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 sediment of the lake bed is estimated to be composed almost entirely of high level radioactive waste deposits to a depth of roughly 11 feet (3.4 m). In 1994, a report revealed that 5 million cubic meters of polluted water had migrated from Lake Karachay, and was spreading to the south and north at 80 meters per year, "threatening to enter ...
Lake Karachay (Russian: Карача́й), sometimes spelled Karachai or Karachaj, was a small lake in the southern Ural Mountains in central Russia.Starting in 1951, the Soviet Union used Karachay as a dumping site for radioactive waste from Mayak, the nearby nuclear waste storage and reprocessing facility, located near the town of Ozyorsk (then called Chelyabinsk-40).
The radiation is believed to be aircraft instruments discarded in World War Two [Getty Images] ... There have been concerns about radioactive pollution at other Scottish sites in the past.
The images show what various parts of the country looked like before the air and water protections that exist today.
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 reports say for years Chelyabinsk dumped about 120 million curies of radioactive waste to give you an idea of how much that is -- it's two and a half times the amount of radiation released in ...
Radium, like radon, is radioactive and is found in small quantities in nature and is hazardous to life if radiation exceeds 20-50 mSv/year. Radium is a decay product of uranium and thorium. [2] Radium may also be released into the environment by human activity: for example, in improperly discarded products painted with radioluminescent paint.
