Lead has an infinite half-life, since it's not radioactive. How much would you be willing to accept in your water?

- MapleWalnut 7y agoI feel your comment isn’t very constructive and is a little demeaning.
- lightedman 7y agoQuit reading their words in your internal voice. You're the one attributing emotion to a statement with no emotionally-charged words. We even had that story here on HN and yet nobody seems to have learned from it.
- mark-r 7y agoYou assume that radioactivity is the only danger emanating from Uranium in the water. I was merely pointing out that it is not the only thing to be worried about. Elements can be poisonous without being radioactive. Was that a little more constructive?
- manfredo 7y agoThis is nonsensical. Lead's danger isn't from its radioactive decay, though. It's from its chemical properties that make it harmful to the nervous system.
- throwaway2048 7y agoUranium's danger isn't from its radioactivity when ingested either, its a toxic heavy metal much like lead.
- manfredo 7y agoSure, but why are you referring to half life if you're talking about toxicity other than radiation? Half lives are irrelevant to chemical toxicity (at least, not unless something decays into something with different chemical properties).
- EdwardDiego 7y agoThe commenter you're replying to made no mention of half-life. The commenter who did make mention of half-life with regard to lead, was doing so to show that framing the uranium issue solely as a radiation issue was misguided, at best.
