[ RadSafe ] Fw: Certifying radiation "free" Japanese imports

The problem is that most handheld instruments are not sensitive enough to detect and identify extremely low levels of contamination. The levels required to be measured would determine what equipment would be needed - i.e., hand held Ge or NaI detectors or just gross counting ultra sensitive ones.

Could start with ANSI N42 Standards that and instruments that state they meet these requirements, as well as DHS and NIST documentation. I'm also copying Mike Unterweger, NIST Group Leader , Radioactivity Group and Chair, N42.
Hope this helps!

[aihaih-list] Certifying radiation "free" Japanese imports
It is not my usual practice to send one question to multiple lists, but in this case I need to seek information as broadly as possible. If you see this message more than once, please accept my apologies for the duplication.
Let me give you some background before I ask my question.
Because of the nuclear power plant problems in Fukushima, some countries are forbidding import of agricultural products from that area or Japan, or from all of Japan. In the US all imports from Japan are receiving increased radiological scrutiny.
In Japan, a regulation has been issued requiring that agricultural products be certified by the exporter as radiologically acceptable.
("acceptable" is my term.) It would seem that some countries are also requiring such certification from their Japanese suppliers before admitting products from Japan. What I can find on the internet about this is currently focused on agricultural products. However, there seems to be some thought that certification might expand (or perhaps has
expanded) to non-agricultural products. The Japanese government certifies certain radiation detection instruments for this purpose.
Now my question:
Does the US government (Ag Dept, NRC, Customs, other?) specify or certify radiation detection instruments for use in such certifications?
I have been asked by Japanese contacts which instruments are acceptable to the US Government. My initial thought is that the government agencies concerned would want an appropriate instrument to be selected and to have been calibrated within the appropriate time period, but do not certify or specify particular brands or models, and that, therefore, any instrument certified by the Japanese government and properly calibrated and used would be acceptable to the US..
Does anyone have concrete information or guidance in this area?
