Neutron Activation Analysis (NAA) is a highly sensitive and accurate method for identifying elements in a material sample by targeting it with neutrons from a radioactive source. It can detect about 65 different elements and has many applications in various fields. The method is very versatile and can analyze samples in solid, liquid, and gaseous […]
Neutron stars are supercompressed objects formed from stars that have run out of nuclear fuel and collapsed inward. They are about 20 km in diameter and have a gravitational field 2 x 10^11 times stronger than Earth’s. The density is so great that atoms fuse to form electrically neutral neutrons. Neutron stars rotate rapidly and […]
Neutron radiation, composed of neutral subatomic particles found in nuclear reactors and bombs, is a health risk and the fourth major type of radiation. Discovered in the 1930s, it played a crucial role in the first nuclear reactor and bomb. Neutron radiation tends to be absorbed by nuclei, making it radioactive and dangerous to humans. […]
Neutrons are subatomic particles found in all conventional matter except hydrogen. They are electrically neutral and tightly bound to protons in the atomic nucleus. Neutrons are responsible for half the weight of conventional matter. They were discovered in 1930 and are made up of two down quarks and one up quark. Understanding neutrons has been […]
Neutron detectors are expensive and sensitive instruments used to detect neutrons, which are subatomic particles of interest to physicists and industries dealing with radioactive materials. They are challenging to detect due to their lack of electric charge and small size. Neutron detectors use scintillation detectors or gas-filled detectors to detect the reactions left behind by […]
Neutron beams are streams of electrically neutral subatomic particles found in the nuclei of chemical elements. They have many applications in materials science, medicine, and security. Neutron generators produce neutron beams by firing deuterium or tritium ions at targets. Neutron beams are very penetrating and can detect the positions of atomic nuclei within a material. […]
When a massive star runs out of nuclear fuel, it forms an iron core that collapses into neutronium, a state of matter where electrons and protons fuse into neutrons. This collapse creates a supernova that results in a neutron star, which is incredibly dense and can emit radio or X-ray waves. Some neutron stars, called […]
The neutron bomb is a small thermonuclear device that kills enemy troops with radiation while causing minimal damage to the surrounding area. It was invented by Samuel T. Cohen in the 1970s and is also known as an Enhanced Radiation Bomb. The bomb emits energized free neutrons that can penetrate several feet of earth and […]
