Gamma rays are electromagnetic radiation at the short-wavelength, or high-frequency, end of the electromagnetic(EM) spectrum, which ranges from gamma rays(short) to radio(long). The study and analysis of gamma-ray spectra for scientific and technical use is called gamma spectroscopy, and gamma-ray spectrometers are the instruments which observe and collect such data. Because the energy of each photon of EM radiation is proportional to its frequency, gamma rays have sufficient energy that they are typically observed by counting individual photons.  2, record 9, English, - gamma%2Dray%20spectrometer

The method by which incident radiation interacts with the medium to cause ionization may be direct or indirect. Electromagnetic radiations (X rays and gamma photons) are indirectly ionizing; that is, they give up their energy in various interactions with cellular molecules, and the energy is then utilized to produce a fast-moving charged particle such as an electron. It is the electron that then secondarily may react with a target molecule. Charged particles, in contrast, strike the tissue or medium and directly react with target molecules, such as oxygen or water. These particulate radiations are directly ionizing radiations.  1, record 46, English, - gamma%20photon
