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

Thu Apr 21 12:56:49 CDT 2011

The device mentioned by Sandy is designed to determine surface contamination, is 
it not?  

Isn't the concern regarding foodstuffs from Japan being embargoed primarily a 
concern with radioactivity taken up by foods, and at a minimum requiring 
sensitive gamma isotopic analysis of a food sample to get a decent lower limit 
of detection with acceptable precision for specific isotopes in  Bq/kg that 
would correspond to some established dose limit??  

We can still routinely measure preexisting nuclear bomb test fallout from open 
air testing [primarily Cs-137 by gamma,, or Sr-90 with radiochemistry and 
low-level beta counting ] in environmental media of many types - fish, 
vegetation/crops, milk, and others.  So any measurement must be able to document 
if it exceeds what is now, in effect, background levels of fission related 
isotopes everywhere in the Northern hemisphere.

Am I missing something?

Not going to do a long commercial but here is a device sold by the Health 
Physics Division, Mirion Technologies, that has been acquired by many US and 
Japanese entities recently. RDS-80 handheld surface contamination detector

Here is a more sophisticated unit, measures <0.4 Bq over 100 cm2

Hope this also helps.

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?

Thanks.
