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).
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).
Similar to the Catholic church – which has preserved and authorized its message for almost 2,000 years – the atomic priesthood would have to preserve the knowledge about locations and dangers of radioactive waste by creating rituals and myths. The priesthood would indicate off-limits areas and the consequences of disobedience.
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 ...
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 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 ...
Most of the radioactive contamination from Rocky Flats came from three sources: a catastrophic fire in 1957, [19] leaking barrels in an outdoor storage area in 1964–1968, and another, less severe fire in 1969. [20] Plutonium, used to construct the weapons' fissile components, can spontaneously combust at room temperature in air.
Radioactive waste is a type of hazardous waste that contains radioactive material.It is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, nuclear decommissioning, rare-earth mining, and nuclear weapons reprocessing. [1]
