Help in finding a specific Japanese CZT detector

[Nuclear_Ben_079]

Hello, i am wondering if anyone could help me find the name of this specific Japanese pocket CZT, made to test food products and other things for Cesium-137 contamination. It was created and used around Fukushima and this is sadly the best picture i have of the detector.

Here it is being used in a supermarket to check food for contamination after Fukushima at (2:33): https://www.youtube.com/watch?v=LUyUqoM ... w&index=17

I was able to find the name of the detector with the help of a friend.

It is called the TA100 Mini Spectrum meter, it comes with a 10mm x 10mm x 1mm CdTe and has a resolution of 3%. It also comes with a limited library of nuclides that it can identify.

I provided some product specifications below in English and Japanese (Google Translate the Japanese version for the full specification sheet)

PS: (Please do contact me if you possess one of these devices, as i would be interested in learning more about it)

Well identified, Ben. Not one I've seen before.

Looks like an interesting device, although with a crystal that's only 10x10x1mm, I imagine it's quite insensitive. We have some Kromek GR1s that have 10x the volume of CZT (1x1x1cm), and struggle with their efficiency, particularly for higher energies - so with a much thinner crystal, I imagine it's even worse.


I also had a peek at the video linked, and it's quite a showcase of lots of different detectors!

and then there's the chap at the end with his Eberline RM-19 and a 2" NaI setup who looks like he probably fit in well on this forum ;)

Yes, I have noticed those devices, my personal favorite being the Atomtex device as I am a big fan of their products, as well as Ecotest and Polimaster :). Btw, the chap with the eberline setup had his own Facebook, which was about finding contamination from the Fukushima disaster, though I was never able to find it sadly.
