Gamma rays are produced by a number of astronomical processes in which very high-energy electrons are produced. Such electrons produce secondary gamma rays by the mechanisms of bremsstrahlung, inverse Compton scattering and synchrotron radiation. A large fraction of such astronomical gamma rays are screened by Earth's atmosphere.
One of those was deflected by a magnetic field (as were the familiar "canal rays") and could be identified with Rutherford's beta rays. The last type was a very penetrating kind of radiation which had not been identified before. Villard was a modest man and he did not suggest a specific name for the type of radiation he had discovered.
The history of gamma-ray [1] began with the serendipitous detection of a gamma-ray burst (GRB) on July 2, 1967, by the U.S. Vela satellites. After these satellites detected fifteen other GRBs, Ray Klebesadel of the Los Alamos National Laboratory published the first paper on the subject, Observations of Gamma-Ray Bursts of Cosmic Origin.

[28] [29] Hearing of Henri Becquerel's experience with uranium, Rutherford started to explore its radioactivity, discovering two types that differed from X-rays in their penetrating power. Continuing his research in Canada, in 1899 he coined the terms "alpha ray" and "beta ray" to describe these two distinct types of radiation. [30]
The following year Henri Becquerel was experimenting with fluorescent uranium salts, and wondered if they too might produce X-rays. [3] On 1 March 1896 he discovered that they did indeed produce rays, but of a different kind, and even when the uranium salt was kept in a dark drawer, it still made an intense image on an X-ray plate, indicating ...
The brightest gamma ray burst ever detected recently reached Earth. It’s 70 times longer than any other burst we’ve spotted. Scientists Have Found the 'BOAT' Gamma Ray Burst—the Brightest of ...
Likewise, gamma radiation and X-rays were found to be high-energy electromagnetic radiation. The relationship between the types of decays also began to be examined: For example, gamma decay was almost always found to be associated with other types of decay, and occurred at about the same time, or afterwards.
This gamma-ray burst, researchers said on Tuesday, caused a significant disturbance in Earth's ionosphere, a layer of the planet's upper atmosphere that contains electrically charge
