  1. By: Brooke Kelly APES Kyshtym Disaster

  2. What was the Kyshtym Disaster? Kyshtym Disaster was a radiation contamintation incident. This was a level 6 disaster on the “International Nuclear Event Scale”. Third most serious nuclear accident ever recorded

  3. Where and When? Accord in the town of Ozyorsk, near Mayak plant September 29th, 1957 Nuclear Fuel Reproducing Plant in Russia

  4. Why did the explosion accure? The cooling system in one of the tanks that was containing 80 tons of liquid radioactive waste that failed and was not repaired, the temperature increased causing evaportation. A chemical explosion was the result of the increased temperature.

  5. The Effect of the Explosion It released 20 Mci of radioactivity, contributing to the pollution of the Techa River. A radioactive cloud was formed, moving towards the north east.

  6. The Effect of the Explosion The contamination created a long term effect on the area within 800-20,000 square km. The current area is referred to as “East-Ural Radioactive Trace”.

  7. Evacuations Directly after the disaster 22 villages were exposed to the radiation 10,000 were evacuated Many were immediately evacuated

  8. Aftermath The reasoning for the evacuation was not stated to the public 6,000 deaths occured because of the disaster 200 deaths because of cancer

  9. Aftermath 10 days later the goverment decided to plow 515 acres of radioacitivy land, so they could restart their agirculture use.

  10. Currently Today In Ozyorsk, the radiation level is safe for the public again but the “East-Ural Radioactive Trace” is still contaminated.
