Many of these alpha emitters are accompanied by x-ray and γ-ray emissions that typically have low emission intensities and, in cases where the parent is at the head of a long decay series, there can be a large number of γ-ray emissions detected from the progeny. Analysis of the spectru...

However, it was not until the that our ability to actually detect these emissions came to pass. Gamma-rays coming from space are mostly absorbed by the Earth's atmosphere. So gamma-ray astronomy could not develop until it was possible to get our detectors above all or most of the ...
Imaging of nuclear gamma-ray lines in the 1–10 MeV range is far from being established in both medical and physical applications. In proton therapy, 4.4 MeV gamma rays are emitted from the excited nucleus of either 12C* or 11B* and are considered
The remaining heart of that star, now know as the Crab Pulsar, continues to confound scientists today by emitting some of the most energetic gamma rays ever observed. A better understanding of these emissions ultimately could help reveal evidence of dark matter, determine how much electromagnetic ...
According to the currently valid definition, X-rays are emitted by electrons outside the nucleus, while the nucleus emits gamma rays. • Gamma rays frequently accompany the emission of alpha and beta radiation. Now that we have some understanding of the characteristics of gamma ray, we are ...
GRBs are immensely energetic explosions that have been observed in distant galaxies. They are the most energetic and luminous electromagnetic events since the Big Bang. The first GRB was discovered in 1967. Since 2019, three GRBs with high energy emissions have been detected and photons up to ...
Gamma rays are the most energetic part of the spectrum. They have the shortest wavelengths and highest frequencies. These characteristics make them extremely hazardous to life, but they also tell astronomers alotabout the objects that emit them in the universe. Gamma-rays do occur on Earth, creat...

Gamma raysthat penetrate the uranium itself must also pass through the container wall to be detected. For example, if the calibration sources have a 1-mm-thick steel wall and the items to be measured/verified have a 2-mm-thick steel wall, uncorrected measurements will be biased toward results...
