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.
