As radiation readings in Japan reach their highest levels since the Fukushima Daiichi nuclear power plant meltdowns, we look at the beginning of the atomic age. Today is the 66th anniversary of the U.S. atomic bombing of Nagasaki, which killed some 75,000 people and left another 75,000 seriously wounded. It came just three days after the United States dropped an atomic bomb on Hiroshima, killing around 80,000 people and injuring some 70,000. By official Japanese estimates, nearly 300,000 people died from the bombings, including those who lost their lives in the ensuing months and years from related injuries and illnesses. Other researchers estimate a much higher death toll. We play an account of the 1945 atomic bombing of Nagasaki by the pilots who flew the B-29 bomber that dropped that bomb, and feature an interview with the son of Pulitzer Prize-winning journalist George Weller, who was the first reporter to enter Nagasaki. He later summarized his experience with military censors who ordered his story killed, saying, "They won." Our guest is Greg Mitchell, co-author of "Hiroshima in America: A Half Century of Denial," with Robert Jay Lifton. His latest book is "Atomic Cover-Up: Two U.S. Soldiers, Hiroshima & Nagasaki and The Greatest Movie Never Made." [includes rush transcript]"
