Now here’s a product I hope I never need! The RDTX Pro Radiation Detector from Scosche is an iPhone/iPod touch accessory that measures ambient radiation. The RDTX Pro has a solid-state design to accurately measure gamma radiation without calibration. It can be used alone as radiation alarm; it is powered by a 96-hour battery in independent mode. When connected to the Apple device, it will draw power from the device. The free Scosche radTEST app has an analog display to show radiation levels as safe, elevated, or dangerous. The digital display shows detailed radiation measurements. You can share your measurements with friends around the world using social media. The RDTX Pro Radiation Detector is $349.99 from Scosche, though the website shows it’s temporarily out of stock.
