What is ISO 80000-10 - Quantities and units for atomic and nuclear physics about?
Multiple systems of quantities developed across the world over time. Unified systems can facilitate research and communication within the scientific community, doing away with the need for conversion factors.
ISO 80000 comprises a series of international standards introducing the International System of Quantities (ISQ). The guidelines of the ISO 80000 family of standards specify the use of physical quantities and units of measurement, along with the related formulas and units, in scientific and educational documents.
ISO 80000-10 guides you with names, symbols, definitions, and units for quantities used in atomic and nuclear physics. Where appropriate, conversion factors are also given.
Who is ISO 80000-10 - Quantities and units for atomic and nuclear physics for?
ISO 80000-10 on quantities and units for atomic and nuclear physics has applications for education and research in the fields of:
- Physics
- Chemistry
- Earth science
- Astronomy
- Mathematics
- Technology
- Biology
Why should you use ISO 80000-10 - Quantities and units for atomic and nuclear physics?
Numerical values of physical constants in ISO 80000-10 are quoted in the consistent values of the fundamental physical constants published in CODATA recommended values. The indicated values are the last known before publication.
ISO 80000-10 guides you with definitions based on a differential quotient of the type dA/dB in which the quantity A is of a stochastic nature, a situation common in ionizing radiation metrology.
The guidelines of ISO 80000-10 provide you with required symbols, definitions and units of atomic and nuclear physics for research and educational use.
What’s changed since the last update?
BS EN ISO 80000-10:2019 supersedes ISO 80000-10:2009. BS EN ISO 80000-10:2019 includes some technical and editorial changes with respect to ISO 80000-10:2009. These include:
- The table giving the quantities and units has been simplified
- Some definitions and the remarks have been stated physically more precisely
-
Definitions in this document have been brought in line with their equivalent ones in ICRU 85a
