Re[2]: mantle
Sorry Charlie, I disagree. In the past, Coleman's mantels contained Th, and
when a person talked about mantels you assumed they were radioactive. Coleman
discontinued using Th several years ago. However, mantles produced in some
foreign countries, and available in this country, still contain Th. So today,
at least to me, the term 'radioactive mantels' is synonymous with Th containing
mantels, whereas 'mantels' can refer to either radioactive or non-radioactive
mantels, or pehraps simply to non-radioactive mantels.

Thorium impregnated lantern mantles are not uncommon, so it is not clear how
much interest your post might generate. However, in the interest of
communication, you should be more specific. RADSAFERs generally know that
everything is, to some extent, radioactive. Consequently, saying "radioactive
mantle" means no more than saying "mantle."
