Gamma rays are a form of electromagnetic radiation. They can be used to treat cancer, and gamma-ray bursts are studied by astronomers.
Who discovered gamma rays? What can stop gamma rays? What is electromagnetic radiation made up of? What is gamma ray imaging? What is the frequency of gamma rays? What is a gamma ray burst? How are gamma rays detected? What's the difference between x-rays and gamma rays ...
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, ...
All of the GRBs we have detected have been from galaxies far outside theMilky Way, so in these cases, the gamma-rays aren't very powerful by the time they reach us and thus don't pose too much of a threat, Schroeder explained. But if a GRB were to occur very close to us and h...
In a PET scan, the injected radioactive tracer decays producing a positron. The positron annihilates with an electron to produce two coincident\(\gamma\)-photons with an energy of 511 keV, which are detected by a gantry of detectors surrounding the patient. The precision with which the system...
Gamma Brainwaves Gamma rays are the fastest of brain waves (high pitch, like a flute), and relate to simultaneous processing of information from different brain areas. It passes information rapidly, and as its most subtle of the frequencies, the mind has to be quiet to access it. It is hi...
What animals can see gamma rays?EM Spectrum Vision:The visible spectrum part of the electromagnetic (EM) spectrum is a very narrow region of the EM spectrum. It comprises a small portion of what is really "out there" in the universe, but some animals/species have developed the physical ...
gamma rays: generalHigh signal-to-noise ratio spectroscopic observations of the BL Lac object S4 0954+65 at the alleged redshift z=0.367 are presented. This source was detected at gamma frequencies by the MAGIC (TeV) and FERMI (GeV) telescopes during a remarkable outburst that occurred in ...
In the 1960s,according to the American Physical Society, physicists Robert Pound and Glen Rebka shot gamma-rays first down, then up the side of a tower at Harvard University. Pound and Rebka found that the gamma-rays slightly changed frequency due to distortions caused by gravity. ...
