PRODUCT INFORMATION

EM/Gammalert

Features:

• Ionizing Radiation Detection - The EM/GAMMALERT contains two high-speed radiation detectors - a sensitive CsI(Tl) (thallium-doped cesium iodide) scintillator-enhanced PIN 4-photodiode cluster feeding a picoampere-bias amplifier, and a second PIN photodiode with high dynamic range, not overloaded by intense radiation. Together these detect irradiance up to 300 mW/cm2 and energy 0.01-40 MeV, covering X-ray and Gamma, characterizing not only traditional ionizing radiation levels from a nuclear accident or event, but also intense millisecond-scale lightning-induced TGBs, which may pose a potential health risk. The unit emits an audible beep, and illuminates the LED RED if a hazardous ionizing radiation level has been detected, even if for under 1ms. This RED LED remains lit until reset by pressing the button. Lower radiation levels, as occur from nuclear fallout or ordinary background events, momentarily illuminate the LED in GREEN, and emit a beep. The user may later connect the EM/GAMMALERT to a computer, via a USB-C cable, to view the event(s) in detail. Alternatively, the EM/GAMMALERT may be left continually connected to any computer for real-time display of events as they come in.
• High-Level Electromagnetic Energy Detection - The EM/GAMMALERT contains four embedded antennas in the exposed portion of the PCB on each side of the case. These antennas feed fast high dynamic range circuits to detect EMP and DEW bursts as short as 500 nanoseconds which, although detectable by large conventional spectrum analyzers and receivers, are too short for classification by prior portable microwave field meters. The EM/GAMMALERT emits a beep, and illuminates the LED in RED if a hazardous level of EM is detected, such as from a DEW. This RED LED remains lit until reset by pressing the button. Lower EM levels, e.g. from a nearby transmitting towers, momentarily illuminate the LED in GREEN..
• Internal Storage For Up To 1024 EM and/or Gamma flux intensity event waveforms - The EM-Gammalert stores the energy waveform of each of up to 1024 events (either ionizing or electromagnetic radiation) in its internal flash.
• Worldwide Data Aggregation, Characterization, Display and Global Hazard Recognition - The host computers perform analysis and classification and, with user permission, can automatically upload the event waveforms to a global SQL database on a cloud server for time-correlation with other instruments, for rapid worldwide hazard-trend recognition and analysis.
• An example program (with included source code) allow users to immediately begin acquiring data and, if desired, modifying this program for custom applications.
• Windows 10/11 (64-bit) drivers
• Linux (64-bit) device drivers.
• Powerful Qt GUI included.
• Timestamping
