[ RadSafe ] Radiation survey of Japanese automobiles after Fukushima

In the weeks after the F-D event I surveyed contaminated sea-land containers that originated from ports in Japan.  The activity of alarm events from the Port's portal monitoring decayed out (pun intended).  Once in a while we get notification of a hit on a truck exiting the Port, but have not seen activity in months.  A gamma-spec of some of the initial containers indicated Cs-137, Cs-134 and lesser ratios of I-131.  The contamination almost always was the result of environmental (removable) contamination in cracks and crevices of the container exteriors.

Subject: [ RadSafe ] Radiation survey of Japanese automobiles after Fukushima

I am wondering if anyone else has been asked to perform radiation survey on automobiles from Japan in relation to the Fukushima-Daiichi event?  I have heard of a few people who were approached by car dealerships to perform radiation survey a few years ago (and find nothing) and I was recently asked the same.  I would like to find out of this phenomena is widespread and continuing. Also, if anyone knows of anything published to this effect, I would be interested in reading about it.
