What is gamma rays?

What Does gamma rays Mean

Ray , originating from the Latin word radius , is the name given to the born line where a certain type of energy is produced and which continues in the same direction where it is radiated.

According to the class of energy , it is possible to distinguish between different rays. The gamma rays , in this sense, are formed by waves generated from the annihilation of particles or by nuclear transition.
This ionizing radiation , which has a great penetrating power and a high energy level, is made up of photons, whose energy is estimated in a unit known as megaelectronvolts or MeV . Due to their properties , gamma rays can cause important alterations in cell nuclei.

Gamma rays can be generated through various processes or produced spontaneously in space. In the latter case, when they emerge from the nuclei of an active galaxy or from a supernova , the rays do not reach the Earth as they are absorbed by the atmosphere. However, they can be observed using telescopes located in space.
The most frequent use of gamma rays is in sterilization . This radiation can be used to kill bacteria from food or to sterilize instruments used in medicine .
Gamma rays are also used for the diagnosis and treatment of various diseases and disorders. As these rays can change the structure of cells and cause cancer, their use requires great control.
Gamma ray buds
Also known simply by its acronym BRG, or its equivalent in English, GRB, gamma ray bursts are flashes of this type of ray that are associated with explosions of considerable energy in galaxies that are located at great distances. These are the most luminous electromagnetic events that take place in outer space. With regard to its duration, it can be as short as a few nanoseconds or as long as a few hours; the normal thing, on the other hand, is that it does not exceed a few seconds.
Gamma ray outbreaks often precede a long-lasting afterglow with radiation at longer wavelengths (radio frequency, ultraviolet radiation, infrared radiation, visible light, and X-rays). Some specialists claim that, in general, gamma ray bursts are beams of light of intense radiation whose rays are oriented in a parallel way (this is technically called collimated light ). Furthermore, they are believed to be produced by a supernova.

A supernova is understood to be a stellar explosion that sometimes manifests itself very clearly in regions of the celestial sphere in which observers had not detected any particular body .
Gamma ray astronomy
Gamma ray astronomy is known as the study of the universe by means of this type of rays, defined in previous paragraphs. Since the atmosphere of our planet does not allow gamma radiation, the first astronomers to observe gamma photons needed rockets and probe balloons; At that time, they could not make very extensive observations, something that has completely changed with the creation of artificial satellites .
To detect this type of radiation, it is necessary to use large devices (similar to the Geiser counter, an instrument for measuring radioactivity levels), the manufacture of which involves the assembly of metal plates of considerable thickness.
Gamma rays usually arise from black holes, collisions at high speeds, particle jets or supernova explosions, among other phenomena of similar magnitude, and for this reason some sources refer to gamma ray astronomy using the name of astronomy of the violent universe .
