Augustine, R J

For absorbed- dose computation or optimum- shielding determination, it is necessary to know the energy spectrum of stray x radiation. Stray radiation includes scattered, secondary, and leakage radiation. The objective of this investigation is to provide the spectral data on stray x radiation for a variety of experimental conditions. The energy spectra, measured with an x-ray scintillation spectrometer, and percentage roentgen dose rates are presented for the stray radiation from a human-equivalent phantom, from typical radiographic room wall sections, and from the x-ray tube housing. The primary beam spectra are presented also and compared with the stray radiation. Although the most important results of the study are the spectral data, some general conclusions are drawn regarding the quality and quantity of stray radiation. These conclusions indicate the effect of tube voltage, filtration, scatter angle, and wall composition on the spectral distribution and intensity of stray x radiation. In many cases, the quality of the stray radiation is found to be appreciably different than the quality of the primary x-ray beam. (Dissertation Abstr.)
