I feel your comment isn’t very constructive and is a little demeaning.
Quit 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.
You 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?
This 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.
Uranium's danger isn't from its radioactivity when ingested either, its a toxic heavy metal much like lead.
Sure, 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).
The 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.
