Hi Zoe, all...
Too, though I do not remember the specific characters
implicated to be afoot...
There is Radiation emitted from about any combustion...
...if one puff a Cigarette with it's end near a Geiger
Counter's senser, the 'ticks' and or the Dial shall leap...
Similarly, a Fire for Cooking or warmth or as may be...one
gets a good deal of 'ticks'...( if memory serve, a good deal
more than one should find poking it at a plate or saucer of
the old 'Fiesta Ware'...)

From talks with the health physicists, the combustion is letting loose
trace elements that were in the ground, both of the "natural" kind from the
soil and again from that dreaded results of burning coal which deposits
superfines into the atomosphere, which includes stuff those ancient plants
picked up from the soil (in concentrated form), and any uranics that were
precipitated out by geo-fluids percolating through the coal. Coal burning
is nasty stuff. The whole point is we need to evaluate risk.
