Is Fukushima worse than Chernobyl?
Though Fukushima and Chernobyl are both level 7 nuclear accidents, the health consequences in Japan to date are much less severe. In part, that’s because far more radiation was released at Chernobyl . The reactor at the Soviet plant was not surrounded by any containment structure, so radiation escaped freely.

How does radiation kill?
When you eject electrons from atoms you can break chemical bonds, and that’s what leads to the microscopic and macroscopic damage that radiation causes.” By breaking those chemical bonds inside our bodies, ionizing radiation can destroy or damage critical components of our cells, leading to injury, and at high enough
