Moreover, gamma rays can ionize atoms indirectly and directly (despite they are electrically neutral) through the<strong> photoelectric effect <\/strong>and the <strong>Compton effect<\/strong>. But secondary (indirect) ionization is much more significant.<\/p>\n<p>To describe the principles of detecting gamma radiation, we must understand the <a href=\"http:\/\/sitepourvtc.com\/nuclear-power\/reactor-physics\/interaction-radiation-matter\/interaction-gamma-radiation-matter\/\">interaction of radiation with matter<\/a>, and each\u00a0type of particle interacts differently. Therefore, we must describe interactions of gamma rays (radiation as a flow of these rays) separately.<\/p>\n<h2>Interaction of Gamma Radiation with Matter<\/h2>\n<p><a href=\"http:\/\/sitepourvtc.com\/nuclear-power\/reactor-physics\/atomic-nuclear-physics\/fundamental-particles\/photon\/gamma-ray\/\">Gamma rays<\/a> consist of high-energy <a href=\"http:\/\/sitepourvtc.com\/nuclear-power\/reactor-physics\/atomic-nuclear-physics\/fundamental-particles\/photon\/\">photons<\/a>. These photons are particles\/waves (Wave-Particle Duality) without rest mass or electrical charge. They can travel 10 meters or more in the air, which is a long distance compared to alpha or beta particles. However, gamma rays deposit less energy along their paths. Lead, water, and concrete stop gamma radiation. Photons (gamma rays and X-rays) can ionize atoms directly through the Photoelectric effect and the Compton effect, where the relatively energetic electron is produced. The secondary electron will go on to produce <strong>multiple ionization<\/strong> events; therefore, the secondary (indirect) ionization is much more significant.<\/p>\n<p>Although many possible interactions are known, there are three key interaction mechanisms with the matter.<\/p>\n<ul>\n<li><strong><a href=\"http:\/\/sitepourvtc.com\/nuclear-power\/reactor-physics\/interaction-radiation-matter\/interaction-gamma-radiation-matter\/photoelectric-effect\/\">Photoelectric effect<\/a><\/strong><\/li>\n<li><strong><a href=\"http:\/\/sitepourvtc.com\/nuclear-power\/reactor-physics\/interaction-radiation-matter\/interaction-gamma-radiation-matter\/compton-scattering\/\">Compton scattering<\/a><\/strong><\/li>\n<li><strong><a href=\"http:\/\/sitepourvtc.com\/nuclear-power\/reactor-physics\/interaction-radiation-matter\/interaction-gamma-radiation-matter\/pair-production\/\">Pair production<\/a><\/strong><\/li>\n<\/ul>\n<p>The photon is completely absorbed in the photoelectric effect and pair production, while only partial energy is deposited in any given Compton scattering.

The probability of Compton scattering per one interaction with an atom increases linearly with atomic number Z because it depends on the number of electrons available for scattering in the target atom. The probability of pair production (dominates at higher gamma rays energies), characterized by cross-section, is a <strong>very complicated function based on quantum mechanics<\/strong>. The cross-section generally increases approximately with the square of atomic number <strong>(\u03c3<\/strong><strong>p<\/strong><strong> ~ Z<\/strong><strong><sup>2<\/sup><\/strong><strong>)<\/strong> and increases with photon energy, but this dependence is much more complex.<\/p>\n<p>As a result, effective sensitive material for <strong>gamma radiation detection<\/strong> is, in most cases, based on the use of materials with two following material properties:<\/p>\n<ul>\n<li><strong>high-density of material.<\/strong><\/li>\n<li><strong>the high atomic number of material<\/strong> \u00a0(high Z materials)<\/li>\n<\/ul>\n<h2>Detectors of Gamma Radiation<\/h2>\n<p><strong>Detectors<\/strong> may also be categorized according to sensitive materials and methods that can be utilized to make a measurement:<\/p>\n<ul>\n<li><a href=\"http:\/\/sitepourvtc.com\/nuclear-engineering\/radiation-detection\/ga搜索引擎优化us-ionization-detector\/\"><strong>Ga搜索引擎优化us Ionization Detectors<\/strong><\/a><\/li>\n<li><a href=\"http:\/\/sitepourvtc.com\/nuclear-engineering\/radiation-detection\/scintillation-counter-scintillation-detector\/\"><strong>Scintillation Detectors<\/strong><\/a><\/li>\n<li><a href=\"http:\/\/sitepourvtc.com\/nuclear-engineering\/radiation-detection\/semiconductor-detectors\/\"><strong>Semiconductor Detectors<\/strong><\/a><\/li>\n<\/ul>\n<h3><span id=\"Detection_of_Beta_Radiation_using_Ionization_Chamber\">Detection of Gamma Radiation using Ionization Chamber<\/span><\/h3>\n<p><img loading=\"lazy\" class=\"alignright size-medium wp-image-26132\" src=\"http:\/\/sitepourvtc.com\/wp-content\/uploads\/2019\/02\/ionization-chamber-basic-principle-202x300.png\" alt=\"ionization chamber - basic principle\" width=\"202\" height=\"300\" srcset=\"https:\/\/sitepourvtc.com\/wp-content\/uploads\/2019\/02\/ionization-chamber-basic-principle-202x300.png 202w, https:\/\/sitepourvtc.com\/wp-content\/uploads\/2019\/02\/ionization-chamber-basic-principle.png 451w\" sizes=\"(max-width: 202px) 100vw, 202px\" \/><\/p>\n<p><a href=\"http:\/\/sitepourvtc.com\/nuclear-power\/reactor-physics\/atomic-nuclear-physics\/fundamental-particles\/photon\/gamma-ray\/\">Gamma rays<\/a> have very little trouble penetrating the metal walls of the chamber. Therefore, ionization chambers may be used to detect gamma radiation and X-rays, collectively known as photons, and for this, the windowless tube is used. Ionization chambers have a uniform response to radiation over a wide range of energies and are the preferred means of measuring high levels of gamma radiation. Some problems are caused by alpha particles being more ionizing than beta particles, and gamma rays, so more current is produced in the ionization chamber region by alpha than beta and gamma. Gamma rays deposit a significantly lower amount of energy into the detector than other particles.<\/p>\n<p>Using a high-pressure gas can further increase the chamber\u2019s efficiency. Typically a pressure of 8-10 atmospheres can be used, and various noble gases are employed. For example, <strong>high-pressure xenon (HPXe) ionization chambers<\/strong> are ideal for use in uncontrolled environments, as a detector\u2019s response is uniform over large temperature ranges (20\u2013170\u00b0C). The higher pressure results in a greater gas density and thereby a greater chance of collision with the fill gas and ion-pair creation by incident gamma radiation. Because of the increased wall thickness required to withstand this high pressure, only gamma radiation can be detected. These detectors are used in <strong>survey meters<\/strong>\u00a0and for environmental monitoring.<\/p>\n<h3><span id=\"Detection_of_Beta_Radiation_using_Ionization_Chamber\">Detection of Gamma Radiation using Geiger Counter<\/span><\/h3>\n<figure id=\"attachment_26088\" aria-describedby=\"caption-attachment-26088\" style=\"width: 290px\" class=\"wp-caption alignright\"><a href=\"http:\/\/sitepourvtc.com\/wp-content\/uploads\/2019\/01\/Ionization-Detector-Geiger-Tube.png\"><img loading=\"lazy\" class=\"size-medium wp-image-26088\" src=\"http:\/\/sitepourvtc.com\/wp-content\/uploads\/2019\/01\/Ionization-Detector-Geiger-Tube-300x178.png\" alt=\"Detector of Ionizing Radiation - Geiger Tube\" width=\"300\" height=\"178\" srcset=\"https:\/\/sitepourvtc.com\/wp-content\/uploads\/2019\/01\/Ionization-Detector-Geiger-Tube-300x178.png 300w, https:\/\/sitepourvtc.com\/wp-content\/uploads\/2019\/01\/Ionization-Detector-Geiger-Tube-768x456.png 768w, https:\/\/sitepourvtc.com\/wp-content\/uploads\/2019\/01\/Ionization-Detector-Geiger-Tube.png 820w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><figcaption id=\"caption-attachment-26088\" class=\"wp-caption-text\">The detector of Ionizing Radiation &#8211; Geiger Tube<\/figcaption><\/figure>\n<p><a href=\"http:\/\/sitepourvtc.com\/nuclear-engineering\/radiation-detection\/ga搜索引擎优化us-ionization-detector\/geiger-counter-geiger-mueller-detector\/\"><strong>Geiger counter<\/strong><\/a>\u00a0can detect ionizing radiation such as\u00a0<a href=\"http:\/\/sitepourvtc.com\/nuclear-power\/reactor-physics\/atomic-nuclear-physics\/fundamental-particles\/alpha-particle\/\">alpha<\/a>\u00a0and\u00a0<a href=\"http:\/\/sitepourvtc.com\/nuclear-power\/reactor-physics\/atomic-nuclear-physics\/fundamental-particles\/beta-particle\/\">beta particles<\/a>,\u00a0<a href=\"http:\/\/sitepourvtc.com\/nuclear-power\/reactor-physics\/atomic-nuclear-physics\/fundamental-particles\/neutron\/\">neutrons<\/a>, and\u00a0<a href=\"http:\/\/sitepourvtc.com\/nuclear-power\/reactor-physics\/atomic-nuclear-physics\/fundamental-particles\/photon\/gamma-ray\/\">gamma rays<\/a> using the ionization effect produced in a Geiger\u2013M\u00fcller tube, which gives its name to the instrument.

Scintillation in inorganic crystals is typically slower than in organic ones. They exhibit high efficiency for the detection of gamma rays and are capable of handling high count rates. Inorganic crystals can be cut to small sizes and arranged in an array configuration to provide position sensitivity. This feature is widely used in medical imaging to detect X-rays or gamma rays. Inorganic scintillators are better at detecting gamma rays and X-rays. This is due to their high density and atomic number, which gives a high electron density.<\/li>\n<\/ul>\n<h3>Detection of Gamma Radiation using Semiconductors &#8211; HPGe Detectors<\/h3>\n<figure id=\"attachment_26112\" aria-describedby=\"caption-attachment-26112\" style=\"width: 290px\" class=\"wp-caption alignright\"><a href=\"http:\/\/sitepourvtc.com\/wp-content\/uploads\/2019\/02\/HPGe-Detector-Germanium.png\"><img loading=\"lazy\" class=\"size-medium wp-image-26112\" src=\"http:\/\/sitepourvtc.com\/wp-content\/uploads\/2019\/02\/HPGe-Detector-Germanium-300x204.png\" alt=\"HPGe Detector - Germanium\" width=\"300\" height=\"204\" srcset=\"https:\/\/sitepourvtc.com\/wp-content\/uploads\/2019\/02\/HPGe-Detector-Germanium-300x204.png 300w, https:\/\/sitepourvtc.com\/wp-content\/uploads\/2019\/02\/HPGe-Detector-Germanium-768x523.png 768w, https:\/\/sitepourvtc.com\/wp-content\/uploads\/2019\/02\/HPGe-Detector-Germanium.png 868w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><figcaption id=\"caption-attachment-26112\" class=\"wp-caption-text\">HPGe detector with LN2 cryostat Source: canberra.com<\/figcaption><\/figure>\n<p><a href=\"http:\/\/sitepourvtc.com\/nuclear-engineering\/radiation-detection\/semiconductor-detectors\/high-purity-germanium-detectors-hpge\/\"><strong>High-purity germanium detectors<\/strong><\/a>\u00a0(<strong>HPGe detectors<\/strong>) are the best solution for precise\u00a0<a href=\"http:\/\/sitepourvtc.com\/nuclear-engineering\/radiation-detection\/gamma-spectroscopy\/\">gamma and x-ray spectroscopy<\/a>.<\/p>\n<p>As was written, the study and analysis of gamma-ray spectra for scientific and technical use are called gamma spectroscopy. Gamma-ray spectrometers are the instruments that observe and collect such data. A gamma-ray spectrometer (GRS) is a sophisticated device for measuring the energy distribution of gamma radiation. For the measurement of gamma rays above several hundred keV, there are two detector categories of major importance, <a href=\"http:\/\/sitepourvtc.com\/nuclear-engineering\/radiation-detection\/scintillation-counter-scintillation-detector\/naitl-scintillators\/\"><strong>inorganic scintillators such as NaI(Tl)<\/strong><\/a>\u00a0and\u00a0<strong>semiconductor detectors<\/strong>. If a\u00a0<strong>perfect energy resolution<\/strong> is required, we have to use a\u00a0<strong>germanium-based detector<\/strong>, such as the\u00a0<strong>HPGe detector<\/strong>.

In gamma spectroscopy, germanium is preferred due to its atomic number being much higher than silicon, increasing the probability of gamma-ray interaction. Moreover, germanium has lower average energy necessary to create an electron-hole pair, which is 3.6 eV for silicon and 2.9 eV for germanium. This also provides the latter with a better resolution in energy. The FWHM (full width at half maximum) for germanium detectors is an energy function. For a 1.3 MeV photon, the FWHM is 2.1 keV, which is very low.<\/p>\n<\/div><\/div>\n<div   id="8n9s8rpp6h"     class=\"lgc-column lgc-grid-parent lgc-grid-100 lgc-tablet-grid-100 lgc-mobile-grid-100 lgc-equal-heights \"><div   id="8n9s8rpp6h"     class=\"inside-grid-column\"><div   id="8n9s8rpp6h"    class=\"su-spoiler su-spoiler-style-default su-spoiler-icon-plus su-spoiler-closed\" data-scroll-offset=\"0\"><div   id="8n9s8rpp6h"    class=\"su-spoiler-title\" tabindex=\"0\" role=\"button\"><span class=\"su-spoiler-icon\"><\/span>References:<\/div><div   id="8n9s8rpp6h"    class=\"su-spoiler-content su-u-clearfix su-u-trim\">\n<p><strong>Radiation Protection:<\/strong><\/p>\n<ol>\n<li>Knoll, Glenn F., Radiation Detection and Measurement 4th Edition, Wiley, 8\/2010.
