Sorry, you are wrong here. I am a Pharm Chemist and have done RadioPharm work...external contamination is rare, and cleanable. Hell, my bangs got contaminated with P-32, and between cutting and cleaning I was ok.
A lot is made of the aluminum tube found in the garden of Saddam's chief nuke scientist. It is supposed to be the precision-machined aluminum tube used to make a centrifuge. Yet we know it takes thousands of centrifuges to produce enough material for a bomb in a five to ten year period, assuming enough electricity is available (live TVA in WW II). So, assuming that part is a prototype, where are all the rest of the machines? Where are the materials to be used to make them?
OK, for your info...let me give you an overview on UF-6 (Uranium Hexafluoride) and the importance of High Purity Aluminum tubes...allow me to bold certain passages...
_________________________________________________________
"Uranium hexafluoride, or UF6, is a compound used in the uranium enrichment process that produces fuel for nuclear reactors and nuclear weapons. It forms solid grey crystals at standard temperature and pressure (STP), is highly toxic, reacts violently with water and is corrosive to most metals. Higly pure refined Nickel is also impervious to UF-6
Milled uranium ore -- U3O8, or -- is dissolved in nitric acid, yielding a solution of uranyl nitrate UO2(NO3)2. Pure uranyl nitrate is obtained by solvent extraction, then treated with ammonia to produce ammonium diuranate (ADU). Reduction with hydrogen gives UO2, which is converted with hydrofluoric acid (HF) to UF4. Oxidation with fluorine finally yields UF6. It is used in both of the main uranium enrichment methods, gaseous diffusion and the gas centrifuge method, because it has a triple point at 64 °C (147 °F) and slightly higher than normal atmospheric pressure. Additionally, fluorine has only a single stable naturally occurring isotope, so isotopes of UF6 differ in their molecular weight based solely on the uranium isotope present.
Gaseous diffusion requires ca. 60 times as much energy as the gas centrifuge process; even so, this is just 4% of the energy that can be produced by the resulting enriched uranium."

So,you see, the Lamestream mediots and the DemonRAT talking points that the Aluminum tubes were for missiles is crap! High Purity Aluminum is weak in tensile strength...not something one wants in a missile housing! Which is why those parst are made from alloys...not the most expensive, highly refined Pure Aluminum! The Aluminum in Centrifuge tubes needs to be as pure as possible, because the UF-6 will eat any impurity!
Saddam's folks welded fins on the tubes so weak-minded fools could say "Nope, nothing here"!
Seriously, unless you've been in the industry, you do NOT know what you are talking about.
As far as "where are all the other materials/parts"...allow me to aquiant you with the Bekka Valley in Syria...soon to be the Bekka Plains.
Also look to other Islamazi Nations that support the Koranimals...oh, and don't forget the 3 "Mysterious" Freighters that were roaming around right before and just after the Iraq Invasion!
