Scintillation Detector

  • The scintillation detector collects the pulse height spectrum of gamma photons that interact with the scintillation crystal.
  • Each radioisotope has a specific decay scheme, and some emit gamma photons that can be analyzed to determine the radiation source.

Geiger-Mueller Detector

  • The Geiger-Mueller detector measures dose rates up to 1 Sv/h when the scintillation detector exceeds 200µSv/h.
  • Warning: if the Geiger-Mueller detector kicks in, the user is in an extremely dangerous level of radiation and should increase distance and shielding between themselves and the source.

Neutron Detector

User Interface and Layout

  • The RADEAGLE's user interface has a STATUS BAR at the top that indicates battery level, time, and current mode.
  • The MENU BAR is at the bottom of each screen and consists of three fields that correspond to the hardware keys.
  • The instrument's keyboard has four colored LEDs that provide visual information: blue for neutron alarm (optional), red for gamma alarm, green for battery charging state, and orange for failure.

Preparations for Start-up and Initial Self-Stabilization

  • Before starting the RADEAGLE, ensure the battery is fully charged.
  • The instrument performs an initial stabilization process during start-up, which takes about 80 seconds and involves temperature checks and peak searches in the spectrum.
  • The RADEAGLE continuously monitors and adjusts the gain based on temperature during operation.

Dose Rate Mode

  • The instrument's display starts up in the DOSE RATE MODE, which shows the ambient H*(10) dose rate in units of µSv/h or mR/h.
  • The DOSE RATE MODE has a colored bar that provides a visual interpretation of the dose rate and helps users qualitatively determine whether the radiation is strong or not.
  • The instrument can be set to alert users with visual, tactile, and acoustic alarms if the dose rate exceeds the warning and alarm thresholds.

Detect Mode

  • The DETECT MODE is used to find radioactive sources by evaluating the incoming radiation strength in terms of count rate.
  • The instrument automatically performs a background acquisition in the DETECT MODE and detects sources by comparing the count rate to the background level.
  • The DETECT MODE has a colored bar graph that aids users in finding sources, with green bars indicating radiation levels close to the background, yellow bars indicating a slight increase in radiation, and red bars indicating increased radiation potentially caused by a source.

EASY-ID Mode

  • The EASY-ID MODE is used for rapid nuclide identification and has a visual guidance that helps users establish a favorable distance to the source.

  • The EASY-ID MODE features an automatic saving of spectra and their results, which can be loaded and saved in different formats.### ADVANCED MODE
  • In the SETTINGS section of the ADVANCED MODE, you can reset the instrument to factory settings by pressing RESET.

SPECTRUM MODE

  • SPECTRUM MODE is used for spectroscopic analysis of the radiation field spectrum.
  • The instrument can be used as a small portable gamma spectroscopy field laboratory.
  • The screen layout of the SPECTRUM MODE is split into three main areas of information:
    • Green box: 2D plot of counts (y-axis) versus channels (x-axis) or energy (x-axis).
    • Blue box: Data representation (LIN, LOG or SQRT) and length of the spectrum (2048).
    • Red box: Dose rate (DR) in rem or µSv/h, real/live time (RT and LT), gamma counts (GAMMA) in cps, gross-counts (GrossC), and dead time (DT).
  • In SPECTRUM MODE, the user can:
    • Perform a manual acquisition by pressing START and STOP.
    • Trigger a nuclide identification by pressing ANALYZE.
    • Use the CURSOR to evaluate the spectrum and move it along the x-axis.

CURSOR

  • The CURSOR can be moved along the x-axis using the < and > buttons.
  • The CURSOR position reveals the number of counts located at the specific energy.

ZOOM

  • ZOOM allows the user to magnify the spectrum at the location of the cursor.
  • In ZOOM view, the movement of the CURSOR is much finer than in the standard view.

Loading and Saving Spectra

  • Spectra can be saved in two formats: IAEA spectrum format SPE and ANSI N42.42 standardized N42 format.
  • Each spectrum contains the associated nuclide identification result.
  • The filename is a unique specifier of the spectrum and is composed of the date-time configuration and a unique index number.

Changing the x-axis and y-axis Scaling

  • The x-axis can be toggled between energy [keV] and channel [ch] display.
  • The y-axis can be toggled between linear, logarithmic, and square root data representations.

CALIBRATION MODE
