Explore gamma rays. Learn the definition of a gamma ray and see its characteristics. Find the sources of gamma rays on Earth and outer space, and...
The method utilising a portable gamma-ray source and a Geiger-Mueller counter has been applied in laboratory conditions for determinations of gamma-ray absorption coefficient in wood of several deciduous softwood species. Results might be of importance in characterising the wood tissue and also in ...
of the spectrum are gamma rays. These have the shortest wavelength, the highest frequency, and the most energy. Humans can only detect a small portion of theelectromagnetic spectrumwith our eyes:visible light. All the colors of the rainbow (ROYGBIV) are part of the visible light spectrum. ...
Radiation from the higher-energy end of the ultraviolet spectrum, in addition to X-rays and gamma rays, is known as ionizing radiation: It is energetic enough to be able to knock electrons off of atoms, turning the atoms into ions. Ionizing radiation can damage DNA and cause a multitude of...
Food irradiation is a process of applying ionizing radiation. It enhances and extends the shelf life of food by eliminating or reducing insects and microorganisms. Radiation (such as electron beams, gamma rays, or x-rays) is emitted by radioactive substances or produced electrically. ...

Gamma ray, electromagnetic radiation of the shortest wavelength and highest energy. Gamma rays are produced in the disintegration of radioactive atomic nuclei and in the decay of certain subatomic particles. It includes some overlap with X-rays in the el
electromagnetic radiation, in classicalphysics, the flow ofenergyat the universalspeed of lightthrough free space or through a material medium in the form of theelectricandmagnetic fieldsthat make up electromagnetic waves such asradio waves,visible light, andgamma rays.

light,X-rays, andgamma rays. All of these waves travel at the same speed—namely, thevelocity of light(roughly 300,000 kilometres, or 186,000 miles, per second). They differ from each other only in thefrequencyat which their electric and magnetic fieldsoscillate....
Example:Any form of light haselectromagnetic energy, including parts of the spectrum we can't see. Radio,gamma rays, x-rays, microwaves, andultraviolet lightare some examples of electromagnetic energy. Sonic Energy Sonic energy is the energy of sound waves. Sound waves travel through mediums, s...
