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 ...

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 ...

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

"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 ...

Radiotherapy is one of the most widely used therapies for cancer treatment. It consists of using radiation in its different forms (X-rays, Gamma rays, particles) to harm and destroy tumours, either ...

and X-rays. The tour ends with gamma rays, the potentially deadly radiation discussed in the program Death Star. Flash is a plug-in that allows for increased interactivity. If you can see the ...

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 ...

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

It does this by emitting a high energy electromagnetic wave called a gamma ray. Gamma radiation does not consist of particles but as short wavelength, high energy electromagnetic radiation emitted ...
