Powernet: Need MCA type device to be used in determining if items contain only NORM

[Barber, Jerry]

We are looking for recommendations on a device we should buy and have on hand 
to perform MCA/gamma analyses on items (e.g., vendor equipment) that alarms 
SAM, in order to determine if the activity is NORM or licensed material.   
Someone have an instrument that does a good job at this?
