Study Notes

Chernobyl Disaster

Problems in the area were economic and psychological, not directly health-related.
Dr. Mikhail Babanoy, a radiologist, said the scientific secrecy by the Chernobyl hobby.
A blogger wrote about the exclusion zone based on personal experience.
People thought it was amusing to visit Chernobyl at first, but the area became unsafe and dangerous for animals and humans alike.
Workers at the plant attempted to cool the plant's turbines with coolant, but were unsuccessful.
The loss of power from the plant's family of diesel generators caused damage.
