# Kerma definition

Kerma means the quantity defined by the International Commission on Radiation Units and Measurements. The kerma, K, is the quotient of dEtr by dm, where dEtr is the sum of the initial kinetic energies of all the charged particles liberated by uncharged particles in a mass dm of material; thus K=dEtr/dm, in units of J/kg, where the special name for the unit of kerma is gray (Gy). When the material is air, the quantity is referred to as "air kerma."
Kerma means the sum of the initial energies of all the charged particles liberated by uncharged ionizing particles in a material of given mass.
Kerma means the sum of the ini- tial energies of all the charged par- ticles liberated by uncharged ionizing particles in a material of given mass.

## Examples of Kerma in a sentence

## More Definitions of Kerma

Kerma. (K [italicized]) means kinetic energy released in a unit mass, determined by the quotient K = dEtr / dm, where dEtr is the sum of the initial kinetic energies of all the charged ionizing particles (such as electrons) liberated (transferred, Etr) by uncharged ionizing particles (such as neutrons and photons) in air of mass dm. Kerma is measured in joules per kilogram (J/kg).
