What is Tungsten Neutron Capture Reaction Shielding?
Neutron capture is a nuclear reaction process in which an atomic nucleus and one or more neutrons collide with and combine with to create a heavier nucleus. As Neutrons do not have electric charge they can get into a nucleus more easily than positively charged protons, which are driven back electrostatically. Neutron capture assumes a significant role in the cosmic nucleosynthesis of weighty elements. In stars it can move forward in two ways: as a swift (r-process) or a slow process (s-process). Nuclei of masses more than 56 cannot be created by thermonuclear reactions (i.e. by nuclear fusion), but can be made by neutron capture. Tungsten neutron capture reaction shielding can be utilized at the time of neutron capture reaction process to give staff safety, and save the environment.
The Applications of Tungsten Neutron Capture Reaction Shielding
Because of its high density, optimal absorption characteristics against radiation while being environment-friendly, tungsten can be applied to trigger tungsten neutron capture reaction shielding. Neutrons are nuclear capture compound, nucleus is created, and then by discharging one or more gamma ray photons back stress reactions, depicted (n, γ). Discharging the total gamma-ray energy is equivalent to the excitation energy of compound nucleus. Besides, the (n, γ) reaction is the creation of nuclear fuel, transuranic elements and other substantial reactions. For an instance, by reaction (for antineutrinos) can prosuce nuclear fuel plutonium Pu. So, tungsten shielding radiation protection device can be utilized as nuclear fuel and equipment, applied in nuclear fuel research and production fields.
The Advantages of Tungsten Neutron Capture Reaction Shielding
Tungsten, that is a robust and scarce metal and often found out in the form of chemical compound, serving as an effective lead replacement material. Tungsten possesses great density and sturdiness, in fact, almost 60 % greater than lead, that are noted characteristics for radiation shielding applications. It can be utilized to alleviate X-ray and gamma rays. Other advantages of tungsten-based materials straddle their resistance to high temperature and environment-friendliness. At the time of designing of shielding, tungsten alloy radiation shielding is counted in accordance with needs of shield to cut down the multiple thickness of shielding materials.
