The two isotopes you'll find around the contaminated area Iodine-131 which has a very short half-life of 8 days and Cesium-137 which has a half-life of 30 years. They are both dangerous in their own right for different reasons. Iodine can be readily absorbed into the body and children are typically more vulnerable to adults over the long-term. However because it decays so quickly it's not much of a concern. Cesium which is the real concern due to it's lengthy half-life and properties. It's highly toxic and you only need about 40-50 μg/kg for a lethal dose. Also it's water soluble so if it works it's way into the water supply you've got a whole new disaster to deal with.

In regard to the coffins and future containment it's something they are not too sure of yet. The reactor vessels were not significantly breached and the vast majority of the reactor fuel might still be contained within them making cleanup much easier. We'll have to wait and see what happens to see if they are going to create a Zone of Alienation like Ukraine did, but it's unlikely at this point due to the amount of materials released and the information available to use about the integrity of the vessels.

Oh and while there are many intelligent people in this forums there are several who quite frankly are prone to panic, like pretty much all people, with subjects they don't understand. Go browse the first couple days of posts in this thread and read what some people have asked/said. The posts in regard to that radiation dispersal map are proof enough.

Reputable is official numerous sources, subject matter experts and analysts, etc. Basically if its valid information you'll quickly find it works it's way through most major news outlets and agencies. If the information can't be verified it doesn't really have any value. Speculation can be useful in regard to planning and general discussion but at the end of the day it doesn't really add anything to your understanding of an incident such as this..
I def took a look in to his history and he was right about internet caps, right about the reactors, and he definitely never said everyone on the west coast was going to die, he raised valid questions about our food and air quality and backed it up with "sources", and u really need to do some homework on gmo foods especially with reports this week claiming scientists are linking gmo to the bee deaths http://www.globalresearch.ca/index.p...xt=va&aid=8436
http://www.globalresearch.ca/index.p...912&context=va
these are two out of a thousand problems/articles about gmo, i just see someone attacking a person, where are your sources for discrediting him/her? that would be a better way of debating him im sure

Heard in the news yesterday that radiation had reached up to 4000 mSv/h in certain areas - if true, that's very, very bad. That kind of radiation will cook you dead in two to three hours at most.

Apparently, the highest radiation ever reached there is 204 Sv/h... (no, I did not forget a milli prefix)

When i was in school in science class we watched a movie based on a true story about nuclear powered submarine that had it's core melt down. Some of the guy on board tried to weld some of the casing and cooling pipes, one puked out his own lung. it ended with one or two or even three dudes dieing and the sub was sunken and left rot. I was told it had a half life of SEVERAL HUNDRED YEARS? so is that how long it will stay? thats also why I don't thin Chernobyl is ready. I am so off/wrong that.. face palm?

A half life of, say, one year would mean that half the matter would have radiated away after a year. That is,
(Note that the products of this can also be dangerous)

For example, Uranium-238 has a half life of about 4.5 billion years.
A slab of 10 kg of U-238 would, after 4.5 billion years, only weigh 5 kg, whilst the rest would've decayed to Thorium-234 and alpha particles (helium ions).

Yes, that was K-19: The Widowmaker. Very emotional film. @Chernobyl, AFAIK they are planning to build another shell around it, excavate the dangerous insides and dispose of it more safely. The surrounding radiation really isn't bad though; there are now tourism trips through Pripyat IIRC.

Yes, they are planning to build another shell because the building might collapse and spew up lots of radioactive dust. That would be bad.

Yep the new shell is expected to be complete and in place by 2014-2015. As for the Zone of Alienation it is open for tourism now. It costs about 160 USD for an official tour with one of the tour agencies that are allowed to conduct the trips. The background radiation really isn't bad at all. You get more on a transcontinental flight then you do during a couple days in the Zone. However you need to be careful to not kick up dust/dirt and should avoid vegetation inside the Zone because of the high concentrations of Cesium still on the site. I'll be going there sometime this August! Have to get there before the new shell is in place and that iconic image of Reactor 4 is gone.

for all the people out there that believed the main stream news and didn't want to admit this, here you go.

"no , your a fear monger they didnt meltdown."

They are still smoking to this day....

U.S. Has yet to release official radiation numbers from the drones, and we have radiation flying around the plant and background radiation is set to double or triple because of this.

100s of times safe levels found in us milk, and the epa raises safe radiation levels. But i bet most of you weren't aware of any of this huh?


But hey, its no big deal.

The new age , gota love em.

I SHOULD PULL UP CLIPS FROM YOUTUBE, ON THE MAIN STREAM PROPAGANDA.

"no word of offical meltdown"
"appears situation is under control"
"1 may have melted down"
"prevented reactor from melting down"

than the war in Libya started and this disappeared from the news.

Maybe this will help people understand how the real world works and they will stop being so dang gullible.

But than again, maybe no one cares about this new article and they dont understand how huge this announcement is. Anyway its the past its all forgotten now, just like everything else.
The wars , broken econ, etc.....

I can play you video clips of Obama saying we were only gonna be in Libya for 2 weeks, and a "no fly zone"

Guess what, we are gonna be over there all the way into next year.
Good job guys, good job.

Morons.....

Just had to rant a lil guys, dont take it personal.

Sources on radiation in us milk

http://online.wsj.com/article/SB1000...749626458.html

Radiation in rainwater
http://www.huffingtonpost.com/2011/0..._n_841188.html

http://video.foxnews.com/v/4595729/c...or-radiation-/

I could really post non stop , 1000s of news articles.

Its very simple

Go to google.com
and click on the news tab
None of those sources regarding the milk says anything about it being 100's of times more than the safe level, which you claimed. Give a source that backs up your claim that the EPA raised the "safe level" of radiation, and that the radiation in milk is 100's of times the previous safe level.

It's crumbling and if it continues to crumble there would be a higher chance of the so called 'Second Explosion'. They haven't even begun building the other shell. The Sarcophagus was designed to Last for 20-30 Years as a Temporary measure. However they haven't replaced the Sacrophagus and it is rapidly crumbling not only from rust but from the weakining structure due to rain and various weather elements.

Not with the way the current events are happening. The new Shell won't be in place anytime soon. There are constant Red Tape and delays associated with the Shell. The Sarcophagus will crumble by the time they put in place the new shell. Oh and for the prices I can honestly say that you are being horribly ripped off. They put special Tourist prices like those for you. The real prices aren't even close to that.

I was actually planning to visit The Zone of Alienation especially the KPP Dityaki however I've had to delay and post-pone these plans several times.
