Observations from high-flying aircraft revealed that thunderclouds act as natural particle accelerators, emitting energetic ...

Like ultraviolet radiation and X-rays, gamma rays can kill microorganisms and are used to sterilize food and other objects, such as medical instruments and equipment. Gamma radiation is also a ...

shortest of all known rays, the gamma rays given off by radium. On the infra or long wave side of visible light come infrared, then longer heat waves (16 mil-lionths to 12 thousandths of an inch ...

Gamma-ray bursts (GRBs) are the most energetic events ever observed in the universe. These powerful outbursts can shine a ...

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 ...

New research suggests that the largest cosmic structure is even bigger and closer to Earth than we knew. It goes against ...

Light, heat, radio transmissions, and medical X-rays may not seem ... ultraviolet radiation, and X-rays. The tour ends with gamma rays, the potentially deadly radiation discussed in the program ...

The device can be used by industrial and medical radiation users ... beta radiation composed of electrons or positrons, electromagnetic X-rays and gamma-rays, and neutron radiation. The new detector ...

we will establish an imaging method to visualize line X-ray gamma-rays from activated materials in general. We will expand this method to the fields of space, medicine, and pharmacology, and establish ...

CT scans are an essential tool used to diagnose a range of medical conditions ... On the other side is high-frequency, short-wavelength radiation that includes ultraviolet (UV), X-rays and gamma rays.

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 ...
