When you think of a radiation detector, you’re probably thinking of a Geiger tube and its high voltage circuitry. That isn’t the only way to measure gamma radiation, though, and [Alan] has a ...

We only know that he has made one, including a high-voltage power supply, a photomultiplier tube, and–what else–an Arduino. You also need a scintillation crystal to convert the gamma rays to ...

MACE telescope in Ladakh is a cutting-edge gamma-ray observatory aiding in dark matter research and high-energy astrophysics.

It's not easy to imagine how high the frequency of a high-energy gamma ray is. During the time it takes for its wave to go through one cycle, a gamma-ray wave traveling at the speed of light will ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film ...

Future Research and the Mysteries of PeVatrons While the detection of ultrahigh-energy gamma rays from the Milky Way’s center ...

Gamma ray emission causes no change in the number ... All types of radioactive decay can be detected by a Geiger-Muller tube, or G-M tube. The radiations ionise the gas inside the G-M tube and ...

The isotope used must: be a source of gamma rays so that they pass out through the body to be detected by the gamma camera or GM tube; have very short half-lives - sources used typically have half ...

Jamie Carter is an award-winning reporter who covers the night sky. A massive burst of gamma rays produced by the explosion of a star almost two billion light-years away was so powerful that it ...
