Michio Kaku on Fukushima

New York's Daily News today has an interview with Michio Kaku, the physicist, about Fukushima raising the threat level to 7, equal to Chernobyl. Here's an excerpt:

"Chernobyl went through 600,000 workers, with each spending just a short time at the site to avoid radiation sickness. Everyone got a medal," he said. "Many of the workers (at Fukushima) don't even know how much radiation they've absorbed. Some of them are going to die. They've probably received the lethal amount of radiation already."

I've never heard about the 600,000 workers they cycled through Chernobyl. I'd love to read a comprehensive book about what happened there. For instance, how did this work out? Have those 600,000 workers remained healthy? And what on Earth will happen to the Japanese people who lived close to Fukushima Dai'ichi?
