Reference Air Kerma Rate K

Air Kerma Strength S

The “Strength” of a Source

The quantity of preference to specify the

source strength would be the “absorbed dose to

water at a specified distance in a full water

geometry” (as it is the case for ERT). This is,

however, until now not achievable in practice.

Currently the dosimetry systems (e.g. Well Type

Chambers) are calibrated at least for Reference Air

Kerma Rate K

or equivalently for Air Kerma Strength
