Gamma rays are very high frequency electromagnetic waves usually emitted from radioactive decay with frequencies greater than 10 19 Hz. The wavelengths of ultraviolet, X-ray, and gamma-ray regions of the EM spectrum are very small.

Both require thick layers of heavy material, such as lead or concrete for shielding.

Gamma rays are electromagnetic radiation with an energy level above a specified amount / wavelength shorter than a specified amount. Electromagnetic wave is a kind of energy being propagated even through free space (vacuum).

Gamma rays are shown at the bottom.


They have a wide range of wavelengths covering orders of magnitude with part of the wavelength range being the same as the range of x-rays, where the difference is determined by HOW the electromagnetic wave was generated. Ultraviolet radiation falls in the range from a few electron volts to about 100 eV. A photon is an elementary particle - a packet of electromagnetic radiation. As of now, they are the most energetic form of electromagnetic radiation in a range greater than 100 keV.

Gamma rays do not have “the” wavelength. Gamma rays are distinguished from X-rays by their origin. Gamma-rays have a wavelength range below 100 pm and frequencies greater than 10 Hz.

The discovery of gamma rays is generally credited to French physicist Henri Becquerel in 1896. Gamma rays are distinguished from X-rays by their origin. Gamma rays are the highest energy photons (shortest wavelength, highest frequency), arising out of nuclear events during radioactive decay. Wavelength, Frequency, and Energy. 2.1 Nuclear (Gamma-Ray) Imaging.

Gamma rays do not have “the” wavelength. Wavelength range: m < 10-11: Frequency range : Hz > 3×10 19: Energy range: eV > 10 5 Whole sky image by the EGRET instrument, aboard the Compton Gamma-Ray Observatory, of gamma rays above 100 MeV. Electromagnetic wave is a kind of energy being propagated even through free space (vacuum). They have the shortest wavelength of the four types. They are invisible to the human eye. Gamma rays have the shortest wavelength. X-Ray Spectrum and Applications: X-rays are part of the electromagnetic spectrum, ... (or gamma rays) depend only on their wavelength and polarization.

X-rays originate outside of the nuclei.

Instead of using wavelengths, astronomers that study these portions of the EM spectrum usually refer to these photons by their energies, measured in electron volts (eV). For in vivo applications, the best gamma rays are of low energy (100–511 keV) because they can penetrate tissues.

They have a wide range of wavelengths covering orders of magnitude with part of the wavelength range being the same as the range of x-rays, where the difference is determined by HOW the electromagnetic wave was generated. A high frequency form of electromagnetic radiation, gamma radiation is known to cause types of cancer and other medical issues in human beings.
Gamma Rays. Gamma-ray astronomy is the astronomical observation of gamma rays, the most energetic form of electromagnetic radiation, with photon energies above 100 keV.Radiation below 100 keV is classified as X-rays and is the subject of X-ray astronomy..
