i thought it was more of an electric cherry smell. i could taste it as well slightly. like you said at the right heat and for me i noticed it more for certain steels and fresh steel. also when moving large volumes of material. i havent found any scientific reasoning for this yet in searching besides this forum.

yeah i think this is more of a concern than IR and UV. epa article: http://www.epa.gov/rpdweb00/tenorm/coalandcoalash.html oak ridge national labs article: http://web.ornl.gov/info/ornlreview/rev26-34/text/colmain.html wikipedia on fly ash: http://en.wikipedia.org/wiki/Fly_ash wikipedia on radiation and radiation exposure with sample equivalents to varied radiation doses: http://en.wikipedia.org/wiki/Millisievert wikipedia on radio active waste featuring coal as a primary constituent: http://en.wikipedia.org/wiki/Radioactive_waste
