With some trepidation I respond: "radioactive" is one of those words
that are difficult to accurately define; however the laws of physics
(sorry Michael B) state that all objects having temperatures above
absolute zero emit radiation at all wavelengths in the electromagnetic
spectrum. This is something that we teach in remote sensing 101 and
could be used to state that all meteorites are radioactive.
As one of the characters in Buckaroo Bonsai said at the end of the
movie:
"so what, big deal".

With some trepidation I respond:  "radioactive" is one of those words
that are difficult to accurately define; however the laws of physics (sorry
Michael B) state that all objects having temperatures above absolute zero
emit radiation at all wavelengths in the electromagnetic spectrum.

Hello members,
I spent this last weekend
at a small local mineral show, selling a few meteorites, and answering
a lot of questions.
A gentleman came and told
me this:
 He is a teacher and took
his family to Meteor Crater last summer. There were quite a few visitors,
and someone asked the guide on duty:  " Are meteorites radioactive?" 
The guide answered without hesitation: " Yes, most of them are." Then someone
else asked "How about the meteorites in the gift shop?"  Again he
answered "Most of those are radioactive too."
 This surprised him so he
wanted to verify and asked me, and I did my best to explain that No! They
are not radioactive!   I think I convinced him.
Now, I was wondering if some
List-members who live in that area (Steve Schoner or Dave Andrews for instance)
would be willing to go check this out. And maybe teach that guide a few
meteoritical things.
No wonder the public is so
misinformed!!!!!
