The curie (symbol Ci) is a non-SI unit of radioactivity originally defined in 1910. According to a notice in Nature at the time, it was to be named in honour of Pierre Curie , [ 1 ] but was considered at least by some to be in honour of Marie Curie as well, [ 2 ] and is in later literature considered to be named for both.
The becquerel (/ ˌ b ɛ k ə ˈ r ɛ l /; symbol: Bq) is the unit of radioactivity in the International System of Units (SI). One becquerel is defined as an activity of one decay per second . For applications relating to human health this is a small quantity, [ 1 ] and SI multiples of the unit are commonly used.
Specific activity. Specific activity (symbol a) is the activity per unit mass of a radionuclide and is a physical property of that radionuclide. [1][2] It is usually given in units of becquerel per kilogram (Bq/kg), but another commonly used unit of specific activity is the curie per gram (Ci/g). In the context of radioactivity, activity or ...
10 6 s −1. The rutherford (symbol Rd) is a non-SI unit of radioactive decay. It is defined as the activity of a quantity of radioactive material in which one million nuclei decay per second. It is therefore equivalent to one megabecquerel, and one becquerel equals one microrutherford. One rutherford is equivalent to 2.703 × 10 −5 curie .
Counts per minute (abbreviated to cpm) is a measure of the detection rate of ionization events per minute. Counts are only manifested in the reading of the measuring instrument, and are not an absolute measure of the strength of the source of radiation. Whilst an instrument will display a rate of cpm, it does not have to detect counts for one ...
Piece of code from a module of the Linux kernel, which uses snake case for identifiers. Snake case (sometimes stylized autologically as snake_case) is the naming convention in which each space is replaced with an underscore (_) character, and words are written in lowercase. It is a commonly used naming convention in computing, for example for ...
Antoine Henri Becquerel (/ ˌbɛkəˈrɛl /; [3] French: [ɑ̃twan ɑ̃ʁi bɛkʁɛl]; 15 December 1852 – 25 August 1908) was a French engineer, physicist, Nobel laureate, and the first person to discover radioactivity. For work in this field he, along with Marie Skłodowska-Curie and Pierre Curie, [4] received the 1903 Nobel Prize in Physics.
Serpent (software) Serpent is a continuous-energy multi-purpose three-dimensional Monte Carlo particle transport code. It is under development at VTT Technical Research Centre of Finland since 2004. [1] Serpent was originally known as Probabilistic Scattering Game (PSG) from 2004 to the first pre-release of Serpent 1 in October 2008. [2]
