Rules for Posting Guides on Our Community

1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.

2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.

3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.

4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.

5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.

6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

Community Guidelines

Direct Image Links Only Only direct links to .png, .jpg, and .jpeg image formats are permitted.
Educational Infographics Only Infographics must aim to educate and inform with structured content. Purely narrative or non-informative infographics may be removed.
Serious Guides Only Nonserious or comedy-based guides will be removed.
No Harmful Content Guides promoting dangerous or harmful activities/materials will be removed. This includes content intended to cause harm to others.

By following these rules, we can maintain a diverse and informative community. If you have any questions or concerns, feel free to reach out to the moderators. Thank you for contributing responsibly!

I can ingest nearly 10g of uranium and not die?

Interesting.

Depends on the isotope, of course. There are different ways it can hurt you.

If you put together a critical mass of ²³⁵U, it undergoes fission and you die in seconds without needing to ingest it.
Naturally ocurring uranium (²³³U-²³⁸U, mostly ²³⁸U) has a half-life of billions of years, so it's very weakly radioactive. It would take a lot of it to harm you from decay radiation. Or very little if you pick a very unstable synthetic isotope outside the 233-238 range (but every element "has" such radioactive isotopes, though not in nature).
Uranium is chemically toxic, which is whal will kill you if you ingest a small amount of a common isotope.

I think they are referring to Uranium with natural isotopic abundance. Which is complete bullshit when you put a picture of a nuclear power plant behind it – which in most cases can not function with the natural isotopic abundance (heavy water reactors being the exception, not the rule).
