The Model 970-X Portable Multi-Channel Analyzer (pMCA) offers state-of-the-art signal processing for a wide range of nuclear applications. The electronics couple to a wide range of detector options and allow real-time data processing of gamma, neutron and x-ray radiation. The Model 970-X pMCA is unique in that it can meet many applications as a process monitor, a separate laboratory instrument or integrated into an existing system to perform analysis. The flexible architecture allows utilizing different detectors types (solid-state detectors, scintillators, different sizes, different materials). The modular assembly and small packaging are easy software interface are also well suited for applications in control systems where sample automation or fast screening is required. Consider applications both in Spectroscopy and Spectrometry when evaluating the Model 970-X. The list of applications below contains two classes of instruments: 

  • Spectroscopy for identification of radionuclides including some qualitative measurements that often include count rate and dose rate calculations.
  • Spectrometry for quantitative measurements of radionuclides in terms of activity in Curies or Becquerel.

An application table with General examples follow

  • Nuclear Safeguards
    • Spectroscopy with instrumentation positioned in an area to protect special nuclear material. Identification of material, detect movement of material and can employ alarms.Monitoring of nuclear fuel reprocessing – integrated QC system
  • Food Screening
    • Spectroscopy on food samples to obtain quick identification of radionuclide contamination (Can give some quantitative results). This process may not require a specific quantity of specimen and may not require an efficiency calibration for the detector.
  • Food Analysis
    • Spectrometry on food to determine activity of the specimen. This requires efficiency calibration and specific geometry during measurement (e.g., Marinelli and shielded configuration).
  • Health Physics and Bio Sciences
    • Spectroscopy to determine personnel contamination and levels. Body scanning, blood and urine samples in a lab environment or integrated with lab equipment. This may involve automating a process such as a sample changer for verifying compliance or monitoring personnel before and after decon.
  • Environmental
    • Air sampling and determining levels of radio activity. Analysis in the lab from samples collected. Measurements to determine identification and level of samples after remediation.Measurement of pollution samples (sediments from ponds, lakes, etc.).
  • Waste Management
    • Verification of radioactive waste before shipping or disposing. HLW and LLW catagorization for proper storage and transportation methods. This process may be automated to determine identification of isotopes, related half-life details, and radiation levels. Samples may be from D, waste disposal area, medical, etc. Transportation process control and leak mitigation can also be automated.
  • Nuclear Medicine
    • Spectroscopy to monitor patients – ID and measure dose rate. Spectrometry to perform analysis on patients and perform QC on the process and avoid overdose. Monitoring of activity is completely automated and can be available in real-time (second by second). Real time data can also be interfaced to a controller for auto shut-down or other desired action based on breakthrough of the eluate.
  • Reactor Monitoring
    • Spectroscopy to monitor patients, materials and shipping/stoage processes - ID isotopes and measure dose rate. Spectrometry to perform analysis on patients or stored materials, perform QC on processes and reduce hospital stay-times. Monitoring of activity can be completely automated (area monitoring, laundry monitoring, etc) and can be available in real-time (second by second). Real time data can also be interfaced to additional networks or instruments (conveyor shut down, HVAC suspend, etc). for disposition based on dose, isotope or background changes.
