A system to SEE ionizing radiation... interesting?

Here is an article on the Gamma Camera in use at Argonne National Laboratory (page 19).

Dear Marlin,

Many thanks! It seems very interesting. I will examine it very carefully.

Thanks another time!

A nice gamma cam (Radsearch from Antek) with a LaBr detector, a videocammera and a laser ranger. They use it to characterize some "hot places" before D&D tasks in ANL.



I wonder if this system is fast enough to allow a complete characterization of an entire cubicle in a reasonably time for normal D&D jobs. Also if cost is also reasonably. I have post a question on the NucDecReport article related...

We are just working in "robotization" the characterization surveys for D&D projects (a robot that goes and takes the measures), but if current gamma cams like this one may provide the information fast and in a cost-effective way... we may not be very successful!

I will be very grateful on any comment!!!!!

For a characterization survey; a gamma camera coupled with a Canberra ISOCS unit works well.
The gamma camera shows exactly where the holdup material is in the piping and other systems and the ISOCS gives gamma spectoscopy nuclide identification.

Doing the characterizations this way and covering flat surfaces with a 600cm2 beta probe allowed for some very ALARA D&D planning.

Flashing back to the River Corridor Project at Hanford at the turn of the 21st century.

Please check out the GammaCam: http://www.gammacamnow.com.   Over twenty of these systems were sold in 2011 and 2012 to companies in Japan in response to the incident at Fukushima.  The website has several white papers that review the system in actual applications in Nuclear Power Plants and Processing facilities.
