Accidents from experiments

  1. 1. Andromahi Gati Maria Efthymiou Natasa Noussi Anna Konstantakou Giannis Filippaios January 2016 1o Geniko Lykeio Pallinis , Greece
  2. 2. Accidents from experiments Bad effects in the environment
  3. 3. Chernobyl The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant.An explosion took place and fire released large quantities of radioactive particles into the atmosphere, which spread over much of the western USSR and Europe.
  4. 4. The environmental effects Groundwater Radionuclides with short half-lives decayed away long before they could affect groundwater supplies. Longer-lived radionuclides such as radiocaesium and radiostrontium were adsorbed to surface soils before they could transfer to groundwater.
  5. 5. The environmental effects Flora and fauna After the disaster, four square kilometers of pine forest directly downwind of the reactor turned reddish-brown and died, earning the name of the "Red Forest”.
  6. 6. Toxic algae The last few years there has been an issue which concerns many scientists in the area of the Mediterranean sea. From the 1926 there have been two new kinds of algae in the sea. Scientists of course noticed them a bit later.
  7. 7. It was determined that the first one was leaking out from the exhibition aquarium of Monaco by accident and it is called CaulerpaTaxifolia. The second one which is called Caulerpa Racemosa, has escaped from the Red Sea.
  8. 8. These two kinds of algae are considered a threat to our environment because they are spreading extremely fast and because of they structure they cover every other kind of sea plant that is in their way. So the consequences are decrease of the biodiversity in the sea and overturn of the ecological balance.
  9. 9. Nevada’s Atomic bomb In 27 January 1951 at a dry lakebed in Nevada the first air dropped nuclear device was dropped for testing purposes. This test was a part of an American nuclear test series called Ranger which was consisted of five air dropped nuclear tests.
  10. 10. In the 1963 an agreement which banned all nuclear tests in the atmosphere, underwater and in outer space was voted because of the obvious effects of radioactivity in people’s health. Until today the scale of harm is uncertain.
  11. 11. Bhopal On 3 December 1984, a Union Carbide India Limited pesticide plant in Bhopal leaked around 32 tons of toxic gases which led to the worst industrial disaster to date.
  12. 12. The impact of the disaster They continue to this day in terms of psychological and neurological disabilities, blindness, skin, vision, breathing, and birth disorders. The soil and ground water near the factory site have been contaminated by the toxic wastes.
  13. 13. Tokaimura nuclear accident Tokaimura nuclear accident indicates the nuclear disaster which occurred on 30 September 1999, resulting in two deaths.
  14. 14. Effects • Dozens of emergency workers and nearby residents were hospitalized • Hundreds of thousands of others were forced to remain indoors for 24 hours;
  15. 15. Effects • 39 of the workers were exposed to the radiation. • At least 667 workers, emergency responders ,and nearby residents were exposed to excess radiation as a result of the accident.
