Their science is all bogus. A UV light does not show up radioactivity, but it can cause certain chemicals to become phosphorescent – they take in the UV light energy and emit this as visible light.
Phosphorescence – Wikipedia, the free encyclopedia
There is probably some kind of phosphorescent additive in the tobacco – but it may be relatively harmless, probably less so than smoking!
historically low level sources of radiation were used alongside radioluminescent chemicals to make things like watch dials and gun sights “glow in the dark”, hence the association of ionising radiation and green glowing stuff, but nowadays “glow in the dark” stuff is phosphorescent and simply recharges from the visible light of the sun. For instance I use a 340 test telephone for work with a “glow in the dark” dial, but it isn’t radioactive..
I also do have a UV LED pocket torch (there are lots of interesting phosphorescent items both man made and natural) but I gave up the gaspers some months ago so haven’t got any cigarettes to investigate.They are bad for you anyway, I am better off without them.
