First, the nuclear power plant CANNOT explode, and it didn't. What has apparently happened is that after the earthquake on March 11, 2011, the power plant was SCRAMMED, which means an emergency shutdown procedure. This prevents the nuclear fission reaction from continuing.

It is the heat of nuclear fission that boils the water into steam, and the steam turbines generate electricity. But even after the reactor is shut down, there is still LOTS of heat in the core, and you need electricity from some other source to power the pumps that circulate the cooling water. The nuclear power plant included a number of auxiliary diesel generators to generate enough electricity to cool the reactor core, but the diesel engines were disabled by the tsunami. The tsunami also destroyed all of the electrical power wires in the area, so with no power being generated by the reactor and no electricity available to run the coolant pumps, the reactors overheated.

We still aren't sure what has happened, but some of the uranium fuel rods appear to have been partially melted, and some radiation has been released into the environment. Some radioactive iodine-131 has been detected in the water supplies in Tokyo, but at very low levels. Iodine-131 has a half-life of only 8 days, so it is pretty radioactive, but it will all be gone in just a few months. However, radioactive iodine can cause thyroid problems, especially for infants, which is why the Japanese government has asked people not to drink the tap water. An "activated charcoal" water filter can remove even trace amounts of iodine from the water.

One of the problems with measuring radioactivity is that our detectors are SO GOOD these days that even very low - as in, "harmless" - levels of radioactivity can be detected. So far, nobody has been sickened by radiation, although several technicians have exceeded their "yearly safe allowances" for radioactive exposure.

If you are in the United States, you are certainly at a much greater risk of having an airplane crash on your house than you are from radiation for the leaking Fukushima Daiichi power plant.
