Question

WHAT IS NUCLEAR FUSSION, NUCLEAR FISSION, RADIOACTIVITY, ALPHA, BETA AND GAMMA RADIATIONS???????????????

Answer 1

Radiation-In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. Nuclear Fusion-a nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy Nuclear Fission-a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy. Radioactivity-the emission of ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei Beta is a historical measure of volatility. Beta measures how an asset (i.e. a stock, an ETF, or portfolio) moves versus a benchmark (i.e. an index). Alpha is a historical measure of an asset's return on investment compared to the risk adjusted expected return. Gamma rays-Gamma ray (also called gamma radiation), denoted by the lower-case Greek letter gamma (γ or γ \gamma ), is penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei and consists of high-energy photons. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays. Rutherford had previously discovered two other types of radioactive decay, which he named alpha and beta rays.
