10 Maiores acidentes nucleares e radiação pelo número de mortos

10 Major nuclear accidents and radiation by death toll
There have been more than 20 nuclear and radiation accidents involving fatalities. These involved nuclear power plant accidents, nuclear submarine accidents, radiotherapy accidents, and other mishaps.

1. Chernobyl disaster - Ukraine (ex-URSS)

4,000 fatalities
Chernobyl disaster, Ukraine, April 26, 1986. 56 direct deaths (47 accident workers, and nine children with thyroid cancer), and it is estimated that there were 4,000 extra cancer deaths among the approximately 600,000 most highly exposed people.Estimates of the total number of deaths potentially resulting from the Chernobyl disaster vary enormously: Thirty one deaths are directly attributed to the accident, all among the reactor staff and emergency workers. A UNSCEAR report places the total confirmed deaths from radiation at 64 as of 2008. The World Health Organization (WHO) suggests it could reach 4,000 civilian deaths, a figure which does not include military clean-up worker casualties. A 2006 report predicted 30,000 to 60,000 cancer deaths as a result of Chernobyl fallout. A Greenpeace report puts this figure at 200,000 or more. A Russian publication, Chernobyl, concludes that 985,000 premature cancer deaths occurred worldwide between 1986 and 2004 as a result of radioactive contamination from Chernobyl.

2. Fukushima disaster - Japan

Frank N. von Hippel, a U.S. scientist, has suggested, as "a very preliminary order-of-magnitude guesstimate," that "one might expect around 1,000 extra cancer deaths related to the Fukushima Daiichi accident."
As of June 2012, the exact chain of events which included the explosions at the Fukushima Diiachi plant are still not known. The total amount of radiation released is also not known for certain, and the impacts on human health and the environment, and hence the likely number of deaths, cannot be determined with the information available.


3. Mayak explosion - Russia (ex-URSS)

200+ fatalities – Mayak or Kyshtym nuclear complex waste storage tank explosion,(Chelyabinsk, Soviet Union, 29 September 1957), figure is a conservative estimate, 270,000 people were exposed to dangerous radiation levels. Over thirty small communities had been removed from Soviet maps between 1958 and 1991.

4. Windscale fire - United Kingdom

33+ cancer fatalities (estimated by UK government) – Windscale, United Kingdom, October 8, 1957. Fire ignites plutonium piles and contaminates surrounding dairy farms. Windscale was an air-cooled graphite-moderated reactor with no containment structure. A significant contributing factor was that the graphite caught fire.

5.

17 fatalities
August 2000 – March 2001. Patients receiving treatment for prostate cancer and cancer of the cervix receive lethal doses of radiation.

6. Radiotherapy accident in Costa Rica
13 fatalities – Radiotherapy accident in Costa Rica, 1996. 114 patients received an overdose of radiation from a Cobalt-60 source that was being used for radiotherapy.

7. Radiotherapy accident in Spain

11 fatalities – Radiotherapy accident in Zaragoza, Spain, December 1990. Cancer patients receiving radiotherapy; 27 patients were injured.

8. K-431 Submarine - Russia
10 fatalities – Soviet submarine K-431 reactor accident, August 10, 1985. 49 people suffered radiation injuries.

9. Radiotherapy accident  
10 fatalities – Columbus radiotherapy accident, 1974–1976, 88 injuries from Cobalt-60 source.

10. K-27 Submarine - Russia (ex-URSS)
9 fatalities – Soviet submarine K-27 reactor accident, 24 May 1968. 83 people were injured.
