The patented* GammaPix™ technology, available exclusively from Image Insight Inc. and authorized partners, provides low-cost, widespread detection and monitoring of ionizing radiation. Our software uses the inherent sensitivity of digital cameras to gamma radiation allowing billions of unmodified and internet-connected CCTV security cameras, webcams, smartphone cameras, and tablet cameras to detect the telltale signatures created when gamma rays interact with the camera’s image sensor.  The algorithms detect radioactivity threats and everyday sources such as exposure from medical patients, on high-altitude airplanes, or from highly contaminated products. GammaPix™ can be used to prevent terrorist attacks using REDs or Dirty Bombs, and to help secure radiation sources in hospitals or industrial sites that could be used in such devices.

GammaPix™ detects X-rays, gamma rays, some beta particles, and high energy neutrons. Exact performance depends on the camera model, image sensor, electronics, and firmware. Scene brightness impacts sensitivity for CCTV security camera applications. Sensitivity has been measured from 20 keV to 1.3 MeV, and is consistent with other silicon-based detectors, depending upon camera construction. Generally, plastic-housed devices show enhanced sensitivity below ~200 keV – achieving peak sensitivity near 100 keV of ~250% of that measured at 662 keV.  

Plot shows 5,500 independent two-minute measurements of a decaying Tc-99m (140 keV) source over more than 20 hours (2.3 half-lives). Nine (9) different camera units were tested at once (differences in distance account for slight vertical offsets). The red- line shows the expected decay curve. Note the consistency of measurement across 9 sensors with hundreds of measurements each.

GammaPix™ Pro smartphone apps can measure 20 μSv/hr (2 mRad/hr) within ~15 sec. GammaPix™ software running on exposure-optimized cameras with a covered lens detects 1 μSv/hr (0.1 mRad/hr) in <2 min. GammaPix™ running on security video cameras detect ~ 50 to 150 μSv/hr (5 to 15 mRad/hr) within ~30 sec.

Plot shows 500 independent measurements, on each of 10 different optimized camera units of a decaying positron-emitting radio- isotope source (511 keV) over more than 18 hours. Each point is from a two-minute measurement and is sufficient to measure 10 micro-Sieverts/hr (0.1 mRad/hr) with good repeatability. Variations in distance account for the vertical offsets. Note the consistency of measurement across 10 sensors and more than 5,000 individual measurements. Any threat-level source within a few hundred meters would be detected in under a minute.

GammaPix™ Training Simulator provides Live Virtual training capability.  Training with realistically threat-sized radiation sources is expensive, dangerous and impractical. In addition, tTraining with real radiation sources restricts the size and realism of your scenario.   Solve both these problems with the GammaPix™ Training Simulator system.

The GammaPix™ Training Simulator App runs on unmodified smartphones and connects with the GammaPix™ Command Center web application. Scenarios are constructed and controlled using the Command Center. During exercises, the Training Simulator App communicates with the Command Center to determine what radiation level would be measured if the scenario were real. In automatic mode, the app alarms once significant radiation levels are detected. In active mode, trainees use the app to measure and localize the radiation source, and to determine safety cordon locations. Dose estimates are made automatically.

Radioactivity emergency response training exercises are often conducted with live sources at special locations. For safety reasons, the sources are smaller than would typically be encountered in a real emergency, but large enough to demonstrate the use of measurement equipment. Requiring special security, such exercises rarely take place in the relevant environments, never in well populated areas, and usually with a Radiation Safety Officer standing nearby. The GammaPix™ Training Simulator software avoids these limitations and complements live-source training by using simulated sources to create a Live-Virtual training environment. Exercises are conducted at low cost, and with maximum convenience in locations of your choosing.

Set up your scenario on a cloud-based map interface using a web browser and click to configure source sizes and locations. Command staff monitors the training scenario remotely or on scene, in real-time or in play-back for after action reviews.

Trainees use apps to report the dose from any location using multi-layered security infrastructure. 

Automatic measurements alert personnel to dangerous (simulated) radiation levels.

Dose estimated for each responder.

GammaPix™ Pro software provides the lowest cost, networked, ionizing radioactivity awareness capability with no extra equipment needed.  GammaPix™ Pro software enables radiation detection using unmodified commercial, off-the-shelf cameras in smartphones and tablets. Wherever the user is, the GammaPix™ Pro app automatically measures radioactivity levels to check the safety of the local environment. Your readings, along with those of your team and personal users in the local area, contribute to community protection from radioactivity terrorism and radiological accidents.

GammaPix™ Radioactivity Detection Software uses the inherent sensitivity digital cameras have to detect gamma radiation. This software allows billions of unmodified, internet- connected surveillance cameras, webcams, smartphones, and tablet computers to detect the telltale signature created when gamma rays interact with the camera’s digital image chip. GammaPix™ software has twice been designated a Qualified Anti-Terrorism Technology (QATT) by the U.S. Department of Homeland Security.

GammaPix Common Center™

The GammaPix™ Command Center web application fuses numerous detection devices into a coherent monitoring network. With it, data from a defined group (e.g., a hospital, police precinct, HAZMAT team, or security company) can be monitored for exposure anomalies or lost sources. Radioactivity and time-tagged location data are collected from mobile and fixed cameras and are securely transferred to Image Insight’s secure cloud servers, your organization’s on- premises server, an AWS GovCloud provisioned secure data enclave, or another similar resource. Data owners and group subscribers use the Command Center to map, visualize, and analyze the radiological threat environment. Leaders and authorized headquarters staff can issue commands to deployed devices. In this way, ionizing radiation detection parameters can be altered without distracting personnel from their operational activities.

Image Insight’s GammaPix™ Pro app securely communicates readings to third party applications such as BTACTM and Blueforce Command CenterTM, DoD’s ATAK, and others to provide pervasive radiological situational awareness to frontline responders.

The GammaPix™ Command Center, in addition to controlling the scenario, also receives, stores, and plots the radioactivity data from the trainees for use by the Incident Commander. Optionally, it issues commands to change the operation of the app, such as increasing the measurement frequency or to poll all devices to measure radiation at that moment. The system allows real-time monitoring of the First Responder’s performance, as well as training incident commanders. Click- drag-type scenario creation enables Training Officers to quickly develop scenarios for various learning objectives. Accelerated play-back of the exercise supports post-event evaluation of the training event and supports development of after-action reports.
