Japan's nuclear crisis continues to grow more dire. The rating of the exposure has been raised from 5 to 7 and is at the highest level we've seen from a plant under the International Atomic Energy Agency. With the continued amount of radiation being leaked, there are fears that Japan's nuclear disaster could reach Chernobyl level catastrophe. What can be done to contain the radiation?

Workers are still working on cooling the cores and say that the cores are quite safe right now as they are surrounded by containment vessels. Most of the radiation that leaked happened at the beginning of the disaster and has since slowed. The evacuation zone surrounding the plant is at a 12 mile radius.
