burning coal makes a stove pipe radioactive ...
fellow i know has a stove pipe laying in the woods
extended family used it on a coal stove for over 60 years
has not been used for 30 years and it is still too radioactive to take to the scrap
yard so they coated it in tar and left it
i do not go where they are hauling CRUDE OIL near where i live some of it is hot
right out of the ground less than 20 miles northwest of my location
and the front 4 feet of my sidewalk has stone and gravel in it that's good to test a Geiger counter
with to see if it works
