Which is also known as nuclear reaction. Modern nuclear chemistry also referred to as radio chemistry, has become high knowledge base in its applications,\u00a0 from the study of element formation in space to the design of radio pharmaceuticals for diagnostic medicine. In fact, the chemical technology developed by these chemists has become so important that geologists, \u00a0biologists and physicists are using nuclear chemistry as a common tool in their fields.<\/p>\n<p>Nuclear chemists can be seen\u00a0in a variety of research applications, like\u00a0nuclear imaging and nuclear technology. The\u00a0chemists usually\u00a0work to improve the efficiency and safety of nuclear energy sources and the way radioactive materials are disposed of\u00a0and stored.<\/p>\n<p>Nuclear chemists carry out applied research,\u00a0basic research\u00a0and\u00a0theoretical research. They\u00a0often work in the labs and are\u00a0responsible for the operation, maintenance, and repair of state-of-the-art equipment. They are also responsible for the maintenance of sample preparation materials and equipment, and for the safe use and disposal of samples and other substances\u00a0used in the lab.<\/p>\n<p>Marie Curie, who was the founder of nuclear chemistry, was along with\u00a0Antoine Henri Bekrel&#8217;s found that photographic film can give out\u00a0light that can be exposed even when uranium\u00a0minerals are covered\u00a0in black paper. Using an electrometer which was used to\u00a0measure the electrical conductivity of air (the predecessor of the Geiger counter) which was invented by her husband Pierre and his younger brother Jack, Curie\u00a0was able to prove that thorium also produces these rays.

These nuclear changes are a source of radioactivity,\u00a0and nuclear power. The energy produced\u00a0from the nuclear reactions has tremendous\u00a0applications. Nuclear chemistry is also termed radiochemistry, which is\u00a0the study of the elements composing the universe, design, and development of radioactive drugs for medicinal uses, and many other scientific applications.<\/p>\n<h3><strong><b>Nuclear Radiations<\/b><\/strong><\/h3>\n<p>Nuclear radiation is\u00a0the photons and particles that are generated during nuclear reactions. The particles emitted in nuclear reactions have\u00a0an energy that is huge\u00a0enough to knock electrons from atoms and molecules, causing them to \u00a0ionize. Hence, nuclear radiation is also referred\u00a0to\u00a0as ionizing radiation.<\/p>\n<p>Nuclear radiations consists of\u00a0alpha rays, beta rays, and gamma rays. Nuclear reactions give out\u00a0ionizing subatomic particles, like\u00a0muons, positrons,\u00a0alpha particles, neutrons, beta particles, mesons and cosmic rays. For example: during the fission reaction of Uranium-235 , the nuclear radiation that is emitted has\u00a0gamma-ray\u00a0along with\u00a0photons and neutrons.<strong><b>\u00a0<\/b><\/strong><\/p>\n<h3><strong><b>Types of Radiations<\/b><\/strong><\/h3>\n<h4><strong><b>Alpha Radiation:<\/b><\/strong><\/h4>\n<p>Alpha rays are dense\u00a0particles and have a very little range, so they don&#8217;t very\u00a0far. This means that these\u00a0particles cannot penetrate even a piece of paper. Alpha particles outside the body cannot\u00a0even pass through the skin\u00a0surface of a human body. However, inhaling or ingesting substances that emit alpha particles can expose vulnerable\u00a0tissues like\u00a0that to the lungs. Hence, high-level radon in your home is considered a problem\u00a0for this reason.<\/p>\n<p>Alpha radiation is the release\u00a0of alpha particles when an atom\u00a0goes through radioactive decay. An alpha particle consists of 2\u00a0protons and 2\u00a0neutrons and is same as the Helium-4 atom. Thus, the resulting element has an atomic number less by 2\u00a0units and an atomic mass less by 4units than that of the originating element. Example: Uranium-238 undergoes alpha decay in the manner shown in the following equation:<\/p>\n<p><sup>238<\/sup><sub>92<\/sub>U \u2192 <sup>234<\/sup><sub>90<\/sub>Th + <sup>4<\/sup><sub>2<\/sub>He<\/p>\n<h4><strong><b>Beta Radiation:<\/b><\/strong><\/h4>\n<p>Beta particles can travel a little\u00a0more than alpha particles. You can use a relatively smaller\u00a0protective covering to stop them. They can get into human\u00a0body, but they can&#8217;t penetrate through it completely. To make use of beta particles in\u00a0medical imaging, \u00a0they must be released through substances injected into the body. If radioactive substances can be introduced into tumors, beta particles will also be used in treating cancer.<\/p>\n<p>Beta radiations contains\u00a0stream of high-speed electrons. Beta-decay are\u00a0of 2\u00a0types \u2013beta plus and beta minus. In beta plus decay, the nucleus emits a positively charged electron (positron) and a proton that is regenerated\u00a0into a neutron (neutrino). In beta minus decay, the nucleus gives out\u00a0a neutron that is changed\u00a0into a proton (antineutrino) and an electron.<\/p>\n<p>Beta minus decay: <sup>1<\/sup>n \u2192 <sup>1<\/sup>p<sup>+ <\/sup>+ <sup>0<\/sup><sub>-1<\/sub>\u03b2<sup>&#8211;<\/sup>\u00a0+ v\u0305<\/p>\n<p>Beta plus decay: <sup>1<\/sup><sub>1<\/sub>p<sup>+<\/sup>\u00a0\u2192 <sup>1<\/sup><sub>0<\/sub>n + <sup>0<\/sup><sub>1<\/sub>\u03b2 + v<\/p>\n<p><sup>12<\/sup><sub>7<\/sub>N \u27f6 <sub>6<\/sub><sup>12<\/sup>C + <sup>0<\/sup><sub>1<\/sub>\u03b2<sup>+<\/sup><\/p>\n<p><sup>14<\/sup><sub>6<\/sub>C \u27f6 <sup>14<\/sup><sub>7<\/sub>N + <sup>0<\/sup><sub>-1<\/sub>\u03b2<\/p>\n<h4><strong><b>Gamma Radiation:<\/b><\/strong><\/h4>\n<p>Gamma rays and X-rays are highly penetrating EM or electromagnetic radiation that can go in\u00a0through the body. They are proven to be useful in a medicine-to find\u00a0if the bones are broken, where the cavities are, or to identify a\u00a0tumor. Shields made of high-density substances\u00a0such as concrete and lead are used to avoid exposure to sensitive internal organs and those who may have to handle this type of radiation.<\/p>\n<p>Gamma radiation (\u03b3) does not have\u00a0any particles. Instead, it consists of\u00a0photons of energy being generated\u00a0from an unstable radioactive nucleus. Gamma rays are electromagnetic emissions\u00a0of short wavelengths and have no charge or mass. These rays represent the loss in energy while\u00a0the\u00a0rest of the nucleons undergo stable rearrangements, and thus, gamma rays come with\u00a0other radioactive emissions.

Fission was discovered by stuffing\u00a0a sample of Uranium-235 with neutrons, which resulted in the formation\u00a0of lighter elements like Barium. In a distinctive nuclear chain reaction, each dividing nucleus releases more than\u00a0a single neutron, which, in turn, clashes\u00a0with neighboring nuclei and induces a succession of self-sustaining nuclear fission reactions. The fission rate escalates\u00a0geometrically with each generation of events.<\/p>\n<h3><strong><b>Nuclear Fusion<\/b><\/strong><\/h3>\n<p>Nuclear Fusion is a simulated nuclear reaction in which two or more nuclei of elements combine to produce a heavier and more stable nucleus. The initiation of the fusion process needs\u00a0very high temperatures, which are got\u00a0from nuclear fission reactions. Nuclear Fusion generates explosive amounts of energy, which is the source of power for the sun and all the stars.
