All forms of electromagnetic radiation, whether they're called waves or rays, are generated by particles in motion. In a radio signal, for example, negatively charged electrons quickly move back ...

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 ...

From the warm glow of the sun to audible radio waves and invisible gamma rays, electromagnetic waves (action between particles that have an electric charge) surround us. But did you know that there's ...

Among the most fascinating phenomena are gamma rays, the most energetic form of electromagnetic radiation. Recently, scientists have observed that gamma rays from deep space have penetrated Earth ...

Figure caption, Each region of the electromagnetic (EM) spectrum has a range of wavelengths associated with it. Radio waves have the longest wavelengths and gamma rays have the shortest wavelengths.

Changes in atoms and their nuclei can cause electromagnetic waves to be generated or absorbed. Gamma rays are produced by changes in the nucleus of an atom. They are a form of nuclear radiation.

An international team of astronomers reports the detection of four new gamma-ray millisecond ... rotating neutron stars emitting a beam of electromagnetic radiation. The most rapidly rotating ...

The University of Jyväskylä (Finland), in collaboration with the Finnish Radiation and Nuclear Safety Authority (STUK), has ...

Food irradiation has numerous benefits: Eliminates microbial contamination: Destroys bacteria, moulds and yeast that cause food poisoning and spoilage. Lowers food-borne disease risk: Reduces the risk ...

Electromagnetic radiation is the general term for the more familiar light and radio waves, but also includes gamma rays, x rays, ultraviolet rays, and infrared. All of these forms of electromagnetic ...

CT scans are vital for effectively diagnosing problems with bones, muscles, organs and blood vessels. But overuse could be ...
