At around 5:30 am on July 16, 1979, a previously identified crack opened into a 20-foot-breach (6.1 m) in the south cell of United Nuclear Corporation's Church Rock temporary uranium mill tailings disposal pond, and 1,100 short tons (1,000 t) of solid radioactive mill waste and about 93 million US gallons (350,000 m 3) of acidic, radioactive tailings solution flowed into Pipeline Arroyo, a ...
The Windscale fire resulted when uranium metal fuel ignited inside plutonium production piles; surrounding dairy farms were contaminated. [33] [34] The severity of the incident was covered up at the time by the UK government, as Prime Minister Harold Macmillan feared that it would harm British nuclear relations with America, and so original reports on the disaster and its health impacts were ...
Uranium mining is the process of extraction of uranium ore from the ground. ... Of the 150,000 laborers, 1281 were killed in accidents and 20,000 suffered injuries ...
In a smaller scale accident at Sarov a technician working with highly enriched uranium was irradiated while preparing an experiment involving a sphere of fissile material. The Sarov accident is interesting because the system remained critical for many days before it could be stopped, though safely located in a shielded experimental hall. [121]

Along with studies regarding the correlation between uranium miners and lung cancer there have been other studies that suggest that miscarriages, birth defects, reproductive, bone and gastric cancer along with heart disease deaths have also been identified as related health effects of uranium mining (Churchill 1986, Gofman 1981, McLeod 1985).

One of four example estimates of the plutonium (Pu-239) plume from the 1957 fire at the Rocky Flats nuclear weapons plant. The Rocky Flats Plant, a former United States nuclear weapons production facility located about 15 miles (24 km) northwest of Denver, caused radioactive (primarily plutonium, americium, and uranium) contamination within and outside its boundaries.
