Which metal is used for containers that store radioactive sources? Answer in words not symbols. Abeeb olasupo (talk) 19:57, 7 March 2023 (UTC)[reply]

Lead storage containers can be used to store and transport radioactive material. The standard outside and inside finishing is coated lead so there is no exposure to the lead by personnel. A stainless steel finishing is also available to provide a stronger housing. Rawsar6 (talk) 22:17, 26 January 2024 (UTC)[reply]

I do not agree that this reference should be cited in the article. The primary reference is the United States (US) Food and Drug Administration’s (FDA) Total Diet Study (TDS) for fiscal years 2018 through 2020. The report does not make any alarming claims about the results. Since this is about health and safety, only a professional analysis of this report would be adequate as a source. dailymail.co.uk does not qualify for that purpose.

And also unreliable, per WP:USERGENERATED. If you want to worry about radiation, I suggest you focus on radon, well documented as the 2nd leading cause of lung cancer, much, much more common, and a gas that can be inhaled. Johnjbarton (talk) 02:03, 17 September 2024 (UTC)[reply]

"...and poses significant health threat and environmental impact." should be "...and poses a significant health threat..." or "...and poses significant health threats..." — Preceding unsigned comment added by YSWEISS (talk • contribs) 15:52, 25 June 2023 (UTC)[reply]

"...The development and deployment of these nuclear reactors continue on a global base as they are powerful sources of CO2-free energy." Should be "The development and deployment of these nuclear reactors continue on a global base as they are powerful sources energy." The fuel cycle of nuclear plants is not CO2-free. Mining, enrichment, and disposal are high CO2 pollutants. Only the operating part of the cycle is free of CO2 emissions. — Preceding unsigned comment added by 2601:1C0:6701:C850:DF0C:A1ED:F89C:E4BC (talk) 21:48, 10 September 2023 (UTC)[reply]

In the article "Isotopes of uranium", i edited out an astonishing amount of unnecessary verbiage, particularly from the section "Uranium-234". Okay? Solomonfromfinland (talk) 05:54, 29 March 2024 (UTC)[reply]

Our article says

• In 1943 the Manhattan Project arranged for a worldwide listing of Uranium and Thorium resources.

citing

• Groves, L. M. (2024). Now it can be told: The story of the Manhattan Project. Hachette+ ORM.

which I don't have access to. I suspect that this curious sentence really means:

• In 1943 the Manhattan Project attempted to list every source of Uranium and Thorium throughout the world.

Surely the "arranged" here does not mean "call on a listing service" or "asked for bidders to create a list" or whatever. This was a top secret project so "arranged" is entirely in house. Johnjbarton (talk) 02:37, 21 October 2025 (UTC)[reply]

Thanks! Fixed it.  Done Johnjbarton (talk) 16:08, 21 October 2025 (UTC)[reply]

Under the "Human Exposure" heading, the second paragraph has a typo. Where it says "The health impacts of natural and of deleted uranium", "deleted" should be replaced with "depleted" Ethan Grigsby (talk) 22:18, 12 January 2026 (UTC)[reply]
