Abstract

X-ray beam spectra varying from conditions approximating those found in mammographic studies to conditions for general purpose diagnostic radiography were obtained for the primary beam as well as for radiation scattered by a radiographic subject. The transmission spectra of various intensifying screens also were measured for these conditions. From the latter it was possible to determine phosphor absorption as a function of x-ray beam quality. The lanthanide phosphors were shown to be less sensitive to scattered radiation than CaW0₄, BaSrSO₄ or Y₂0₂S.
