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."
