RE: Portable gamma spectroscopy
Richard:
Consider the Exploranium radiation detection systems, specifically their 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.

One of these days I'll learn how to phrase a question that doesn't raise
more questions than answers. Which is not to say that I haven't gotten some
good answers already. However, several people have questioned what we are
trying to do. So...
Like many organizations post-9/11, we're reviewing our security
arrangements. In this case, we're looking into what to do after an entry
gate or portal monitor alarms, alerting us to a radioactive source coming in
on a vehicle, in a package or on an person. One possibility under
investigation is to equip the security personnel with some device that gives
them a limited capability to identify the nuclides involve which they could
compare to a list of common medical and industrial isotopes. This would give
them the ability to "clear" some alarms without activating the entire
anti-terrorism response...whatever that is.
The group that is looking into this asked me for some advice in finding an
instrument that would allow them to do this. As I have no experience with
the kinds of portable systems that they would find useful, I thought I would
try to augment my ability to weed through manufacturer literature and
presentations with some personal experience of others. Thus my question to
Radsafe
I believe that the key factors will turn out to be: ease of use by security
staff, portability and cost. The ability to quantify activity, detect low
levels in a short period of time, or differentiate uncommon nuclides are not
required and may not be desirable. Certainly any system that requires a
trained spectroscopist or substantial outlay of time and money to maintain
in the field will be excluded.
Thanks to everyone who has already replied.
