How did the radiation get out of the nuclear power plant in Japan?

Question:

Answer:

The fuel rods encased in zirconium alloy began to overheat when the cooling system went off line. The Zirconium alloy began leaching the oxygen from the water it was in leaving the molecule Hydrogen behind. Hydrogen explodes, which is what happened causing a hole to the outside. From there radiation leaked out carried by the air currents.
