Chornobyl's exclusion zone covered small part of contaminated area only. My parent's home is in contaminated area, but nobody was evacuated. Cancer rate is 2.5x larger at average in four regions of Ukraine, which are near to Chornobyl. I saw 6m (20 foot) wide circle of dead grass at about 800m from my parents home, where a hot particle landed. Both my neighbors are died because of cancer. I live in clear region, but my lungs was very radioactive for few years, because of my visits to parents.
