This was posted on HN recently.... Tobacco smoke contains Polonium-210, the same stuff used to murder the Russian spy Litvinenko. A pack and half a day exposes the smoker to the same amount of radiation as 300 chest xrays a year. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2509609/

So someone just needs to blow some vape on a Geiger counter to test its radiation levels. I suspect the vape will be radiation free, as it doesn't need to contain the extra chemicals that lend tobacco its flavour.

Wtf, radionuclides aren't flavorings they're concentrated from soil by plants!
