Subatomic particles gamma

Radiation sterilization involves the exposure of medical textile products to radiations such as electron beams. X-rays, gamma rays, or subatomic particles. Gamma rays are very penetrating and are commonly used for the sterilization of disposable medical... 

Uranium has two major isotopes, (99.3 %) and (0.7 %). is relatively plentiful and stable, while is scarce and radioactive. Radioactive isotopes are susceptible to, and often spontaneously undergo, fission. During fission, the nucleus of an atom splits, several smaller atoms are produced, and energy and subatomic particles (gamma radiation, neutrons, alpha, and beta particles predominantly) are released. In addition to spontaneous fission, fission can also be induced when the... 

X-rays, or gamma rays generated by nuclear decay. Ionizing radiation also includes several types of subatomic particles, such as beta radiation (high-energy electrons) and alpha radiation (helium ions) and others. Medical X-rays are an example of a common beneficial exposure to ionizing radiation. Nuclear radiation is used to generate electricity and cure disease, but is also an important element in military weapons. Uses of nuclear radiation pose serious issues of human exposure and environmental contamination. 

Thus it was the physicists who took the next steps toward understanding the nature of matter. In 1896 the French physicist Henri Becquerel discovered radioactivity, and in 1897 the English physicist J. J. Thomson discovered the first subatomic particle, the electron. Subsequently, studies of the radiation emitted by radioactive atoms showed that these atoms emitted radiation of three different kinds, which were called alpha, beta, and gamma after the first three letters... 

Radioactivity—Spontaneous release of subatomic particles or gamma rays by unstable atoms as their nuclei decay. 

A radioactive isotope radionuclide is an atom with an unstable nucleus, which is a nucleus characterized by excess energy available to be imparted either to a newly created radiation particle within the nucleus or to an atomic electron. The radionuclide, in this process, undergoes radioactive decay and emits gamma ray(s), subatomic particles, or both. Radionuclides occur naturally, but can also be artificially produced. 

Alpha Particles are subatomic particles made up of two neutrons and two protons ejected from the nucleus of an unstable atom. These particles are not able to penetrate most materials-even a piece of paper or the outer layer of human skin can block an alpha particle. However, when alpha-emitting un.stable atoms are inhaled, alpha particles become panicularly dangerous because they will kill lung cells, which could lead to scarring and po.ssible cancer. Gamma radiation is a packet of energy, sometimes called a photon, that is emitted from the nucleus of an unstable atom. 

Radioactive nuclides contain atoms that disintegrate by emission of subatomic particles and gamma or X-ray photons. In alpha decay, a helium nucleus of 2 protons and 2 neutrons is emitted and reduces the mass number by 4 and the atomic number by 2. In beta decay, an electron - produced by the disintegration of a neutron into a proton, an electron, and an antineutrino - is emitted from the nucleus and increases the atomic number by 1 without changing the mass number. Sometimes a positron together with a neutrino is emitted. And sometimes an electron may be captured from the K (outermost) sheh of the atom the resultant electron hole in the K shell is filled by electrons from outer orbits and causes the emission of X-rays. Alpha and beta decay generally leave the resultant daughter nuclei in an... 

Certain elements are radioactive because their nuclei are unstable and spontaneously decay through the ejection (or capture) of subatomic particles, often accompanied by the emission of high-energy electromagnetic radiation. The principal radioactive decay processes are alpha decay, beta decay, gamma emission, and spontaneous fission. 

As the name suggested this type of radiation consists of subatomic or groups of subatomic particles. Three sorts are recognised alpha, beta and neutrons. These and gamma radiation are termed ionising radiation.
