PM1703MO-1 Portable Radiation Detector

The new energy-compensated PM1703MO-1 combines the functions of radiation detection (CsI based detector) and radiation dose measurement and accumulation (GM tube based dosimeter). This unit is the smallest in size and at the same time offers the highest performance of an instrument of this type currently available on the market. It meets ANSI N42.32 and ANSI N42.33 standards specifications and can be equally well used in health physics as well as security applications. In addition to the basic features of well-known precursor Models PM1703M (gamma only) and Model PM1703GN (gamma / neutron), the PM1703MO-1 additionally features identification and networking capability.

These features include:

  • Bluetooth Connectivity – The instrument may be equipped with Bluetooth transmitter and connect with any Bluetooth enabled computing device, including PDAs, laptops and desk-top computers. It offers the ability to transmit the gross counts for display on the computer screen.
  • Isotope Identification Software – A suite of isotope identification software applications that can be installed on any computer or Smartphone and allow immediate identification and category classification of the alarming isotope(s). Identification of multiple isotopes is also possible.
  • Networking Software –Network software that will allow any Internet enabled computing device to transmit the data via Internet or other communication system to a Unified Command Center (UCC). Through the UCC, users can obtain on-line information about isotope dose rates, isotopes detected and identified, GPS locations of the source (using external GPS options), live mapping of an area and monitoring of radiation levels by each user and by UCC - for the whole area of surveillance.

Decision Support System
A new decision tree logic application allows managers to set up protocols that are fed back to the end users using Q&A and simple logic. Examples include the ability to set up protocol around naturally occurring radiation or medical isotopes. The DSS system allows the UCC users to develop an artificial intelligence module to assist in mitigation of false alarms.
