Scosche Industries has introduced the RDTX-PRO, a hardware radiation detector and software app for iOS devices that detects gamma radiation and requires no calibration. The device can also be used as a standalone radiation alarm separate from the iOS device for up to 96 hours on one AA battery. In combination with the free accompanying radTEST app, it can detect gamma radiation above 60keV within five percent accuracy. Ten dollars of each sale will be donated to charities assisting Japanese earthquake/tsunami relief.
