• detect neutron radiation with count rate and accumulated counts (available only for variants equipped with a neutron detector) The identiFINDER R425 is the modern successor of the identiFINDER R400. It is well-known around the globe and in daily use by thousands of users hunting for sources of ionizing radiation.
1 Welcome In particular, the technology in the identiFINDER R425 is devised to identify threat objects. A threat object is defined as radioactive material whose signature is consistent with that of material that could be used for terrorist purposes. Threat materials are usually those used in a nuclear explosive device or which could be used in Radiological Dispersive Devices ("dirty”...

1 Welcome Safety Warnings The FLIR identiFINDER® R425 is designed for indoor and outdoor use. When operated in accordance with the operating instructions, it should not present any hazard to the operator. The housing is essential to the integrity and safe operation of the instrument. Under no cir- cumstances should the housing be tampered with, penetrated, or otherwise removed except for normal access to the external connectors (see chapter 7).
Page 15
For more information, see "Replacing Batteries" on p. 151. The two USB-C ports may be used to connect the identiFINDER R425 to an external computer for char- ging, mass storage, or displaying the web interface (Chapter 8).

1. Shut down the instrument by pressing and holding the Power button (2.10 below). 2. Start up the instrument (2.3 on page 24). 2.10 Shutting Down the R425 Several methods are available to shut down the identiFINDER R425. To shut down the R425 during normal operations: 1. Press and hold the Power button.
Page 41
From the shutdown prompt shown in Figure 2-27, you can press R to cancel the shutdown and resume normal operation. If you are shutting down the identiFINDER R425 while an alarm is raised, the end time of the alarm entry is not stored in the data- base.
3 Operating the identiFINDER R425 Operating the identiFINDER R425 This chapter provides a guide to the basic operating procedures necessary to scan an object for radiation and generate the analyzed results of the scan. Your organization may use a Standard Operating Procedure (SOP). If so, refer to the SOP.
Figure 3-2 : Surveying an object with the identiFINDER R425 To scan an area for gamma radiation: 1. Move the identiFINDER R425 to different locations in the environment under survey. Observe the display. The current dose rate is displayed in large digits and as a bar chart (Figure 3-3).
Surveying for neutron radiation is like surveying for gamma radiation, with the following modifications to the procedure: 1. When moving the identiFINDER R425 to different locations in the environment under survey (see p. 44, step 1), position the neutron detector close to your midsection as shown in Figure 3-4.
If the radiation detected in your survey exceeds one of the thresholds defined in the identiFINDER R425's settings, the identiFINDER R425 initiates an alert. If popups are enabled in your alarm indicator settings (see section 6.5.4.5, "Alarm Indicators" on p. 95), the Alarm Status screen (Figure 3-5) will appear, displaying information about the warning or alarm condition.
Figure 3-7: Finder mode: object scan with elevated radiation Identify the Nuclide The identiFINDER R425 can identify a number of nuclides by analyzing the radiation spectra they emit. After detecting a radiation source by surveying the ambient dose rate in Dose Rate mode (3.2) or by loc- ating the source's position in Finder mode (3.4), use the R425’s Identify mode to identify nuclide pro-...
Page 49
1. From the Dose Rate mode display, press ) to switch to Identify mode. Identify The identiFINDER R425 begins to acquire a spectrum of the radiation. By default, identifications are performed in static mode, mean- ing there is a preset length of time for acquiring spectrum data.
Page 50
3 Operating the identiFINDER R425 When you are in the correct position, the screen will display "Don't Move" (Figure 3-9, bottom). Figure 3-9: Identify mode: Finding the position for best measurements 3. Wait until the identification has completed. The R425 applies the identification algorithm to the acquired data, and the Result screen (Figure 3- 10) will display.
See "Connecting to an External Computer" on p. 123 or consult an IT administrator for help. 1. Connect the identiFINDER R425 to a computer with the included USB cable via one of the two USB ports on the device, as described in Chapter 7.
You will be prompted to set parameters for the file such as the compression type and file type. Switch Off After completing all measurements, shut down the identiFINDER R425. Other scenarios for shutting down are described in "Shutting Down the R425" on p. 40. The basic shutdown procedure is: 1.
Displays the Main Menu (see p. 69). 4.2 Finder Mode Use the identiFINDER R425 in Finder Mode to locate a radiation source. Immediately after switching to Finder mode, the R425 begins a background measurement (Figure 4-4). Move the instrument around the vicinity of a suspected source and monitor the device display and any other indicators that are enabled in your settings (LEDs, vibration, and beeper) for changes.
Page 58
Figure 4-4: Finder mode: Initial background measurement If a background has been measured during a session (i.e., since you switched on the identiFINDER R425) and there is no time to measure a new background, it is possible to cancel the current background measurement.
R425 User Manual Alarms When radiation passes through the identiFINDER R425, this radiation signature, when above certain thresholds the user specifies (see "Dose Thresholds" on p. 90), triggers an alarm signal that is generated by the detector. 5.1 Alarm Indicators...
Neutron Alarms Available only for variants equipped with a neutron detector. The identiFINDER R425 continuously compares the number of detected neutrons per given period against thresholds specified in the instrument's settings (see section 6.5.4.2, "Neutron Thresholds" on p. 91. When a threshold is exceeded, an appropriate warning or alarm is raised and reported visually on the screen (Figure 5-5) and by the blue neutron LED, depending on your alarm indicator settings.

The Refresh Rate value is the time interval represented by one column in the history chart of the Finder mode (see Figure 6-16). The identiFINDER R425 averages the count rate for the Refresh Rate value specified. At the end of each period, a column is added to the Finder mode graph (see p.
Radiation | Nuclide Settings Settings | Advanced | Nuclides The identiFINDER R425 contains a built-in library used to identify the nuclides causing gamma radiation. The Nuclide Settings menu option allows you to control which information from the Nuclide Library is dis- played during identification.
Radiation | Alarm Settings Settings | Advanced | Alarm The identiFINDER R425 reports various events with on-screen messages. You can also set it to report events, especially alarms, with other methods. You can set each of the alarm indicators independently.

This screen contains fields for defining nine levels of dose rate values. These values are completely cus- tomizable by the user. When the identiFINDER R425 is in Level mode, the defined level numbers, instead of units of measure, will display on the screen to indicate the current radiation level.
