Abstract
A direct comparison was made between the air kerma primary standards used f or the measurements of low-energy x rays at the National Institute of Stand ards and Technology (NIST) and the National Physical Laboratory (NPL). The comparison was conducted at the NPL using NPL reference radiation qualities between 10 kV and 80 kV. The results show the primary air-kerma standards to agree within 0.6 % of their values for beam qualities up to 80 kV.
