If people are checking their automobile air filters for radioactivity, it's very likely they would find it in the form of radon progeny.  I haven't heard of or seen anything else recently.

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?
