"Over the last decade, people have discovered that these high-energy gamma rays are present in many, many types of very energetic astronomical phenomenon, but we don't know much about where they ...

Gamma rays are also used to produce medical images and to sterilise medical instruments, in a similar way to X-rays. They are also used to sterilise food, killing bacteria in fresh fruit and ...
