Nerf Prussian blue, add other chelators #46190

Is your feature request related to a problem? Please describe.

Comments made in the course of resolving PR #46181 led myself and @actual-nh to a discussion on the role of Prussian blue; specifically, Prussian blue can chelate and sequester certain heavy metals, but it isn't radioactivity-specific. This is in contrast to its presentation in Cataclysm.

Describe the solution you'd like

Consider slightly reducing Prussian blue's effectiveness, as well as adding certain other chelators to the game to fill the gap.

Describe alternatives you've considered

No alternatives considered at this time.

Additional context

Strontium-90, which Prussian blue can also sequester according to some data, is both used in RTGs (which appear to be rather more common in the Cataclysm world) and a major concern in nuclear weapon fallout. Adding some other chelators to the game, and limiting Prussian blue to some fraction of radiation absorbed, may be a good idea in the long run. (I am assuming the various healing-related changes in the post-Cataclysm world are helping recover from radioactivity - it's instead promoting mutations!) I need to work on dialysis tubing - you would definitely want to replace it in a dialysis machine if you were using it to help extract chelated radioactive heavy metals! Chelation is hard on the kidneys...

I am specifically thinking of dialysis because the usual way to avoid problems is administering it slowly (over days or weeks). If a survivor gets a heavy dose of radioactive material, they're not going to be able to do that for various practical reasons (e.g., the side effects of the - often toxic themselves - radioactive metals would be too disabling if they happened for any lengthy period of time). Dialysis is also specifically used to treat exposure to uranium - see this link for that and some other information (including on possible treatments not approved by the FDA, despite this being a governmental site).

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions. Please do not \'bump\' or comment on this issue unless you are actively working on it. Stale issues, and stale issues that are closed are still considered.

Will try to work on after semester is over - anything involving extended in-game testing takes me forever currently.

What exactly does the character's radiation value mean: absorbed does of radiation or amount of radioactive material in their body? If the earlier, should prussian blue work at all?.. If it's mixed up now, should this be rather fixed first? Or am I getting radioactivity entirely wrong?
