Now government researchers at Idaho National Labs have created their own app that uses an ordinary smartphone as a gamma ray detector, put it through its paces in the lab and published the results. The pixels in smartphone cameras can detect gamma rays in the same way as they pick up visible light. So when the lens is covered, the image should reveal evidence of gamma ray exposure once other noise has been removed, such as that from heat and current leakage. These guys have tested several types of Android smartphone with a variety of gamma ray sources at various different doses. The researchers say the phones give a reasonable measure of radiation dose, can detect the direction of source (by comparing the measurements from the front and back cameras) and can even measure the energy of the gamma rays by measuring the length of the tracks that appear in the image. While the results do not match the quality of bespoke detectors, that may not matter since in many circumstances cellphones are likely to be the only sensors that are available. That could be useful for emergency services, air travelers wanting to monitor their extra radiation dose on routes over the arctic and people who live in areas with a higher than average background radiation level."TFA states that the "may" release the app but there are already a few gamma radiation detectors on the Play Store for Android such as these:

https://play.google.com/store/apps/details?id=com.rdklein.radioactivity&hl=en [google.com]
Basically you cover the lens with black tape to block light but of course gamma radiation can get through. The apps need to be calibrated to your individual phone since random noise in the sensor can give false readings. The apps provide a method to do that.

It comes from the soil of the desert Southwest. Inhaled, it can cause incurable, even fatal illness. And, thanks to 'global warming, valley fever is spreading fast. Death Dust.
Texting is so yesterday. Now there is a new thing that is fast catching on.

Jim Ewing Shares On Nehemia 8:10
Nehemiah 8:10....
.
Our circumstances must never be our strength, because they can change so quickly, as can our surroundings, our moods, our desires. The world depends on superficial and transitory things for strength because those things are all that they have, or else they imagine something bigger than themselves, but usually something quite general (non-specific) that may see them through, but the believer has as his or her Protector the One Who spoke the universe (and everything in it) into existence, and His reality is not simply imagined.
God never promised us a rose-covered pathway (I know that from experience, and so do you!), but He does promise us that He will never leave us or forsake us- EVER. We must always remember that... As believers, we need to keep in mind that He is ALWAYS with us- every moment that we live, and then the very moment that we breathe our last- He takes our hand and brings us to Himself, for all eternity...Yes, we are in very good Hands, indeed!......
.
The biggest problem that we have concerning this truth is that we don't spend enough time contemplating His Presence. You notice I didn't say that we don't spend enough time IN His Presence, for we are ALWAYS in His Presence, but we need to ponder this fact, and trust that He knows our estate, that nothing that happens in our life escapes His Knowledge and attention....
.
Easy to say when things are going smoothly, isn't it? But it is true in the most absolute sense, regardless of our present circumstances. Is there a secret to always knowing His Presence and care? Well, the very Son of God didn't simply rest in the fact that He knew who He was, He sought the Father EARLY, before the crowds came. He coveted the Presence of His Father! Do we covet the Presence of our heavenly Father?
.
How about King David, "O God. thou art my God; EARLY will I seek Thee, my soul thirsteth for Thee, my flesh longeth for Thee in a dry and thirsty land, where no water is." (Psalm 63:1)......
Do we pant after Him like the deer panteth after the water (psalm 42:1)? Do you feel it as you read it? Now, tell me- is there a 'secret' to always knowing God's Presence and care- to always trusting God, no matter what? Read what the scripture tells us, and ponder the depths of His wonderful Word. His Spirit is bearing witness with what you have read. Seek Him early, and with all your heart....
En Agape,
Pastor Jim Ewing
