CSN EN IEC 60806 ed. 2

CSN EN IEC 60806 ed. 2 This document is applicable to x-ray source assemblies and x-ray tube assemblies. This document specifies a method for the determination of the greatest geometrically symmetrical radiation field at a specified distance from the focal spot for which the percentage air kerma rate along the major axes of the radiation field does not fall below a permitted value. In case multiple focal spots are not super-imposed, each focal spot has its own reference axis. Then the maximum radiation field can be given for each focal spot separately.
