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

Where and When?

● Accord in the town of Ozyorsk, near Mayak plant

● September 29th, 1957● Nuclear Fuel Reproducing Plant in Russia

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.

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.

●

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”.

Evacuations

● Directly after the disaster 22 villages were exposed to the radiation

● 10,000 were evacuated● Many were immediately evacuated

●

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

Aftermath

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

Currently Today

● In Ozyorsk, the radiation level is safe for the public again but the “East-Ural Radioactive

Trace” is still contaminated.
