What Happened?
In 1986 a generator in a nuclear power plant in Ukraine exploded
The accident was caused from a combination of flawed reactor design and under-trained personal
What Happened Continued
The reactor’s fuel cell was putting out too much heat for the coolant to handle
Radioactive debris spread over a 30 kilometer radius from the generator
In all, a total of 14 EBq of radiation was released into the environment
Over half of it spread by un-reactive gaseous elements
What Happened Continued
Over the next three months following the accident, two died on the day of the accident and 28 more died from radiation poisoning
The resettlement of the contaminated areas is an ongoing process
Contamination of water sources was quickly brought down to safe levels through dilution, and absorption of radionuclitides in bed sediment

Who Was Impacted?
Chernobyl was located in the Soviet Union, what is now Ukraine
Iodine-131 and caesium-137 were the two main contaminants in the accident
Iodine-131 has a short half life of eight days
Caesium-137 was the main concern for the contaminated area with a longer half life of 30 years
Consequences
Any buildings or agriculture in a 30 kilometer radius was contaminated with radioactive nucleotides from the explosion
The area around Chernobyl was deemed uninhabitable and the agriculture contained too much radioactivity to be safely consumed

Consequences Continued
The World Health Organization(WHO) conducted tests to analyze the effects that radioactive exposure had on a person’s health
WHO found that the scientist who originally contributed disease to overexposure to radioactivity had been incorrect

Consequences Continued WHO found that the exposure to radioactive
waste had not been the cause of the diseases
People were exposed not only directly to the radiation, but the radiation was also in the food that they ate Bioaccumulation caused the animals in the area to obtain radiation.

The Lingering Effects
Pripyat, within the 30 kilometer radioactive radius of Chernobyl, is still uninhabited by today
Pripyat is considered an unofficial nature reserve

Chernobyl Today
The Ukraine government plans on opening the sarcophagus over Chernobyl reactor 4 to allow tourists to learn about the disaster.
