Thing with alpha emitters is, if you get it on you the outer layers of skin will stop it before it does much damage. If you get it *in* you, where there's living tissue way closer to the surface like in your mouth or your lungs, it'll give you an absolute rip-roaring tumour.

- kennend3 4y agoMost adults stopped putting strange things in their mouths a long time ago. But agree, Alpha emitters are a problem if taken internally, which is why i stated breathing/drinking tritium increases cancer risks. there is not a clear line between "alpha exposure" and "rip-roarding tumour"... See "nuclear medicine", "radioactive tracers" etc for examples of where alpha emitters are intentionally given to patients.
- Gordonjcp 4y agoYes,-ish but look at the isotopes used for radiotracers in medicine - they typically undergo beta decay and their half-lives are in the order of minutes, mostly, with phosphorus having a half-life of about a fortnight and sulphur about three months.
