Alpha radiation occurs when there are most neutrons in an atom, which causes the atom to turn into an isotope. Alpha radiation is formed due to the atom not being able to sustain the extra neutrons in the nucleus. The atom undergoes radioactive decay, which will emit helium particles (alpha radiation) which consists of two protons and two neutrons in order to stabilize itself.

According to U.S Energy Information Administration, nuclear energy comes from splitting uranium atoms. Atoms contain protons, neutrons and electrons. The neutrons contain a lot of energy. The energy can be released from the neutrons by breaking something called bonds. When the fission happens a neutron that came

Ionizing radiation is a type of radiation that is able to disrupt atoms and molecules on which they pass through, giving rise to ions and free radicals. It is made up of energetic subatomic particles, ions or atoms moving at high speeds, and electromagnetic waves on the high-energy end of the electromagnetic spectrum. There are five primary types of Ionizing Radiation, Alpha Particles, Beta Particles, Gamma Rays, X-Rays and Neutrons. Alpha Particles are charged particles, which are two neutrons and two protons. They have a very limited ability to penetrate other materials, because they travel short distances and they have large mass. The only hazard that the caused is when they are inhaled. Beta Particles are electrons or positrons, which are

Beta Radiation is a high-energy electron that carries a negative charge. That is send out by some radioactive nuclei. And it is ionizing than Alpha radiation and more ionizing than gamma rays. This makes travel through many centimeters or even meters. And millimeters through the skin and tissue.

In nuclear power, there are mainly two nuclear processes to be considered: fission and fusion. In fission, large atoms are split into small atoms, known as fission products. (Touran). These fission products are remnants of uranium nuclei, which then split apart after obtaining a passing neutron (WNA). After obtaining these neutrons, nuclear energy is being produced. Nuclear power plants to this day use this process to produce energy. On the other hand, fusion combines atoms such as hydrogen or helium to produce nuclear energy (Lee). In this process, hydrogen can be manipulated, which then produces energy. To make this happen, heavy-heavy hydrogen, known as deuterium or tritium has to combine together to create helium or a neutron. Deuterium is found in water. Tritium can be created by combining the fusion neutron with lithium, which is a metal that is easily obtainable. Thus, the nuclear process of fusion could be an energy source that has

Nuclear fusion, or the fusing together of light nuclei to form larger ones can create another form of nuclear energy. Essentially, it is the exact reaction that occurs in the sun, as the sun’s heat is created by the bombardment of hydrogen atoms creating helium and a neutron during which energy is

Under the right conditions, we can create a successful nuclear reaction with Uranium-235, a single neutron is fired at a Uranium-235 atom. This neutron causes the uranium to become unstable and split off into separate products, most notably 2 smaller atoms (A known pair of products are Barium-142 and Krypton-91) and 2-3 separate neutrons. These neutrons split off and attach to other Uranium-235 atoms, this is the start of a chain reaction, creating a large amount of heat energy as the reaction continues. This is a common form of nuclear fission, a process in which a large nucleus is forced to split into smaller nuclei, and is used in modern nuclear power plants.

Nuclear chemistry is the study of the chemical and physical changes in the nucleus of an atom. The field of nuclear chemistry deals with radioactive elements such as radium, radon and the whole actinides series and the equipment to deal with such elements; such as nuclear reactors. However the subject itself varies because it deals with the scientific areas such as physics, biology, geology and chemistry. Nuclear chemistry has help us discover more about the nucleus and has provided advances in medicine, nuclear weapons and instruments to help scientists in those fields. 1, 2

In most nuclei of chemical elements is the number of protons in the nucleus is equal to the number of neutrons in the nuclei of some elements , the number of neutrons is

Another use for radiation is in smoke detectors. One sort of smoke detector uses American-241 which emits alpha radiation. The alpha particles pass between two charged metal plates, causing air particles to split into positively and negatively charged ions (which means they ionise). The ions

Nuclear conversion of an atomic nucleus from one form to another is known as radioactivity. These conversions are accompanied by nuclear radiations, major nuclear radiations are alpha, beta and gamma radiations these are ionisations radiations and hence are dangerous to living beings these radiations can cause radiation sickness and sometimes can even lead to death. However these nuclear radiations can be detected and measured and considerable research is also being done on eradicating these nuclear radiations. [1] Molecules and ions

In South Korea, researchers found traces of radioactive gas from North Korea. When they tested for their nuclear weapons, South Korea found and made RAM which is a machine which finds the cause of radiation. There are seven types of radiations such as Gamma-rays, X-rays, Ultraviolet light, visible light, Infrared light, Microwaves, and Radio waves. Radioactive pollution increases in the natural radiation because activities by people. However, the main cause of radiation is nuclear weapons. When we think of radiation, you typically imagine bombs and nuclear explosions. The radiation caused by the creation of nuclear weapons is dangerous and harmful to humans and nature. Radiation is powerful and it moves and spreads out everywhere and is hard to see with naked eyes. Many radioactive elements are used in nuclear power plants and the basic components of nuclear weapons are cesium, strontium, Plutonium, and uranium. It is including chromium, cobalt, cobalt, calcium, iodine, krypton, nickel, radium, strontium, thorium, uranium, and radon.

Fission weapon uses the process of nuclear fission to produce large amount of energy. Uranium-235 is a valuable isotope found naturally on the earth (consists of 0.7% U-235) because it can serve as a primary fuel for a weapon. Fission is induced by the capture of a neutron. When a U-235 atom absorbs a neutron, it splits into two lighter nuclei and the process is accompanied with the emission of several neutrons because the heavy nucleus has a higher neutron to proton ratio than the two fragments. There is also the accompanying emission of gamma rays. The released energy is given by where is the mass lost in the reaction and is the speed of light (universal constant ). This energy is in the form of kinetic energy of the product

Abstract Nuclear Medicine is the branch of medicine concerned with the use of radio-nuclides in the study and the diagnosis of diseases, eg. the assessment of organ function, detection and treatment of some diseases or monitoring of treatment’s effects. It provides physiological (not available from other imaging modalities) and diagnostic information. In the other hand, it uses very small amounts of radioactive material (radiopharmaceuticals, RP) that is introduced into the body and acts as a tracer. Information

Radioisotopes are unnaturally produced unstable atoms of a chemical element which have a different number of neutrons in the nucleus, but the same number of protons and the same chemical properties. May live for only minutes. Their existence is measured in “halflives,” how long it takes for half of the isotope to disappear. (3)
