Gamma rays are high energy electromagnetic waves which are only stopped by thick lead. This means they can easily pass through medical equipment, such as syringes. As gamma rays pass through the ...

Researchers found for the first time evidence that even microquasars containing a low-mass star are efficient particle accelerators, which leads to a significant impact on the interpretation of the ...

Scientists discover low-mass microquasars can accelerate cosmic rays, reshaping theories on high-energy particle origins.

Our home planet is bombarded with particles from outer space all the time. And while we are mostly familiar with the rocky ...

Highly energetic explosions in the sky are commonly attributed to gamma-ray bursts. We now understand that these bursts ...

"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 ...

In a paper published in Scientific Reports, they show that gamma radiation—as opposed to the neutron signals used by traditional monitoring methods—can provide accurate and timely data on ...

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 ...

On March 15, 2024, a space-based observatory detected bursts of low-energy X-rays from deep in the ancient universe, ...

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 ...
