GR-135
THE IDENTIFIER
SYSTEM MANUAL
1.0 GENERAL SYSTEM DESCRIPTION:
The GR-135 - THE IDENTIFIER - represents a major breakthrough in the field of
radiation monitoring, offering the user not only the ability to search for and locate radioactive
material but also to automatically identify the radioactive nuclides present. This capability in a
fully portable hand-held unit will permit its use in a wide variety of applications including :
- Hazard identification and risk assessment
- Inspection of incoming and outgoing material for radioactive contamination
- Inspection of radioactive gauges for leaks
- SEARCH of waste sites for radioactive material
- Employee exposure rate and dose monitoring
- Radioactive source monitoring
- Government inspection for material compliance
- Identification of unknown radioactive material
- Regulatory control of radioactive material
- Classification of radioactive material for a wide variety of users
1.1 GR-135 HARDWARE VERSIONS
a) GR-135 – the basic GR-135 model is a 2-detector system – utilizing a Sodium-Iodide detector
for high sensitivity and a G-M detector for extended Dose Rate range. This model replaces the
older GR-130 model
b) GR-135N – a 3-detector system – in addition to the Sodium-Iodide detector and G-M
detector there is an additional NEUTRON detector
c) GR-135CN – a 4 detector system - in addition to the Sodium-Iodide, G-M and NEUTRON
detectors this model incorporates an additional CZT detector for special applications.
d) DOCKING STATION – all of these models can be supplied with a Docking Station, which
permits operation in a special AUTOMATIC mode highly suitable for semi-technical users
(Appendix A).
1.2 GR-135 OPERATIONAL MODES
The GR-135 can be operated in 2 different modes.
a) AUTOMATIC MODE – restricted to SEARCH and IDENTIFY functions only. All other functions
are disabled to simplify system use by non-technical personnel – available only to DOCKING-
STATION users
b) MANUAL MODE – unrestricted system operation
Selection between modes is via a special switch in the battery compartment to restrict
unauthorized adjustments.
1.3 SOFTWARE RELEASES
This manual describes the current software release as defined in the title, all information
regarding system software or hardware changes and improvements are detailed in Appendix Y.
