I guess it all depends on your definition of a "hot particle". This could just mean that something above background was detected. We define a hot particle as a radioactive particle with a contact dose rate of >100 mrem/h. I can't imagine any hot particles, NORM, or TENORM in the public domain of Washington having dose rates of that magnitude?

Subject: [ RadSafe ] Hot particles on automobile air filters
I have received several calls and emails from people in Washington who
are alarmed about "hot particles" being found on automobile air filters.
The only source I found for this is a vague statement from Arnold
Gundersen in an article he gave to Aljazeera. I admit that I do not
give to this source the same credence I would give to an article in a
peer reviewed journal.
Has anyone seen anything else about this?
