetDepleted uranium, or DU, is a processed form of uranium. Uranium is a weakly radioactive heavy metal that occurs naturally in the environment. Rocks, soil, surface, water, air, plants, and animals all contain varying amounts of uranium. Because it is found everywhere on earth, we eat, drink and breathe a small amount every day.
