  • Page 9: About Your Model 700E Series Unit

    Section Introduction About Your Model 700e Series Unit The Ludlum Model 700e series includes the Model 702e, 703e and 711e. They are portable radioisotope identification (RID) systems that detect and identify multiple nuclides, providing quantified results using time-slice analysis. The 700e series of instruments use an externally housed NaI detector. The external detector eliminates the need for an embedded source to provide gain stabilization and self-calibration and allows for meeting ANSI N42.34 standard.
  • Page 10 Model 702e, 703e, 711e Technical Manual Section 1 The Model 700e series unit can be connected to a remote computer using an Ethernet cable, and accessed with either Quantum™ MCA (standard) or Quantum™ Gold (quantitative analysis) software. The Quantum™ software allows: Up to eight MCAs to be controlled at one time, with full spectrum data in real time.

    To ensure accurate results, it is very important to take frequent background spectra in the actual monitoring location. The background is the point of reference against which readings are measured, and corrects for ambient radioactivity or background radiation from cosmic rays in the area of the detector.
