- Gamma-rays have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum. These waves are generated by radioactive atoms and in nuclear explosions. Gamma-rays can kill living cells, a fact which medicine uses to its advantage, using gamma-rays to kill cancerous cells. Gamma-rays travel to us across vast distances of the universe, only to be absorbed by the Earth's atmosphere. Different wavelengths of light penetrate the Earth's atmosphere to different depths.

Radioactivity Gamma rays are electromagnetic waves of very short wavelength and high frequency. Gamma rays are emitted by most radioactive sources along with alpha or beta particles. After alpha or beta emission the remaining nucleus may still be in an excited energy state. By releasing a gamma photon it reduces to a lower energy state. Gamma rays have no electrical charge associated with them.

Radioisotopes in Medicine External irradiation (sometimes called teletherapy) can be carried out using a gamma beam from a radioactive cobalt-60 source, though in developed countries the much more versatile linear accelerators are now being used as high-energy X-ray sources (gamma and X-rays are much the same).

Gamma Rays Gamma ray is a electromagnetic radiation with a very short wavelength. It means, it is of high frequency. Gamma radiation is produced by interactions of sub atomic particles like fusion, fission, radioactive decay and electron-positron annihilation. Gamma rays can create great damage to living tissues since it is a type of ionizing radiation. You should be careful not to be hit with this radiation. There are different properties that govern gamma rays. These are shielding, matter interaction, light interaction and gamma ray interaction.

Gamma ray Gamma rays are emitted during nuclear fission in nuclear explosions. Gamma ray (also called gamma radiation), denoted by the lower-case Greek letter gamma (γ or γ {\displaystyle \gamma } ), is penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei. It consists of photons in the highest observed range of photon energy.

- X-ray and gamma ray devices are different and used for different purposes. X-ray radiography devices are powered by electricity. When the device is turned off, x-rays are not produced. X-ray radiography generally creates very clear pictures. The devices are large and good for use in factories.

- Gamma rays are dangerous because they cause cellular damage that leads to DNA damage, cancer and radiation sickness. Because gamma rays are such a high-intensity, ionizing form of radiation, they pass through normal protections, such as skin, clothing, foil and goggles. Only high-mass shielding, such as lead, can stop them. Continue Reading.

Types of Radioactive Emissions Gamma Rays and X Rays. Gamma and x rays (also called photons) are waves of energy that travel at the speed of light. These waves can have considerable range in air and have greater penetrating power (can travel farther) than either alpha or beta particles.

- X-rays and gamma rays-Higher tier. X-rays are manufactured by an x-ray machine. A hot cathode emits electrons that are attracted to a tungsten anode. When the fast-moving electrons hit the metal target, most of their kinetic energy is transferred to heat but some is transferred to x-rays.-rays, gamma rays and beta particles are all used in medicine to treat internal organs. X-rays are produced by firing electrons at a metal target and gamma rays are emitted by the nucleus of radioactive atoms. Gamma rays are used to kill cancer cells, to sterilise medical equipment and in radioactive tracers.

Radiation Therapy for Cancer External-beam radiation therapy is most often delivered in the form of photon beams (either x-rays or gamma rays) (1). A photon is the basic unit of light and other forms of electromagnetic radiation. It can be thought of as a bundle of energy. The amount of energy in a photon can vary.

Radiation Basics A gamma ray is electromagnetic radiation (similar to visible light, but at a much higher energy in the electromagnetic spectrum) given off by the nucleus of an atom as a means of releasing excess energy, and is oftentimes released when an atom undergoes decay by emitting an alpha or a beta particle.

Gamma Rays Gamma rays have the smallest wavelengths and the most energy of any wave in the electromagnetic spectrum. They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes.

X-ray As a result, the term X-ray is metonymically used to refer to a radiographic image produced using this method, in addition to the method itself. Since the wavelengths of hard X-rays are similar to the size of atoms they are also useful for determining crystal structures by X-ray crystallography.here is no universal consensus for a definition distinguishing between X-rays and gamma rays. One common practice is to distinguish between the two types of radiation based on their source: X-rays are emitted by electrons, while gamma rays are emitted by the atomic nucleus.

Electromagnetic Spectrum X-Rays can cause cell damage and cancers. As the wavelengths of electromagnetic waves get shorter, their energy increases. Gamma rays are the shortest waves in the spectrum and, as a result, have the most energy. Gamma rays are sometimes used in treating cancer and in taking detailed images for diagnostic medicine. Gamma rays are produced in high energy nuclear explosions and supernovas.

Astronomy Gamma ray astronomy is the study of astronomical objects at the shortest wavelengths of the electromagnetic spectrum. Gamma rays may be observed directly by satellites such as the Compton Gamma Ray Observatory or by specialized telescopes called atmospheric Cherenkov telescopes.

Incredible hulking facts about gamma rays Gamma rays are the most energetic type of light, packing a punch strong enough to pierce through metal or concrete barriers. More energetic than X-rays, they are born in the chaos of exploding stars, the annihilation of electrons and the decay of radioactive atoms.

- Because Gamma rays can kill living cells, they are used to kill cancer cells without having to resort to difficult surgery. This is called Radiotherapy, and works because healthy cells can repair themselves fairly well when damaged by gamma rays - but cancer cells can't. Getting the dose right is very important!
