[ RadSafe ] Hot particles on automobile air filters

[Clayton J Bradt]

Chris Busby states:

"But these filters have been across the Pacific and in the mail system for 
a long time. 
The gamma spectrum of the filters shows Cs137 and I131." 

Now I'm curious.  Are these air filters replacement parts manufactured in 
Japan within the past 3 months and shipped to the US? 
If so, and assuming for the sake of argument that there are hot particles 
in the air filters, they would likely have been introduced during 
the manufacturing process - not during use.

Further questions: Have hot particles been found through the environmental 
monitoring in Japan?  Where is the manufacturing plant for the filters in 
relation to Fukushima? Has monitoring been performed at the manufacturing 
plant?
