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/ 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.
