The PM1703MO-1A and PM1703MO-1B instruments combine features of both SPRD and dosimeter in the one housing. Theirs small-sized GM tube allows for measuring dose and dose rate of the gamma radiation in the wide energy range while highly sensitive CsI(Tl) scintillation detector allows for searching of the radioactive and nuclear materials and primary radionuclide identification of the radioactive sources.

The PM1703MO family instruments combine functionality of the Spectroscopic Personal Radiation Detector (SPRD) and dosimeter in the one housing. The highly sensitive CsI(Tl) detector enables prompt gamma radiation detection, source location and primary radionuclide identification. The GM tube based detector ensures precise dose and dose rate measurement.
The Spectroscopic Personal Radiation Detector consists of two separate parts:
The external computing device such as PDA, laptop, or PC can be used to run PoliIdentify software. The communication between the detector and the external computing device is carried out either via USB (PM1701MO-1A) or Bluetooth (PM1703MO-1B) channel.
The separation of the detection and data processing parts of SPRD suite provides high flexibility in the configuration and number of benefits to the end-user. For example, the radiation detector can be used as a conventional standalone personal radiation detector (PRD). If there a need for the isotope identification capabilities the PRD can be upgraded to enable identification and networking capabilities without hardware replacing and/or significant modification. Additionally, communication via Bluetooth allows distance separation between user and the radiation source while instrument is operating and providing additional protection to the user from unnecessary radiation exposure.
The PM1703MO-1A / B SPRD models have following functions:
In addition to the on-site identification, the SPRD models have networking capabilities giving the ability to transmit data via internet for the off-site analysis and isotope identification.
The summary of the additional features of SPRD models in respect to their basic precursor model PM1703MO-1:
USB or Bluetooth Connectivity
PM1703MO-1A has USB and PM1703MO-1B has Bluetooth channels. This provides the ability to transmit the gross counts and accumulated spectra to an external computing device, such as PDA, laptop and/or desk-top computer. The Bluetooth function also allows user to be at a safe distance from the radiation sources while the SPRD is in operation, providing and additional degree of user protection from the radiation exposure by distance.
Isotope Identification Software Suite - PoliIdentify
A suite of isotope identification software applications that can be installed on an external computing device such as PDA, laptop, or PC and allows immediate identification and category classification of the alarming isotope(s). Simultaneous identification of multiple isotopes is possible. Identification software can be utilized in two operation modes: automatic mode for non-trained users and expert mode for advanced users.
Networking Software
Real time data exchange between a user on-site and a remote Unified Command Center (UCC). The Polimaster Nuclear Protection Network (NPNETTM) system is available to experts at UCC. Through the NPNET, experts can obtain real-time information about dose rates, gamma scintillation spectra, detected and identified isotopes, instrument’s GPS locations, live mapping of the area, and monitoring of radiation levels for the whole area of surveillance.
