Radiography With Scattered Radiation
Health Physics, 1964Seven 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)

Scattered radiation in chest radiography
Medical Physics, 1981Luminance 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).

The absorption of radiation by a molecule and the consequent change of the molecule’s dynamic energy by a discrete amount, as discussed in connection with spectral lines in Chapters 2 and in 3.1, is a resonant and inelastic scattering process: resonant because the photon energy has to fit exactly the energy jump W n − W m of the molecule from a lower ...

Scattering of electromagnetic radiation
2023Abstract In this chapter we discuss the scattering of electromagnetic waves by charged particles. We define the scattering cross-section. We then consider the scattering of electromagnetic waves from free electrons, giving rise to the Thomson cross section, expressed in terms of the classical electron radius.

Radiation Scattering techniques
1986The previous chapter dealt in detail with industrial applications of measurements of gamma-ray absorption for the purposes of determining levels in vessels, thicknesses of materials, density profiles and so on. In the main, these gamma-ray absorption techniques are the simplest and most flexible to employ on industrial plant.

Introduction Electromagnetic radiation can be considered as a stream of photons moving at the speed of light. These photons have no mass and can be treated as waves. There is a spectrum of electromagnetic radiation, ranging from low-energy radiowaves to high energy γ-rays; this spectrum...

The preceding chapters have dealt with radiative heat transfer in nonscattering media only. This assumption is justifiable for many engineering radiative heat transfer calculations where the system under consideration is not to depart arbitrarily far from the non-scattering assumption.
