Scattering of Radiation by Particles [PDF]

, 1981
When electromagnetic radiation falls on a single particle it may be deflected or absorbed. In the geometrical optics limit the deflection is considered to arise from reflection and refraction, and diffraction on the cross-sectional area. In the wave optics analysis the interpretation is not so simple, but the deflection process is referred to as ...

Radiography With Scattered Radiation

Health Physics, 1964
Seven radiographs of the oral region of a manikin were produced simultaneously by lead-walled pinhole cameras. Scattered radiation, originating mainly in the tongue, was used to produce the radiographs. The tongue was irradiated by a beam of x rays directed vertically through the floor of the mouth. (auth)

The Intensity of Scattered Radiation in Mammography

Radiology, 1978
The ratio of scattered-to-primary radiation has been measured for a range of x-ray tube voltages, field sizes and phantom thicknesses that typify clinical mammographic situations. The relative intensity of scattered radiation measured was essentially independent of kVp but increased as the phantom thickness and radiation field size increased.

Dosimetry of Scattered Radiation to the Fetus

JAMA: The Journal of the American Medical Association, 1969
Measurement of scattered radiation to the fetus during radiation therapy for Hodgkin's disease of the mediastinum was 0.0026 rads per rad given to the tumor, or 7.9 rads for 14 treatments or 3,500 rads. Measurements of scattered radiation made on a phantom for three different modalities indicate the scattered dose to a fetus would be 3.5 to 14 rads in ...

Scattered radiation in chest radiography

Medical Physics, 1981
Luminance scatter fractions were measured for patients and phantoms in various regions of the chest film. Scatter fractions were found to be highly variable, being quite high in the regions of the chest with a large equivalent tissue thickness (e.g. mediastinum, chest wall, and subdiaphramatic areas).
