      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.

      Wow i am massivly wrong. A simple wiki search would have set me straight. Sorry all, dont listen to me. (Below is original comment, ill wear my shame on my sleeve)

      ~~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~~

        Your entire comment is incorrect. LD50 is lethal dose to kill on average 50% of the time. LD99 is the dose that kills 99% of people. The figures I listed are for humans. There’s no way to extrapolate LD50 from other species to humans. There is enough data on humans radiation exposure to directly calculate LD50.
