AW: Effective Photon Energy of X-rays

[Chris Alston <alstonc@odrge.odr.georgetown.edu>]

>a loooong time ago I have been measuring lots of x-ray spectra up to 300
>kVp. The result was a catalogue, which I guess will no longer be
>available (review in Medical Physics 9 (1982) 134-135). One of the side
>effects was a paper entitled "Equivalent half-value thicknesses and mean
>energies of filtered x-ray bremsstrahlung spectra" by W.W.Seelentag and
>W.Panzer (Brit. Journal of Radiology 53 (1980) 236-240). There you'll
>find tables helping you to estimate mean energy from kVp and first HVL
>(just kVp alone is not sufficient to estimate mean energy with any
>satisfactory accuracy).
