I'm looking particularly at KI and the chelating agents, which are ordinary shelf-stable things. The point of these is to prevent biological absorption of particular elements in fallout, so either you have them available right away, or it's a lost opportunity.
- "Time of treatment initiation: DTPA should be administered as soon as possible after exposure, ideally within the first 24h. If early administration is not possible, therapy can be initiated at any time; however, the efficacy decreases substantially when radionuclides are deposited in the bone and other organs (47, 48)."
- "The optimal period of administration of stable iodine is < 24 h before and ≤ 2 h after the expected onset of exposure."
- adrian_b 4y agoK iodide (KI) is not completely shelf stable, it oxidizes slowly in air (into elemental iodine, which is unsuitable to be ingested as a iodine source for humans). K iodate (KIO3) is completely shelf stable, but it can be unpleasant when taken in very large doses.
- erdewit 4y agoElemental iodine in solution with iodide forms tri-iodide, which is perfectly fine to consume. This is what Lugol's solution is and it has an unlimited shelf life.
- adrian_b 4y agoIt is fine to consume, but the part of the iodide that has been converted into iodine can no longer be transformed into a useful form inside the human body. Therefore any reserve of iodide will provide a smaller dose than expected when it is too old, unless it was stored in special conditions, e.g. in nitrogen without contact with air.
