Re: Portable gamma spectroscopy
They are also sold by Ludlum Measurements here in the USA.

miniSPEC. We have one and found it quite useful in field situations. I
know they have a nuclear medicine library module that recognizes the common
nuclear medicine nuclides. They are in Ontario Canada and the phone is
905-670-7071. Judging from your described needs, I would bet this is would
fit the bill. They are light weight, easy to field calibrate, and the info
downloads to your computer for better analysis.
