GammaPix 3.0.1

The GammaPix™ App, originally developed for several federal agencies, transforms a smartphone into an ionizing radiation detector. This application diverges from typical Geiger counter alternatives by employing the phone's cameras to detect radiation. The GammaPix technology has undergone successful testing in independent laboratories using calibrated sources. Its development received support from notable organizations, including the U.S. Department of Defense, the Domestic Nuclear Detection Office (U.S. Department of Homeland Security), and the Transportation Research Board (U.S. National Academy of Sciences), which encouraged its public release.

For those concerned about accidental exposure to radioactive materials or potential terrorist acts, the GammaPix App offers a timely alert for radiation presence using just the smartphone’s camera. While it should not replace dedicated ionizing radiation detectors, it serves as a rapid and convenient tool for preliminary threat assessment.

It is important to note that this application functions as a tool and various factors may affect the accuracy of its measurements:

• Real-time mode: Observe results while taking a reading.
• Three-stage mode: Provides quick warnings of potential danger followed by a full-length reading for lower doses.
• Camera options: Compatible with both front and rear cameras.
• Calibrations: Designed for iOS devices, particularly the iPhone 5S and earlier models.
• Map display: Visual representation of readings on a map.

Prior to initial use, a 10 to 20 minute initialization period is required for each camera. While this step may appear to delay usage, it is crucial for achieving optimal results. It is recommended to perform this initialization in an area suspected to be free from excessive radioactivity, ensuring that the device is cool and unplugged.

For enhanced performance, ensure that no light interferes with the camera while operating the GammaPix app. Placing the device in a pocket or covering it with an object such as a book works effectively. Electrical tape can also help block light exposure.

The reading process typically spans approximately 3 to 5 minutes when radiation levels are stable; however, imminent danger will be reported more swiftly. It should be noted that certain phone models may not support the app effectively due to limitations in camera optimization at low light levels, leading to disproportionately bright images. Moreover, some individual iOS 8 devices may face compatibility issues.

Disclaimer: The radiation detected by the camera can pose health risks and potentially damage the device. Various factors may compromise measurement reliability or result in inaccurate readings.
