Japans Nuclear Disaster - Not Good‏

http://www.csmonitor.com/World/Asia-Pacific/2011/0315/Radiation-exposure-How-big-is-the-threat-in-Japan

On Tuesday, a fire broke out at the fourth reactor and there were reports that the storage pond, holding spent fuel rods, had boiled over. (Not good)

more radiation was released as a result and that "now we are talking about levels that can damage human health." (Not good)

radiation close to the reactors measuring four times higher than the maximum allowable limit of 100,000 microsiverts per hour (Not good)

As of Monday, the plant was emitting as much radiation in one hour as it normally would in six months (Not good)

"The possibility that a large amount of radiation has been released is low." (Huh?)

"If the fuel in the reactors overheats and melts through the bottom of the steel containment vessel, it may reach an underground water source and create much more dangerous radioactive steam." (Not Good)

One of the spent-fuel pools where the used radioactive rods are normally cooled has already released steam. The condition of the pools and their cooling systems after the hydrogen explosions are unknown and experts say that if the pools have been compromised, they could release more radiation than a reactor meltdown. The pools have far more radioactivity than the reactors, and do not have the protection of a containment building. (Not Good)

plutonium particles found in MOX are far more harmful than other emitted elements. With a reported three yards of a MOX fuel rod exposed in one of the reactors, these plutonium particles may be mixing with escaping gasses. (Not good)

IAEA inspector and Swiss nuclear engineer, said he doubted a complete meltdown would happen and that a partial meltdown, such as those that have happened already, "is not a disaster." (Huh? Not a disaster. Really? That is good to know because it all seems like a disaster to me.)

given the potential risks, authorities have evacuated 210,000 residents within a 13-mile radius.
