That isn’t the only way to measure gamma radiation, though, and [Alan] has a great circuit to measure even relatively weak radiation sources. It uses a very small photodiode, and draws so little ...

For that, you need something like this gamma-ray spectroscope. Dubbed the Pomelo by [mihai.cuciuc], the detector is a homebrew solid-state scintillation counter made from a thallium-doped cesium ...

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 ...

is particularly valuable as a non-destructive nuclear method in the measurement of elements that do not form neutron capture products with delayed gamma ray emissions. Inaccurate and incomplete data ...
