Abstract

The NPL air kerma primary standard free-air ionisation chamber for medium energy x-ray qualities was established in 1998. The International Commission for Radiation Measurements and Units Report 90 proposes the introduction of two new correction factors applicable to free air ionisation chambers in this energy range. This report summarises all of the factors for the NPL primary standard including the two new factors.
