Page 5: Introduction And Overview
1.0 Introduction and Overview The rad-ID is a complex radiation laboratory in a small box that has been carefully designed to be easy to use. It contains four different types of sensors, each designed to allow an operator to detect, locate, and identify radioactive isotopes. This manual will explain how to use the rad-ID to detect, locate, and identify radioactive isotopes. -
Page 6: Operating Modes
1.1 Operating Modes The rad-ID has only two modes, Detection or Identification. When the rad-ID is first turned on it will measure the background radiation for 30 seconds, and then start with the Detection Mode Summary screen. When the Handle Button is pressed, the rad-ID will go into Identification mode. -

4. A large Helium-3 (He3) sensor. The CZT array is located in the front of the rad-ID. The NaI sensor is located on the right side, under the right-most button. The GM sensor is located in the center. The He3 tube is located on... - Page 8 The sensors are used in the Detection and Identification modes in the following ways: Detection Mode • The NaI sensor is extremely efficient and sensitive at detecting gamma radiation and high- energy X-rays. In the Detection mode, the NaI provides the highest sensitivity of radiation detection..

Page 9: Operating The Rad-Id
2.0 Operating the rad-ID 2.1 Turning on the rad-ID The rad-ID is turned on using the rocker switch on the top panel underneath the base of the handle. ON and OFF are printed on the switch. When the rad-ID is first turned on, it measures the background radiation for a period of 30 seconds. - Page 10 These screens allow the operator to use the rad-ID to quickly track down and identify radiation sources. By moving the rad-ID among packages, vehicles, or people, the operator can quickly identify which is the source of radiation.
-
Page 11: Detection Alarms
When the source of the neutrons (such as a vehicle or package) is identified, put the rad-ID as close as possible and put it into Identify Mode. Be advised that neutron sources cannot be casually shipped and should be accompanied by complete transport documentation. -
Page 12: Identification
After a radiation source is detected, the rad-ID can be used to identify the radioactive isotope. To identify a radiation source 1. Point the front of the rad-ID in the direction of the highest radiation count (the NaI Detection display showing the last 30 seconds is very good for this) 2. -
Page 13: Confidence Bar
2.6 Confidence Bar When an isotope is identified, a confidence bar (made up of little colored rectangles) appears beside it on the right. The longer the bar, the higher the confidence of identification. The length of the confidence bar depends on the number of radiation peaks detected and the consistency of the radiation. -
Page 14: Displaying The Measured Spectra
2.8 Displaying the Measured Spectra Press the Next Page button at any time in Identification mode to cycle through the energy histograms of the CZT sensor and NaI sensor. These histograms show the spectra of the measured isotope in a plot of energy (on the bottom axis) by the number of photons measured at that energy (vertical axis). - Page 15 The closer the rad- ID is to the source, the greater the density of photons that impact the rad-ID’s sensors, and the faster the identification.

Page 16: Shielding
In this example, a small Cadmium-109 sample is shielded. Because part of the Cadmium radiation signature is blocked, the rad-ID will not make an identification. However, if the Display Potential Detections option is turned on (Menu-Settings-Processing Options), the rad-ID... -
Page 17: Masking
The last 50 identifications are continually stored in a large memory loop. This data can be transferred to a PC using the rad-ID PC User software, using either a wireless Bluetooth or serial IRDA datalink. -
Page 18: Nai Calibration
NaI crystal speeds up the calibration. 4. Press “Next Page”. 5. The unit will say when the calibration is completed (30 to 60 seconds). Once a rad-ID is warmed-up, the calibration will last until the temperature of the rad-ID changes significantly. Hold Calibration... -
Page 19: Communicating With A Pc
The rad-ID IRDA communicates only with serial IRDA devices. With the rad-ID User software loaded on the PC, the rad-ID can upload any or all of its stored identification data files. The datalink can also be used to update the firmware of the rad-ID. The rad-ID Bluetooth or IRDA must be turned on by the operator (Menu-Communications- Communications Port). - Page 20 – this will always be 00000000 (8 zeros)]. 5. You now have a Bluetooth connection with your device. And the corresponding COM Port to the rad-ID will be reflected under the ‘Com Ports’ tab. It should also be displayed when you connect to the chem-ID.
- Page 21 The data can then be saved by clicking either the “Save to File” button, to save it as a rad-ID file, or “Save as CSV”, to view it in Microsoft Excel. To view a dataset saved on a PC, just open the rad-ID User Software application, click the “Load from File”, and select the dataset to view.

Page 22: Updating The Rad-Id Firmware
3.3 Updating the rad-ID Firmware Users of the rad-ID will be notified when new firmware builds are available to improve the performance of the rad-ID. Usually these builds add new features or improve the isotope identification library. The rad-ID can be easily upgraded using the following instructions. -
Page 23: Factory Calibration
Each rad-ID is extensively tested and calibrated before it is released to the field. A Calibration Data Set of 9 plots is shipped with each rad-ID. It includes calibration plots of each CZT sensor (there are 8) and the NaI sensor. The CZT calibration curves are generated using a 10 uCi Cesium-137 source and a 10 uCi Barium-133 source held in proximity to each CZT crystal for 60 minutes. -
Page 24: Appendix A: Menu Tree
1.1.1.3.2. Upgrade Firmware • Newer versions of the rad-ID PC software automatically perform this function. In older versions, it places the rad-ID in a ready state so that the firmware can be updated by the rad-ID PC Software. Once activated, the operator is locked-out of the rad-ID until the update is complete and verified. - Page 25 1.1.1.4.Time • Resets the rad-ID internal clock. When the correct time and date is selected, select “Change Clock Now” to implement. Correct local time can also be uploaded using the PC User Software. 1.1.2. Saved Datasets • Allows the operator to look through the previous 50 identifications. If the rad-ID is in communication with a PC, it also allows the operator to upload selected datasets to the PC.
