What are gamma rays made up of? Gamma Rays: All the atoms are composed of the nucleus with protons and neutrons as part of the nucleus. The nucleus may sometime get unstable due to some reason and achieve stability after undergoing a radioactive decay. This decay is of three types, alpha...
Why is the sun a source of non-ionizing radiation? Which type of electromagnetic radiation has the highest frequency? Sunlight is a form of energy called What type of electromagnetic waves reach the Earth? What are gamma rays made up of?
Gamma rays are a form of electromagnetic radiation. They can be used to treat cancer, and gamma-ray bursts are studied by astronomers.
Gamma-ray astronomy has become a rich field of research and matured significantly since the launch of NASA's Compton Gamma Ray Observatory in April 1991. Studies of the diffuse gamma-ray emission of the Galaxy can now be performed in far more detail and extended into the MeV regime, ...
Gamma rays, or γ-rays, represent the most dangerous result of radioactivity to humans. They are massless because they are not particles at all. "Rays" is actually short for the general term electromagnetic radiation (EM radiation), which travels at the speed of light (denoted c, or 3 ×...
Readers including Patrick Falini of Baltimore, Md., pointed out a new research paper finding evidence that Earth was hit by a storm of gamma raysabout 1,200 years ago,perhaps set off by the collision of two black holes, or of two very old neutron stars. The gamma-ray storm of 1,200...
It absorbs and, in many cases, emits electromagnetic radiation in the form of gamma rays, visible light, infrared, and more. It can generate magnetic fields of various sorts and strengths. Matter has mass, creating the force of gravity, the effects of which can be readily observed. All ...
irradiated with a 1-gray dose of gamma rays—equivalent to 300 typical medical X-rays. To distinguish cells from the two embryos, they marked one set, chosen at random, with a fluorescent dye. Cells from fathers irradiated up to five weeks before conception ...
In 2013, NASA's Fermi Gamma-ray Space Telescope released results from observing two supernova remnants in the Milky Way: IC 433 and W44. Among the products of these star explosions are gamma-ray photons, which (unlike cosmic rays) are not affected by magnetic fields. The gamma rays ...
