A specific isotope of cesium has been linked to nuclear weapons, and not Chernobyl—the previous suspected cause.

After atomic bombs were dropped on Hiroshima and Nagasaki, nuclear physicist Katharine Way persuaded the world’s greatest physicists to contribute essays to a book opposing nuclear weapons

Power, that would be the first good news in a series of awful press releases, each one getting worse than the other. but we're not out of the woods because it's a race against time. they want to restore power before it's so radioactive that workers cannot go in. and that means that there could be a meltdown and finally a breach of containment. breach of containment would make it a class 7 accident, like chernobyl. uncontrolled releases of radiation into the air. class 7. >> and what results? if this goes class 7, what will we see in japan and in the surrounding area? >> you will see enormous q...

Northern japan. japan, their integrity could be threatened so the main thing is to stop it. we can debate secondary and long term effects later, but stop the pleading. >>greg: and plutonium is more dangerous than uranium? >>guest: yes, and realize unit three has lost fuel containing plutonium so we have a cocktail of very dangerous fission products and at chernobyl 25 percent of the core came into people's backyard. greg plutonium has a 25,000 year half-life. uranium is 700 million years. >>guest: we are talking about the life of the solar system, four billion years for uranium. a meltdown is ...

Meltdown. the danger is better described as a zirconium fire. the fuel rods are suspended in water and as long as they are in water they can be kept cool. they have a level just as any spent fuel has. if they are exposed toç air an also to steam then there is a chemical reaction of steam that creates hydrogen and also weakens the zirconium clad. that process allows the fission products, the nasty stuff, to escape from the fuel rods and to the atmosphere which then get lofted up into the air in this smoky fire. that plume is incredibly radioactive. >> could it spread to the other reactors? is...
