| == Edit on shaped charge warheads and uranium == | |||
| }} | |||
| Here are the changes I want to bring on the "Ammunition" section re. shaped charges and uranium : | |||
| It is known since the years 70s that uranium can be used as a liner in shaped charge warheads<ref>{{cite book|title=Trends in the use of depleted uranium|date=1971|publisher=National Academy of Science|pages=38|url=https://books.google.fr/books?id=qJArAAAAYAAJ&pg=PA38&lpg=PA38&dq=shaped+charge+liner+uranium&source=bl&ots=y1QG-EIyHf&sig=GE4XeIc25mhKH6mv2bR-6ycn6S8&hl=fr&sa=X&ved=0ahUKEwilnvnGvejSAhXLhRoKHeR2CSEQ6AEIczAQ#v=onepage&q=shaped%20charge%20liner%20uranium&f=false}}</ref><ref>{{cite journal|title=Building characteristics into a shaped charge to achieve unique performance requirements|journal=International Journal of Impact Engineering|date=1995|volume=17|issue=1-3|pages=121-130|url=http://www.sciencedirect.com/science/article/pii/0734743X9599841E|accessdate=21 March 2017}}</ref>. Many shaped charge warheads patents include uranium as a liner. The "K-charge" patent EP 1164348 A2 notes that "other metals that have been disclosed as useful for shaped charge liners include depleted uranium and their alloys<ref>{{cite web|title=K charge patent|url=https://www.google.com/patents/EP1164348A2?cl=en&hl=fr|website=Google patents}}</ref>". Another seems to acknowledge that it is better, for incendiary (reactive) purposes, to use non-depleted uranium as it differenciates "depleted uranium" used for kinetic purposes and "uranium" used for incendiary purposes. | |||
| Please tell me where does that violate any Misplaced Pages policy. Thanks. ] (]) 22:09, 21 March 2017 (UTC) | |||
| :Claiming that a specific warhead must contain uranium because a patent application says uranium ''could'' be used violates common sense, ], and ]. Claiming natural uranium is more flammable/pyrophoric than DU based on a patent application indicates a pretty remarkable lack of knowledge of chemistry, and of course also violates the same content policies. ] (]) 22:16, 21 March 2017 (UTC) | |||
| ::It does not says that uranium IS used in liners, it only says it COULD. It was thoroughly studied ( see for instance here http://www.arl.army.mil/arlreports/2007/ARL-SR-150.pdf on page 86). Jane's also reported once that uranium is used in "some guided weapons" which could include shaped charge warheads. https://web.archive.org/web/20011108102307/http://www.janes.com/defence/news/jdw/jdw010108_1_n.shtml | |||
| ::Regarding the effects of radioactivity on inflammability (the latent heat of the radioactivity acting as the activation energy), two chemists (one in a metallurgy lab, and one "agrégé" (French high exam for professors)) have told me that I am right, so I thought that simply making mention of the patent without explaining could be meaningful, but I acknowledge this contradicts WP:SYNTH.] (]) 22:45, 21 March 2017 (UTC) | |||
| ::: "which could" | |||
| ::: ] (]) 23:23, 21 March 2017 (UTC) | |||
| :::: If you read the uranium liner shaped charge patent for drilling wells https://www.google.ch/patents/US4441428, you'll see that "tests show that the penetration of such a Uranium jet is about 87 centimeters, a factor of 3.5 greater than expected and a factor of 5 times that measured for the copper jet and for an iron jet 5.4 times greater." In this regard claims that the main metal used in shaped charges is copper is highly dubious. ] (]) 20:43, 24 March 2017 (UTC) | |||
| ::::: Re these weapons I actually claim, based on personal work and on a testimony, they use nano levels of nuclear fission. U236 all around Iraq and Afghanistan (UMRC work), the micro flashs you see when these weapons explode (bunker busters, anti tank missiles, cruise missiles etc), tritium I have found in high volumes near Canjuers military camp in southern France and beryllium consistently used in uranium weapons (see Observatoire des Armements report, October 2001 "La production des armes à uranium appauvri") do confirm that. A former tank driver from the French army confirmed all that. Won't insert it in the encyclopedia because personal research.--] (]) 19:30, 5 September 2017 (UTC) | |||

| == Edit on missiles and bombs and uranium == | |||
| Hello, | |||
| I would like also to suggest an edit including the following elements : | |||
| - It has been demonstrated that the Baghdad Al Amariyah bunker destroyed in 1991 by two GBU 27s (killing more than 400 civilians that had taken shelter there, in a fire) was still radioactive in 2002 (see https://www.youtube.com/watch?v=IsX41A8JiBw&feature=youtu.be&t=8m47s video] from movie Irak, d'une guerre à l'autre, on ). | |||
| - There are reports that uranium is being used as a counter-ballast in missiles - for instance, this on the Balkans, in the annex. The "Depleted Uranium Hazard Awareness" training video for the US military that Doug Rokke had to make also included the mention of the use of uranium in missile ballasts (see ). | |||
| - The BBC also reported that GBU bunker buster are believed to contain depleted uranium (see ). | |||
| To me the detection of peaks of uranium in Aldermaston air filters (see https://pyrophor.files.wordpress.com/2016/06/aldermaston.png?w=768), that rise when battles are waged in Afghanistan / Iraq, also is a good demonstration of the use of uranium in missiles and bombs : take the Anaconda Op in Afghanistan, tanks weren't involved so no possibility that the uranium detected in the filters comes from APFSDS shells, and it is very unlikely that dust from 30 mm straffing rounds would be able to rise at several kilometers of altitude and travel across the world. Compare with clouds of dust from missiles / GBU bombs. | |||
| Best regards,--] (]) 19:25, 25 March 2017 (UTC) | |||
| :: That's the film with ] as a talking head, right? Seems about par for your usual credulous standards on sourcing. Your clip begins by someone using a hand-held counter / dosimeter to measure alpha radiation. If you ever meet a real health physicist, ask them to explain why that's nonsense. | |||
| :: Also you seem confused over the first interim GBU-27s used in the Gulf (a seeker head on a recycled 8" steel gun tube), compared to the production versions with the DU penetrator. ] (]) 20:36, 25 March 2017 (UTC) | |||
| ::: 1) Please I need the source regarding GBU with DU penetrator, could you provide it if you have ? Thanks Andy ! | |||
| ::: 2) Geiger counters have been very frequently used to monitor uranium contamination because of the 49 KeV gamma rays of 238U. The CRIIRAD for instance recommends their use for that purpose even though there are differences whether you select HP0.07 or HP10. ] (]) 14:52, 26 March 2017 (UTC) | |||
| :::: Gamma from DU? Please, if you're trying to find "the hot spot in the room" from a small piece of hot material, then you might use a gamma counter based on a windowless or shielded G-M tube. But for a site survey of a site that's not heavily contaminated (and this is far from a heavily contaminated site, whoever you ask), then waving such a counter around at waist height isn't the way to go about it. It's a Kim & Aggie job, vacuuming up dust and bagging it. ] (]) 15:03, 26 March 2017 (UTC) | |||
| :::::Well of course alpha spectrometry is better but much costlier. CRIIRAD, though, recommends some Geigers for DU detection (there is also the beta minus of daughter products 234Th and 234Pa that can be detected by these Geigers), at least for a general survey of the contamination landscape. Would you please send me the source regarding DU penetrators in production versions of GBU 27 ? Thanks !!! ] (]) 16:38, 26 March 2017 (UTC) | |||
| It would also make a lot of sense to include the , for WDU clearly is an acronym for Warhead Depleted Uranium (Parsch reports it is "explosive", not "dummy" as mistated elsewhere). ] (]) 16:44, 11 May 2017 (UTC) | |||
| :Please provide a reliable source that explicitly states that all warheads with a WDU designator contain depleted uranium. That is an ] claim. ] (]) 19:28, 11 May 2017 (UTC) | |||

| == Studies indicating negligible effects == | |||
| It is somewhat concerning that most of the quoted studies appear to be from sources that - to put this politely - have a direct interest in the outcome of their work. That is, the quoted entities are: | |||
| # A literature review by Rand Corporation | |||
| #An editorial paper (i.e. not a study) in the Archive of Oncology (this in turn states that " a considerable part of the research work presented here has been sponsored by local government authorities.") It also appears from the editorial that the entire edition of that publication was to discuss this concern - but unfortunatley the rest of the edition is not available at that link. | |||
| #A study "from the Australian defense ministry". | |||
| #The ] (no study, just a statement). | |||
| #A study by ], which in turn is "a wholly owned subsidiary of Honeywell International" and "is one of three ] research and development laboratories". | |||
| Rand Corporation, the Australian Defence Ministry, and Sandia are all reliant on the largesse of governments that support the use of depleted uranium and thus non-neutral parties. The Archive of Oncology seems to be a more promising source, but the provided link is not to anything evidentiary. Similarly, the IAEA makes a statement rather than a study (and in some eyes may be considered less than entirely neutral). | |||
| To summarise, I suggest that either better sources are found or that appropriate caveats are added to this section of the article. The title does not reflect the current usefulness of the content, but I am sure that subject matter experts will be able to find some more reliable sources. Perhaps those used in the final sentence of the article's introduction might be a useful start - especially as they contradict the tone of this section. A brief survey also finds , though I am sure experts will have much more useful information to add. I realise that care must be taken in this area, as there are clearly many extremely interesting opinions 'out there'. | |||
| In relation to other parts of this article, experts may wish to refer to , advertising/advocating for uses of DUF<sub>6</sub>. | |||
| == Yacht keels == | |||
| Finally, in writing this comment I stumbled upon something about depleted uranium having been used in the past in dentistry. touches on its use, while provides some additional information on its history and advises against its use. Could someone who has some expertise in this area possibly add some dentistry to the history? (It is briefly mentioned in section 3.2 of the article, but if it has been discontinued then perhaps this should be moved - and I suggest expanded.) | |||

Yacht keels
At least one of the French 12 metre yachts that were built as America's Cup challengers used a DU keel, possibly France 3. I'm looking for references, any help appreciated. Andrewa (talk) 17:27, 25 September 2020 (UTC)
From memory it was one of the yachts financed by Marcel Bich, which means in 1970, 1974, 1977 or 1980, so it wasn't France 3 which was a 1983 effort. Andrewa (talk) 17:35, 25 September 2020 (UTC)
- I'm now less confident that it wasn't France 3. There was involvement by a Baron Bic or Baron Bich involved in that one too. Andrewa (talk) 20:55, 29 July 2022 (UTC)

I think we need something far more solid to show that it is a desirable feature, as I see no mention of it vs. Pb, the benefits I saw mentioned are pragmatic relating to the properties of the resulting instruments in detecting scintillations. Of course what I have read has only scratched the surface, so the text may well be correct. All the best: Rich Farmbrough 13:34, 9 November 2024 (UTC).
