How much of the really nasty isotopes have decayed away by now? Yes Chernobyl was a disaster, but by now, most of the higly radioctive fallout has decayed. As for the dangerous alpha-radiation emitters-how bad is that in the Chernobyl area? I also understand that the RMBK reactor design is not especially dangerous-the massive graphite mass can absorb a lot of heat. The problem was that the reactor operators had turned off the safety systems, and diabled the cooling pumps. they then throttled down the reactor, to the point where the power output became unstable.
ralph124c if this page is correct in what it says, it is worse in places now than it was just after the disaster. This page gives explanations of the various kinds of radiation. Here is a Wikipedia article on Americium 241.

The sheep farmers in North Wales ( no jokes please!) are still feeling the effects of this accident. Because of the rocky nature of the soil, the radioactive contamination is still high. They have to check every animal with a geiger counter. If the reading is too high they send these sheep to somewhere that has “clean” pasture . After a few weeks of feeding on this non-radioactive grass , the contamination is disappears from their bodies.

Are you sure this is because of Chernobyl? Why would North Wales be contaminated from Chernobyl? Can you give a link to where you got this from?

Adding to be clear, Americium 241 emits gamma radiation.

Now all you have to do is provide some scholarly links that show the gamma rays released by the Americium 241 involved are worse than the Americium 241 in my smoke detector.
Samclem the link Cowgirl Jules provides backs up what Rayne Man says. The poison winds went far, and affected several parts of Europe. The U.S. was able to detect radiation from Chernobyl, though I am not certain at this point in time as to when. (I am thinking it was May 1st, but the date might have been May 9th.)

Well, even you must grant that the miniscule amount found in your smoke detector is not the same as the amounts in the soil and plants of the areas that got the heaviest fall out, and that now are saturated with Americium 241. I think your analogy is flawed. :dubious:
[QUOTE=Cowgirl Jules] Here’s an interesting photo essay.

That´s depressing, it makes you want to scream and curse those idiots and their stupid “experiment”; what were they thinking!
It was like causing a gas leak and saying, “Now I´ll light a match and see what happens”. And they did it on an uncontained reactor of all places, what were they thinking…
Now the blight of their incompetence will lay on the land for centuries and children will be born without hope for a life for generations.
Pulling up the contamination map (found on the menu) on the site Cowgirl Jules linked I see that it was on May 5/6 that the U.S. detected radation from Chernobyl, so I was mistaken as to precisely when that was earlier.
I remember exactly where I was when I heard about Chernobyl blowing up, and that’s because I was working in a trailer at the Diablo Canyon nuclear power plant at the time. I remember looking out the trailer window at the plant’s cooling towers and wishing I was anywhere else but there.

This was certainly because of Chernobyl. The radiation cloud drifted that far. As for the link , try this . Although that article dates from 2003 it is still relevant. BBC TV ran a similar news-feature just this week.
