The cosmic pinwheel that astronomers feared could one day shower Earth with lethal gamma rays may not be as dangerous as once ...

That isn’t the only way to measure gamma radiation, though ... The detector circuit uses a miniature solar cell and a JFET wired up in a small brass tube to block most of the light and to ...

Changing these interactions can lead to different chemical reactions and malfunctioning cells in our bodies. Gamma rays are a particularly damaging form of ionizing radiation because their high ...

The U.S. Naval Research Laboratory (NRL), in partnership with NASA's Marshall Space Flight Center (MSFC), has developed ...

"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 ...

A new study explains how thunderstorm electric fields produce strong gamma‐ray glows with oscillating gamma‐ray rates, and that these oscillations develop into intense pulse trains that closely ...

Nuclear power has long been a reliable energy source, supplying nearly 20% of electricity in the United States. While it does ...

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 ...

WEST LAFAYETTE, Ind. -- An international team of astronomers has observed extremely rapid bursts of high-energy gamma rays from a distant galaxy, an observation that is challenging how astronomers ...

Our skin and mucous membranes protect us like vigilant sentinels against the onslaught of harmful pathogens. This extraordinary defense owes its strength to epithelial cells—specialized tissues woven ...

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 ...
