WebbHenri Becquerel. Antoine Henri Becquerel ( / ˌbɛkəˈrɛl /; [3] 15 December 1852 – 25 August 1908) was a French engineer, physicist, Nobel laureate, and the first person to discover evidence of radioactivity. For work in this field he, along with Marie Skłodowska-Curie and Pierre Curie, [4] received the 1903 Nobel Prize in Physics. WebbHalf-life (symbol t ½) is the time required for a quantity (of substance) to reduce to half of its initial value.The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive. The term is also used more generally to characterize any type of exponential (or, rarely, non …

Theory of radioactivity

WebbThe relativity variation of mass with velocity is taken into account without difficulty. The underlying ideas of the theory are very simple. Consider an atom interacting with a field of radiation, which we may suppose for definiteness to be confined in an enclosure so as to have only a discrete set of degrees of freedom. WebbTheory of Alpha Decay – Quantum Tunneling Alpha decay (or α-decay and alpha radioactivity) represents the disintegration of a parent nucleus to a daughter through the emission of the nucleus of a helium atom. This transition can be characterized as: As can be seen from the figure, the alpha particle is emitted in alpha decay.

Webb8 aug. 2024 · There are three main forms of radioactive emissions. The first is called an alpha particle ,which is symbolized by the Greek letter α. An alpha particle is composed of two protons and two neutrons, and so it is the same as a helium nucleus. (We often use He 2 4 to represent an alpha particle.) It has a 2+ charge.
