| == Radiological weapon? == | |||
| 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'. | |||

| :: Well, as DU creates vast contamination areas on battlefields, there is no way to deny that this aspect actually does exist. However, this is not an effect intended by the military. At least they claim not to intend such effects. Nevertheless it might be seen as a criminal act to cause such contamination as an unintended, but predictable and well known effect of DU use. So this is a rather tricky issue. ] (]) 19:48, 29 March 2023 (UTC) | |||
| == incorporated DU will directly harm body cell DNA == | |||
| In relation to other parts of this article, experts may wish to refer to , advertising/advocating for uses of DUF<sub>6</sub>. | |||
| There should be at least some explanation in the text concerning DU dusts entering body cells when inhaled. This causes radioactive radiation to be created directly in body cells, obviously causing direct harm to cellular DNA, thus probably causing cancer and various birth defects. So far, there is no such aspect mentioned in the article... ?! ] (]) 19:53, 29 March 2023 (UTC) | |||
| 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.) | |||

| :Depleted uranium is notable for the extremely high density of its metallic form: at 19.1 grams per cubic centimetre (0.69 lb/cu in), DU is 68.4% denser than lead. | |||
| This is misleading; depleted uranium has the same density as natural ]. It's just that its lower radioactivity makes it useful in applications where the radioactivity of natural uranium would be a problem. | |||

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)
- There was a Sydney headline "A Baron of beef" at the time but I can't find it in Trove. Andrewa (talk) 21:57, 29 July 2022 (UTC)
Radiological weapon?
Can be the DU ammo be categorized as a radiological weapon? Though not used as an area-denial material, the DU has the secondary effect of contaminating the targets it hit (tanks, armoured vehicles, bunkers, etc.). The US vehicles struck by friendly DU rounds in both the Gulf War and the Invasion of Iraq had to be "washed" as they represented some radiological hazard.----Darius (talk) 00:58, 14 November 2020 (UTC)
- That doesn't make it a radiological weapon, which are nuclear weapons or dirty bombs used for area denial, . VQuakr (talk) 17:39, 16 November 2020 (UTC)
- Well, as DU creates vast contamination areas on battlefields, there is no way to deny that this aspect actually does exist. However, this is not an effect intended by the military. At least they claim not to intend such effects. Nevertheless it might be seen as a criminal act to cause such contamination as an unintended, but predictable and well known effect of DU use. So this is a rather tricky issue. 88.67.87.171 (talk) 19:48, 29 March 2023 (UTC)
incorporated DU will directly harm body cell DNA
There should be at least some explanation in the text concerning DU dusts entering body cells when inhaled. This causes radioactive radiation to be created directly in body cells, obviously causing direct harm to cellular DNA, thus probably causing cancer and various birth defects. So far, there is no such aspect mentioned in the article... ?! 88.67.87.171 (talk) 19:53, 29 March 2023 (UTC)
Density of depleted uranium
The article currently says:
- Depleted uranium is notable for the extremely high density of its metallic form: at 19.1 grams per cubic centimetre (0.69 lb/cu in), DU is 68.4% denser than lead.

This section should be modified to make that clear. TypoBoy (talk) 18:53, 12 April 2024 (UTC)
