Hundreds of thousands of people who were in the area at the time of the accident are still unable to return to the places where they lived. The city of Prypiat has a population of 0, where its population had been about 50,000 before the accident. There are about 90 other communities in the Ukraine that are shut down, and probably many more than that in Belarus. Birth deformities have been noticed among those exposed to the radiation. The rates of thyroid cancer in some populations of children are four times what they should be.

The problems are not confined to the Ukraine and Belarus. Today, 24 years after the accident, there are still 369 farms in Scotland that are sufficiently contaminated that they cannot sell the sheep they raise. There are herds in Finland that are still contaminated.

The list of problems goes on and on and on.
