"Dino-radiation?"

[Mack Richard <MRICHARD@WPO.IUPUI.EDU>]

Radsafers:

An article in a local newspaper had the following byline - "Homemade
device finds dinosaurs."  An excerpt from the article states "The
device, a wedding of high-tech and low-tech, can pinpoint faint
radiation emanating from a dinosaur fossil through stone up to a meter
thick."

There is a picture of the developer of the device (Ray Jones from Univ
of Utah) with an assistant using the device.  It looks kinda like a NaI
detector mounted in some type of frame.  Anyone out there ever heard of
this device, how it works, what radiation it is detecting, etc.?  My
interest is purely academic.
