How Bad is depleted uranium?

Recommended Posts

Anyone know first hand? I have family in Iraq who has a high possiblity of being exposed to this substance. And frankly I dont know which articles to belive, the ones that claim its harmless, or the ones that claim it causes horrid birth defects and cancer.

I don't know first hand, but the WHO page seems to minimize DU effects, yet it says
Quote

The behaviour of DU in the body is identical to that of natural uranium.

which doesn't sound good to me. Natural Uranium is known to cause cancer as I understand.
Here is an article that describes an increase in DU in Europe since Gulf War 2. http://www.timesonline.co.uk/article/0,,2087-2047373,00.html
Of course, they write it off and call it a coincidence.
A Scottish article http://www.sundayherald.com/32522

I have heard rumors that the Gulf War Syndrome is actually radiation poisioning from DU.

I remember reading that there were some high radiation readings from parts of Baghdad, couldn't say where. I don't think I'd want that stuff in my breakfast cereal.

Just about all heavy metals have some toxicity associated with them. Depleted uranium is about as heavy as you can get.

It probably ain't as bad as some say, but you may also note that it is not included in any reputable multivitamin.

I've handled the stuff at Boeing a couple times, they use it for counterweights on flap assemblies in commercial jets. The stuff is UNBELIEVABLY heavy ! Only messed with it 2 - 3 times, had a really healthy kid after that, so far 18 years later everybody's just fine.

as a chemist:

depleted uranium is used in shells because it is extremely dense and it does not have the radioactive characteristics of non-depleted uranium.
the fact that it is dense enables it to penetrate heavy armor. more acurately, you can concentrate a relatively large amount of mass in a small round which gives you a shit load of momentum in a projectile of low surface area. it's like shooting a 20 lbs. bb at a sheet of paper.

the term "depleted" means that the uranium atoms have undergone radioactive decay already. depleted uranium is safe to handle because there is no risk of harmful radiation. i think that the use of this material came about because scientists wondered what use there was in uranium rods that were spent in nuclear reactors. once they're "spent", you have depleted uranium and it's hella dense without the radioactive down side.

ok I can understand that but what about this line from the WHO website

# DU, consequently, is weakly radioactive and a radiation dose from it would be about 60% of that from purified natural uranium with the same mass.
# The behaviour of DU in the body is identical to that of natural uranium.

is 60% enought to worry about ? does that mean that it would take double the deadly does of regular uranium to kill you? any idea what the lethal dose is?

very true. osmium and iridium are actually the most dense, stable materials but, depleted uranium is far cheaper to isolate for other uses than either one of the first two and it's about twice as dense as lead. complete uranium decay yields lead but, that process takes a very long time. the half-life of uranium-238 is 4.5 billion years.

that is all true. especially, the second part notes that if you ingest DU, the effects would be similar to non-DU. this is because your skin protects you from alpha radiation, which is how uranium initially decays into protactinium. the technical aspects of radiation apply here. the easiest way i can tell you that depleted uranium is far less harmful than uranium is that the dosage of DU is far below that of non-DU. right now, your body is being bombarded with radiation as is everything on the earth (radioactive elements aren't just the ones at the bottom of the periodic table. carbon-13 is radioactive, is present in everything that contains carbon, and is the basis for carbon dating. many, many elements have radioactive isotopes). if the concentration of radiation gets too high on a living organism, radiation poisoning sets in. you can do research on this topic to learn more, and there is alot to learn, but, it's very interesting (i think). read about alpha emmision and beta emmision. both are processes by which uranium decays (eventually) into lead-206. i didn't look up what the "deadly" dose of uranium-238 is to a human but, that info is out there. however, uranium-238 is not depleted uranium; depleted uranium is a mixture of uranium, protactinium, and lead which is far less radioactive than pure uranium. happy hunting and enjoy the reading.

I guess that is about like saying light cigarettes aren't as bad for you as full flavor. Poision is still poision, even lighter versions of it.

You claim it is fairly safe. I assume this means as long as it isn't airborne, which DU dust particles is airborne, and being breathed in by everyone in Iraq right now, and upwind to Europe too.

Does anyone note the fact that the thing about DU is they found a use for this industrial waste. Not only found a use, but a way to make money off of it! Very similar to the poision, flouride- another industrial waste, which is being added to municipal water in most cities

The Wikipidia definition of DU is interesting.
http://en.wikipedia.org/wiki/Depleted_uranium
Says that during processing they have to monitor and filter airborne particles. Do you reckon they are filtering the particles in Iraq? What about the poor folks whose land we are poisioning forever? The DU dust will get into their crops, water supplies, everything. So tell me again how safe this stuff is for our troops?

Can you assure the reader that with all these shells we dropped that we wouldn't have kicked up an ass of dust to be breathed in by the Iraqis and our troops too. I think not. All you can do is say it is safe as long as it is not ingested. Which doesn't mean much since you can't see it to avoid it.

Do you have a confirmed radioactivity plot of that? I'd like to see the data, if you can provide it.

Thanx for the info, I really appreatate the time you took to awnser me.
I found this info on DU shell impacts.> here

http://serendipity.nofadz.com/nato/du.htm


Bullets, shells and missiles tipped with radioactive depleted uranium made every weapon in Iraq's arsenal obsolete. The higher weight of DU shells allows American tanks to shoot twice as far, giving them a range of two miles.

During the [1991] Desert Storm terror campaign at least 944,000 rounds of DU ammo were fired from American A-10 Warthogs all over Iraq and Kuwait. The A-10 is an aircraft built around a 30mm, 7-barrel gattling gun that can spew 3900 rounds per minute.

When a depleted uranium tipped shell strikes a tank or armored personnel carrier it easily penetrates the armor and burns the crew alive. The impact also vaporizes the depleted uranium, creating an aerosol of radioactive heavy-metal particles which can spread as far as 190 miles on the wind.

When inhaled or ingested, the depleted uranium particles cause chemical and radioactive damage to the bronchial tree, kidneys, liver and bones. Cancer often results, and the effects can even include genetic damage.

The Dutch Laka Foundation estimates that the United States terror campaign left behind 300-800 tons of radioactive waste from this [depleted uranium] ammunition all over Kuwait and Iraq — poisoning the air, the land, the water and the people everywhere.

Afterwards, wherever the depleted uranium firing had been concentrated, there were cancer epidemics among Iraqi civilians living nearby. In the ten years since then, sanctions, polluted water and depleted uranium together have killed somewhere between 1,000,000 and 2,000,000 Iraqi civilian people. At least 600,000 of the dead are children. Cancer rates have quadrupled in areas of southern Iraq bombed by the American and British state terrorists.

All uranium isotopes are radioactive. DU is just less radioactive than natural uranium because the most radioactive isotopes have been removed. DU is still radioactive, however, (U238 is an alpha emitter and its first daughter decay product is a beta emitter), which means it is most hazardous when inhaled as dust, when it can cause lung cancer. There are also chemical toxicity effects common to all heavy metals.

Please be careful what you read. While this article probably isn't 100% inaccurate... you read stuff like this

During the [1991] Desert Storm terror campaign...



... and you have to get an idea of what the motivations of the people writing it are.

Maybe stick with the stuff that is more scientific in origin and then come back to the protest sites to see what some people are saying.
Oh, hello again!

DU is is very bad unless cooked properly, it should never be over cooked and should be cooked with a garlic and onion sauce (my preference you can experiment). the wine will some what depend on the sauce but most prefer a light white wine.
you can pm me for recipes if needed!:)

don't eat it
don't sniff it
don't snort it
don't smoke it
don't inject it
don't put it in your eye
don't put it in your butt

other than that it's fine ;)

You can have it good, fast, or cheap: pick two.

Cooking U238 turns it into Pu239 which is much much nastier:P:P:P
