It is shown that the narrow‐beam attenuation curve can be a functional description of a low‐energy x‐ray beam, as is the spectral distribution. Physical quantities, which are usually calculated by integration over the spectral distribution (differential photon or energy fluence), can also be obtained from the narrow‐beam attenuation curve without any need for an explicit knowledge of the spectral distribution.
