They did, however, by direct comparisons find that these factors were the same for the gamma rays of radium and thorium as for the cosmic rays, thus bringing to light another significant similarity in behaviour of these two types of radiations....

A joint research team made up of Chinese and Japanese scientists has discovered the highest energy cosmic gamma rays ever observed from an observatory in Tibet, opening a new window to explore the extreme universe.The energy of the gamma rays is as high as 450 TeV, equivalent to 45 billion ...
The detection of gamma rays above 100 TeV is a key to understanding the origin of very-high-energy cosmic rays, which has been a mystery since their discovery in 1912. With further observations using this new window, we expect to identify the origin of cosmic rays in our Galaxy," Huang ...
Gamma ray spectrometers are devices that measure the energy of gamma rays emitted by radioactive elements, allowing for the identification of specific elements like potassium, uranium, and thorium based on their energy peaks in the spectrum.
The γ-radiation of a simple radionuclide having a unique γ-energy does not produce a sharp spectral line, but a peak, owing to the statistical nature of the interaction of γ-rays with matter. An NaI(Tl) scintillation detector spectrum for 137Cs is shown in Figure 4. The peak at ...
