Are we really safe from the "meltdown" of the nuclear reactor in Fukushima, Japan?

Given that the prevailing winds, which brought acid rain from China to the United States, will now be blowing radioactive particles released from the nuclear power plant blast in Japan in our direction, one wonders just what the risks might be.

I don't know just what chemical elements compose the radioactive particles which may float on the breeze to our borders. I assume that our fellow citizens will be inhaling one or more of these little nuclear weapons which will be radioactive.

I am not aware that there is an allowable or innocuous dose of such entities.

Is there anything one can do to protect oneself? I know that one can saturate one's thyroid gland with Iodine so that a radioactive iodine particle will not be "taken up" by the thyroid. I wonder what becomes of such a particle floating around in one's bloodstream? Not to mention whatever other radioactive atoms find their way across the ocean and are breathed into our lungs.

Is there some reason our leaders are not warning us to take protective action? Do they want to avert a panic? Is the radioactive cloud being monitored? I would feel better knowing that the jet stream is guiding such a cloud on a trajectory which would avoid the US altogether. But if it does rain down on our farms will some particles find their way into our food or milk!?

I have read articles in the media which suggest that distance, dilution and time would lessen the risks to us. Time! It will not take tens of thousands of years for the particles released from the reactors to reach us. Dilution! Although dosage plays a significant role I do not relish the prospect of imbibing even one radioactive particle which might be enough to do harm (euphemism for to cause cancer.)

Appreciate any thoughts or wisdom you may have.

You're surrounded by radioactivity already. In my opinion it mainly boils down to the % change in background radiation, that's the interesting number to look for. But also radioactive iodine is concentrated by the thyroid.

Radioactive contamination found on 17 U.S. Navy crewmembers in Japan Read more: http://www.nydailynews.com/news/world/2011/03/14/2011-03-14_17_us_navy_crewmembers_exposed_to_low_level_radiation_in_japan.html#ixzz1GZvROjZo

"For perspective, the maximum potential radiation dose received by any ship's force personnel aboard the ship when it passed through the area was less than the radiation exposure received from about one month of exposure to natural background radiation from sources such as rocks, soil, and the sun," the Navy said.

Could just drop a tactical nuke - that would put an end to any lingering chain reaction.

Shane:

My understanding is that the "problem" is from the spent fuel rods which should not be on the grounds,

It is their exposure to the air that creates the release of the more dangerous radioactive emissions such as cesium which has a half life of, I believe, twelve (12) years.

There is an inherent instability with boiling water reactors of the design used here in the U.S. and in Japan. If there is a loss of coolant either in the reactor vessel itself or in the storage pools that must be made up immediately (within 24 hours) or the thing will become a runaway. Any attempt to cool the fuel rods when at full melt will only produce superheated steam which will carry radioactive material with it up and away thus spreading the radioactive contamination. The problem is a positive action must be taken to prevent this in a timely fashion. If it is not done, the thing runs away (I do NOT mean it goes critical like an A-bomb). The kind of uranium used at these plants cannot go critical, but they can produce a great deal of heat (which is what makes them useful to boil water to run steam turbines).

Right, but with the control rods in place, the emmissions should stop from the uranium. Part of what I don't understand is what keeps the heat going...cesium and other byproducts?

Another question I was mulling is why they would put something that reaches a melting point of 3000 degrees would be put into something that melts at 2200 degrees. Other than there's nothing safely usable that melts at hotter than 3000.

Meanwhile, engineers hard at work YET AGAIN solving problems lawyers, politicians, ARI PHILOSOPHERS, and fascist CEO's can't:

One of these decades they should make it a requirement that one be an engineer before he can be Chief Executive Officer of the United States (i.e. President), or before he can be elected to Congress.

The stupid, rich cowards are paying big bucks to get out of Japan. The problem is ignorance, not radiation. This doesn't apply to the workers on the job at the disabled plant, but why did they situate it in tidal-wave land?
