GammaPix - Gamma Rad Detection

★★★★★ I cannot possibly express my gratitude to Image Insight for this marvelous App. And I wish all the detractors would stand back and give full appreciation for what they DO have for free. I just completed my second round of RAI and Gamma Pix has been my closest companion and medical advisor to monitor my progress through 18 months of hellish medical process, expense, upset, worry and discomfort. It was on the guide path, the glide path, which delivered me to a CURE. I have defeated cancer. How many people can say that? On my Samsung J700H it ran rock solid across those 18 months and gave consistently accurate spot-readings in both procedures that never failed to impress every radiation technician. THEY do not have tools which can tell them where exactly a patient's readings are highest. I was able to differentiate values between thyroid bed, lymph zones. Various salivary glands, abdomen, liver, kidneys, even bones. This finely-detailed survey yielded a map for future self-monitoring and first line of defense against emergence of follow-on radiation-caused cancers in the affected tissues. I am profoundly grateful. THANK YOU !!

★★☆☆☆ Can't tell if it works well or not. Doesn't work well with a Samsung Galaxy Tab S2. I collect Uranium Ores all of my samples put out at least 30,000 CPM of gamma and beta, not counting alpha. The app only reads 13.5 mSv per hour on my most radioactive thing I have which is a source disc of 10 uCi of Cesium 137.

★★☆☆☆ No calibration for Nexus 6P Gamma Pix doesn't work at all and says light is getting to the camera when the camera is completely covered.

★★☆☆☆ This app used to work, giving me a specific level regardless of "safety" Now it just says "safe" for low levels, making it useless. Even if low levels are in accurate, comparing them to a background level were useful for comparison. I used to be able to detect monazite vs background, or potassium chloride, or 10%thorium welding wire. Now I get nothing. I want to test for radiation existence, not safety, so this device is useless. It can't even detect being in an airplane, which is 3x background during the day, and 2x nighttime background at night. It made a useful tool useless.
