Scintillation detector detects radiations from radioactive emissions. Radiations are produced during nuclear fusion or nuclear fission or any other nuclear reaction. Neutrons are parts of an atom and are emitted as radiations from an atom. When neutron radiation falls on a surface it produces unique signature which can be detected. When neutron radiations interacts with specific materials, the chemical reaction produces compounds which identify neutron radiation. Gamma radiations are electromagnetic radiations that are produced by nuclear reactions along with neutrons. Gamma radiation upon interaction with neutron radiation produces a unique compounds that helps in the detection of neutrons. The objective of gamma neutron scintillation detector is detection of neutrons. Other type of neutron detectors are gas flow detectors and semiconductor detectors. Scintillator is a type of material that emits radiation or flash of light when excited by radiation. Scintillation detector is a combination of scintillator and an electronic light sensor such as photomultiplier tube. Photomultiplier tube on absorbing the radiation emit electrons. The electric energy emitted from these electrons are analyzed and the type of particle that collided with the detector is identified. Pulse shape discrimination (PSD) technique is used to differentiate gamma-rays and neutrons.
In gamma neutron scintillation detector, a luminescent material is used can be either a solid, liquid or gaseous material. When gamma rays fall on scintillation material, its atoms are ionized and excited to a lower energy state and emit radiations of photons. In pure inorganic scintillation material when the atom returns to lower-energy state they emit low radiations of photons. When small amount of impurities known as activators are added to pure organic scintillation material the radiation of photons increase.
Rising demand for application such as radioisotope Identification devices (RIDs), spectroscopic personal radiation detectors (SPRDs), personal radiation detectors (PRDs) are increasing the demand for gamma neutron scintillation detector. Also radioactive emissions are used to understand the internal crystal structure of materials which is leading to the rise in gamma neutron scintillation detector.
A restraint in development of gamma neutron scintillation detector market is difficulty in detecting neutrons due to background noise. Background noise is caused by alpha particles, beta particles and photons which are known as gamma rays. Alpha and beta can be separated from neutron by shielding materials. But gamma rays cannot be obstructed by physical barriers and when mixed with neutron they behave similar almost similar to neutrons and make detection of neutrons very difficult.
Global gamma neutron scintillation detector market can be segmented by scintillation material type, application and geography. The market when segmented by scintillation material type are organic and inorganic. Organic scintillation material include liquids, plastics, anthracene and other such materials. Inorganic scintillation material which are commonly used such as lithium iodide (LiI), zinc sulfide (ZnS), cesium iodide (CSI) and sodium iodide (NaI). The market when segmented by application are medical imaging, material science, nuclear non-proliferation monitoring, nuclear and particle physics research, nuclear power generation, oil & gas exploration, and other such applications.
