Internet or similar to immediately view the designated item. 1.2 The RADEAGLET The RADEAGLET is a new generation radio-isotope identification device (RIID). It consists of the following components: • Scintillation detector using either a sodium iodide NaI(Tl) crystal.
RADEAGLET to a computer. All common operating systems like Microsoft Windows, MacOS or Linux are supported. The internal battery of the RADEAGLET is charged while connected through this plug to a computer (slower charging) or a power adapter (faster).
1.3 User and Instrument Safety Do not unscrew the housing of the RADEAGLET. There are no user servicable parts inside. Various components inside the RADEAGLET use high voltages posing a severe health risk for you. The detector crystals built into in the RADEAGLET are brittle. To enjoy a long-lasting performance of your instrument, avoid drops or other impacts.
2 Using the RADEAGLET Before you start the RADEAGLET for the first time, ensure the battery is fully charged. To check this, plug in the provided charger (Figure 4, p. 11) and let it charge until the green LED (Figure 1, p.

RADEAGLET passes by a radiation source. 2.6.3 Neutron Source Detection (Optional) The RADEAGLET has an optional neutron detector installed. If you are close to a neutron source, there are several visual indications that warn or alarm you about it: •...
2.7 Easy-Id Mode for Rapid Nuclide Identification A primary objective of RADEAGLET is to identify the source of radiation. For performing a quick identifi- cation, RADEAGLET features the so-called EASY-ID MODE. In this mode, a time preset (as defined in the SETTINGS menu) is used to acquire a spectrum of the source.

The RADEAGLET always stores two data files in two different formats. For details please see 3.3.6, p. for more about loading and saving of spectra. For the EASY-ID example in Figure 13, p. 21, you will find two separate files *.spe and *.n42 if you download the data to your computer.
3 Advanced Mode 3.1 Entering the Advanced Mode This section will show how to personalize the measurement experience with RADEAGLET. To change the SETTINGS of the device, enter the ADVANCED MODE. Press the RIGHT button to leave the DOSE RATE MODE and enter the ADVANCED MODE. Press the CENTER button again to toggle through the different submenu and enter them by pressing SELECT.
Plutonium is highly toxic, especially if ingested or inhaled. If the RADEAGLET identifies a source as plutonium (as WGPu or RGPu), you should under no circumstances touch the source.
*.n42 has become the world-wide standard for spectrum files and the list of supporting programs is growing steadily. To store a spectrum press SAVE. To reload a spectrum, press LOAD. The RADEAGLET can store up to 1 million spectra. Each record contains the associated nuclide identification result.
Figure 20: Confirmation after saving the spectrum The energy-channel ratio of the RADEAGLET scales the energy E=3072 keV to channel 2048 (2k). In- ternally, the RADEAGLET uses 4096 channels for the spectrum processing. Changing the x-axis scaling also affects the cursor. The instrument will show the cursor position either in channel numbers or energy units (whatever is selected).
The live time will always be shorter than the real time. RADEAGLET allows you to review the real-time and live-time by toggling between them. This can be done by pressing the LIVE button or the REAL button. The dead-time is the time difference between real-time and live-time.
The calibration has a tremendous impact on the measurement quality of the instrument. It determines the precision of the current calibration by locating the peak at the correct position. The RADEAGLET has a dedicated screen to visually inspect the calibration quality when performing a calibration in the CALIBRATION MODE.

Cs and the calculated centroid is the calibration error. The RADEAGLET is a stabilized instrument and it is not expected that the peak positions will drift much. Sometimes a recalibration is still needed because environmental circumstances might be unfavorable for the background stabilization.
You can adjust the display brightness in the SYSTEM SETTINGS by changing the numerical value for the brightness. Small values indicate a low intensity and high values correspond to high intensity. RADEAGLET also features an automated energy saving feature which dims the light after a certain time. This can be changed in the display timeout in the SYSTEM SETTINGS.
3.6.9 Setting Warning and Alarm Thresholds for Dose Rate The RADEAGLET offers different types of annunciation to inform the user about the strength of the radiation field. Using these settings, the minimum dose rate for a warning and the minimum dose rate for calling out an alarm can be defined.

Centroid Center of a peak. The centroid is used to measure peak position. Its numerical value is often generated by a peak fit routine. In the RADEAGLET, a peak fit is performed in the CHECK-CAL screen, presenting you the centroid and resolution of the peak.

Scintillation detector The primary detector for radiation used by the RADEAGLET is the scintillation detector. The scintillation detector consists of a crystal coupled to a photomultiplier. Once radiation passes through the scintillation crystal, atoms of the crystal material become excited to higher energetic levels.
As temperature changes are encountered, modern scintillation based instruments must apply some means of stabilization. Shown below is the procedure the RADEAGLET uses to correct for peak shifts and to adjust the peaks in the spectrum to their scientifically correct positions.
Nuclide identification results depend on the quality of the spectrum. For extremely high count rates, the scintillation spectrum degrades and for dose rates greater than 200 µSv/h at the detector surface, the RADEAGLET switches off the scintillation subsystem and uses the fall-back GM tube (included in all RADEAGLET variants) for dose rate measurements.
C Troubleshooting C.1 Checking the Proper Function of the System To ensure your RADEAGLET is working properly, we will supply a short checklist for successful operation. 1. Check the status of the battery failure LED a) After some time, the booting screen of the RADEAGLET should appear.
C.2.1 System Switches Back to Black Screen Solution: Unplug all cables from RADEAGLET. Open rear battery chamber and set the “on/off“ switch to “off”. Wait at least 10 seconds. Put the switch back to the “on” state. If the problem reappears, please contact our customer support.
