Depleated Uranium problem?

    I can not be sure but those pictures at the end look fake. Meaning that those pictures probably have nothing to do with Depleted Uranium. Yes the American military used Depleted Uranium, because it makes a great bullet or tank shell. I think lead is another option, but it does not work as well and there is also lead poising.

    yeas i think the end pictures are fake, especially seeing as they have not much to do with the symptoms described.

    that was what scared me, thanks lol

    I stopped reading after "nuclear war". DU bullets are just good bullets. They are not nuclear weapons. Nuclear weapons go boom because of a nuclear reaction.

    "Mega billion" really turned me off. Unless of coures our war is in actuality costing us over 1,000,000,000,000,000 dollars or roughly 100 times our annual GDP. And i cant seem to find any professional information on that woman.

    DU is used because it has high density, is cheap ( it´s basically waste you can use ) and it´s capable of adiabatic shear when penetrating, that means the KE rod "sharpens" itself during penetration. That is opposed to Tungsten, which doesn´t have this property. Also, DU is pyrophoric, which means it may disintegrate into combusting dusk inside the target.
    DU is an alpha emitter, so radiation isn´t that much of a problem normally. It gets problematic when people inhale DU dust though as then the DU resides directly in the lungs and can cause cancer etc. .
    But even non-radioactive heavy metal is highly toxic ( at least most of them AFAIK ), so that alone may suffice to make people ill.

    Uh, NO!

    Depeleted U (0.25% U-235) is the remnant of the enrichment process. Yes it is a by-product, but it is NOT 'nuclear' waste. Depleted U is used in armour piercing shells and also highly effective armour (e.g. M1A1 and M1A2 tanks). DU is also used as counter-weights (tail section) in some large commercial aircraft.

    Natural U had about 0.71% (by weight) U-235, the balance being U-238. U-235 is fissile in a thermal spectrum, U-238 basically captures neutrons becoming U-239, which then decays to Np-239 and subsequently Pu-239. That process takes months or years.

    I and others have worked with tons of "enriched" U, and we did not need special shielding.

    SK is correct however. Uranium is a heavy metal and is pyrophoric. It does burn in air. When a U-projectile hits a target or the ground and is volatized, it disperses U-oxides in the form of dust and small particles. This is potentially as hazardous as dispersed lead or any other heavy metal.

    So Iraqis and US forces 'may' be at risk in the long term. However, this will take years of follow-up epidemiological study, and this will be complicated by the existence of other factors such as diet/malnutrition, other chemicals, unhealthy activities like smoking, and normal disease.

    The above site in the first post is a nice example the political Left lying, as usual.

    The last post promted me to move this thread to Political and world affairs, perhaps shoudl be skeptisim and debunking.

    Sure is good that the right is never wrong. :yuck:

    I stopped reading the article. Little bit much for me right now :sadface:. How much validity is there to these claims? How much of the information is true and not exaggerated?

    It´s way exaggerated to say the least. There weren´t "millions of DU tank rounds" fired in iraq. Actually, use of DU rounds by US tanks was rather scarce, for there weren´t many targets (if any) that required using this ammo.
    Nowadays the US soldier face only "soft targets" (that is, people in military speech), against whose DU ammunition is not effective.
    Oh well, and the claims that real nuclear weapons have been used in AFG tell enough about the credibility of that article.
    The article is way overdoing it, but there are issues with DU ammo. I guess some googling is good for an overview.

    /edit:
    This links seems to be pretty reasonable and covers some misconceptions and exaggerations (like "all bombs use DU"):

    Its not that the right is never wrong, its just different types of conspiracy theories come from different places: if its religous, its probably on the right. If its displaced hippies, its probably on the left.

    I guess that kinda easies my mind a little SK.

    I'm pretty sure SK is wrong though, from what I understand the M1 Abrams tanks use DU-tipped rounds exclusively. Also, the claim that "DU ammunition is not effective" against "soft targets" comes off as downright absurd to me; I can't think of any reason DU would be less effective the conventional muntions.

    I've never seen a more left leaning article in my life. This looks like nothing more than an opinion disguised (loosely) as a bunch of hard to coroberate misquoted "facts". It's an Op Ed piece! I'd have to say off the top of my head that there are other things that are more likely contributing to the health problems of our soldiers and civilians (and those pictures) than DU. IMHO it's a rather badly written article. To call it news or reporting is stretching those two definitions to their limit. :yuck:

    re kyleb:
    Nope, you´re wrong. the Abrams tank uses the M829 series of APFSDS projectiles, that´s Armor Piercing Fin stabilised Discarding Sabot. The projectile itself is a dart made of a "DU rod" with fins and an aerodynamic cap attached. While the tank´s gun has a diameter of 120mm the dart is much smaller, about 20-40 mm in diameter (depending on model). This means it has to be hold in the barrel by sabot petals, which fall off after the projectile leaves the muzzle.
    You can see this here:

    All APFSDS rounds look like this:
    [​IMG]

    But as I said, this is just one ammo type. The problem with using it against "soft targets" is that you have to hit those directly, as the round completely relies on kinetic energy for destruction. The round might even pass through soft skin vehicles without causing much destruction as it relies on sending chunks of the target´s armor around in the inside as shrapnell to a certain extend. Also, the round has to meet resistance to develop the pyrophoric effect mentioned above.
    For this reason a second round is used, the M830 HEAT round. It uses a shaped charge which isn´t reliant on kinetic energy but is a chemical energy round which is triggered by an impact fuze. This round is more effective against light armored vehicles and troops, even though it doesn´t have the punch of a real HE-FRAG(mentation) round.
    For this reason again the M830A1 MPAT round was developed. It uses a saboted shell which features a shaped charge and a shrapnel mantlet around it, therefore increasing effectivness and generating a fragmentation pattern. This is the round that should be most common in iraq by now.

    As you see it doesn´t make sense to use DU at all in the current situation. DU ammo only makes sense if you face Armored Fighting Vehicles, which is not the case in iraq.

    am i right in the thinking that misinformation is the cause of conspiricy theorys? and that stuburness is the keeper of these theorys?
    you cant blame people for starting these theorys as it is based on misinformation, stuburness however is the real problem

    Ok, so now that everyone has said something in this thread, let separate out the facts please.

    Is this a real issue? Are these DU rounds really being used in Iraq? Is there ANY reason for me to worry about my boyfriend, who is going to be shipping out to Iraq in the next few months? What is the REAL story on this stuff?

    Like I said, DU isn´t used in any significant quantities these days (if at all).
    Ammo exists for the following weapon systems in theatre:
    -Abrams MBT: M829 series of APFSDS ammunition (explained above).
    -Bradley IFV: M919 series of 25mm APFSDS ammunition for the M242 Bushmaster gun.
    -A-10 Thunderbolt ground attack aircraft, PGU-14 30mm API ammunition for the GAU-8 gun.
    -AV-8B Harrier aircraft used by the marines. Pgu-20 25mm API ammunition.

    Strafing runs by aircraft are extremely unlikely in iraq these days, so you can rule this out. The usage of DU ammo by armored fighting vehicles also is unlikely as it only makes sense to use against armored vehicles which the opposition doesn´t have right now. To minimize the remaining risk your boyfriend might should refrain from climbing on shot up vehicles from earlier in the war.
    My advice is that he should look up as much info from people that were there as possible, IEDs and insurgents is what pose the real threat as opposed to DU. A good site would be http://lightfighter.net ,there you can find lots of tips on equipment, tactics and stuff.
