plutonium. plutonium. pu239. and you know what plutonium will do? plutonium as well as uranium 235 will undergo fission when a neutron taps it. and so this is used for power production. u235, used for power production. historically, when the bombs were dropped back in world war ii, the bomb that devastated hiroshima was a uranium 235 bomb. you know how much uranium 235 was left after the bomb was detonated? almost none. the united states shot its arsenal, one bomb, none left to speak of. you know what the bomb that hit nagasaki was? plutonium. plutonium. does the same thing. plutonium is made from uranium 235--238, very plentiful, but you got to bombard it with neutrons so you can make it. you can make plutonium. now, why do we get this 200 million electron volt? that's what i want you to know. you--all you guys know that uranium splits into elements and you get a lot of energy off, and you all know that the neutrons will cause new reactions. niceroony, that's junior high school knowledge, yeah, anyone takes a science course. what we wanna know is w

some of the plutonium is spread all around so the people from the town left. made them go through a chamber where they washed them down with anti-radiation stuff. they went into that chamber leaving their clothes behind, their possessions, everything, just their bodies came out the other side of the chamber. for many, many years, at least 25 that i know of, the people from the town were given urineanalysis to see if they were infected by the radiation. what the u.s. then did was basically go in there and -- with the guidance counselors saying we're picking up radiation, and they went in there, and they wore all kind of special anti-radiation suits, went in there, and they bulldozed the entire town. they -- all the houses, everything in the houses, and three feet down, tomatoes and three feet below the tomatoes, was all bulldozed and puferlized in terms of the houses, and all of that stuff was put into thousands and thousands of barrels, special barrels made in italy and brought there for that occasion. figure i have a 5500 barrels, and they were loaded aboard

weapon it could be by highly enriched uranium, whereas the last two were believed to be through the plutoniumoute. so this is very problematic, not just because north korea having lots of fissile material is a bad thing, but north korea has a tradition of selling off anything that can garner hard currency on the open market. >> and though the soviet empire is a thing of the past, china is echoing the aspirations of its predecessor. >> there's no question that we're going to face a very serious challenge in the years to come, dealing with a rising china that wants to be dominant and hegemonic in its own region, wants to control sea lines of communication, wants to control the south china sea. and we have allies who stand to lose from that and look to us for support. i think that's the likeliest area of actual conflict. >> the pentagon will often say and right now the u.s. spends something like 4, 5, 6 times what china spends on its defense spending. and the big question then becomes what is china's intention?

reuse and requirements on plutonium pit production. the bill does -- the bill also does not con sane some very controversial issues we had there in the house version in particular that would have weakened our health, safety and security across the nuclear weapons complex and really undermined what i believe is our federal oversight role. these steps will help us to sustain the deterrent force we need to meet 21st century security challenges without overspending or compromising the safety of our workers or the public. there's some concern still. $6 billion plutonium fa ill silty remains part of our immediate plans even though the department of defense, the u.s. strategic command, the national nuclear security administration, and the national laboratories all agree that we don't need this facility for at least another five years and they prefer more cost effective ways of doing this but unfortunately, this was continued in this bill. and many other provisions. thank you again, lastly, i want to thank all of the staff for having helps us,

they are concerned about the security of records grade plutonium at the site after iran unexpectantlye reactor last october. that was raising concerns over the possibility that something might be going wrong there and of course what exactly iran is doing. the journal reported today that the pentagon's suite of drones is operating over the persian gulf and doing extra missions over the coast. in november an iranian fighter jet or several jets pursued one of the drones, firing at it but missed it. the u.s. confirms it was our drone but it was not doing any surveillance on bushear. much more tomorrow on that store row tomorrow. jon: two of america's bussist reports are at a grinding halt. something in your home almost certainly came through them. rick leventhal live in the newsroom with the latest on that. >> the strike was sparked by clerical workers who virginia been wrangling for a new contract for two and a half years, they claim they are outsourcing well-paid jobs. dockworkers refuse to cross the picket lines resulting in the shut down of ten terminals at los angeles-long beach. the
