Comment on Hiroshima scientists turn any smartphone into a radiation detector

This costs “less than $70”.

You can get a cheap Geiger counter for $50 today and it’s about the same size. I see some for $30-40. These are based on old, proven technology, not some new thing with new problems and an app.

Not that it isn’t neat, but it’s kind of a solved problem.

Well, technically the hair loss is permanent if you die afterwards.

Yes, but a cheap Geiger counter doesn’t use AI. Get with the times.

What’s LD50 and LD99?

  Other comment is wrong. LD50 = 50% chance of dying. LD99 = 99% chance of dying. The figures I listed are for humans, not mice. LD50 in mice is likely drastically different than LD50 in humans.

  We test on animals. Mice specifically, so we take the amount that killed the mouse and multiply by 50 to get an estimate on the Lethal Dose for humans. So i guess depending on the human the true lethal dose is going to be some where between 50 times the Lethal Dose and 99 times the Lethal Dose.
  
  So “LD” is the amount it took to kill a mouse and 50 times that or “LD50” is the estimated lethal dose for a human

    Incorrect. LD50 is lethal dose to kill on average 50% of the time. LD99 is the dose that kills 99% of people.
