When the writer Henry Shukman first heard about the Chernobyl Exclusion Zone, he was intrigued that even though it had been the site of a nuclear reactor disaster, it was Europe's largest wildlife refuge. For more than 25 years, only a few humans have been allowed to enter the 1,600 square miles of land around the nuclear reactor there. But Shukman tells host Dick Gordon about a family who returned to the exclusion zone. They and others who have done the same are known as "resettlers."
