Differential Gamma Ray Spectrometer
Accession Number: 2019.ph.848
A brown case with a rectangular footprint contains an orange-coloured metal instrument in a brown leather holder. The case has two latches and a brown plastic handle on the front case. On either side of the case is a foam liner with recesses for holding various components. The words “Jetliner” is moulded into the handle’s metal hinge.
The instrument’s holder has a cut out window through which the instrument’s display can be read. Two metal rings at either side may be used to attached a narrow shoulder strap, which is also included inside the case.
The instrument has a carrying handle and two knobs at the top surface, as well as cavity containing a source. The bottom has a cavity for holding “c” cell batteries, which is empty.
Also in the case is an orange painted metal mounting bracket and a key for locking the case.
Alternative Name: Scintillometer; minispec; UG135
Primary Materials: Plastic, Metal
A label on the front face of the instrument indicates that the model number is “UG135”.
A serial number engraved into the top surface of the instrument reads “SN90112”.
(Box) Height = 15, Width = 20, Length = 45.
A gamma ray spectrometer measures the spectrum and intensity of gamma radiation.
Excellent: This instrument appears to have been very lightly used. One edge of the the interior liner in the case lid appears to be separating.
Manufacturer: Urtec Limited, Uxbridge, Ontario.
Date of Manufacture: c. 1980s.
This instrument was among a set that was acquired for a teaching experiment in the University of Toronto Department of Physics Geophysics teaching lab. The experiment was called “Gamma-Ray Detection Using a Scintillometer.”
This instrument was gather by the UTSIC curator Erich Weidenhammer from Dr. David Bailey at the Advanced Physics Lab on September 3rd 2019.
