Well, it turns out that the x-rays and the far-ultraviolet are absorbed by the first molecules that they encounter. These other wavelengths-- the near ultraviolet, the visible, the near-infrared, the far-infrared-- they are not absorbed at that level. They come streaming on through. So...
In elastic scattering, there is no change in energy, where λin = λout (λ: wavelength). In the case of inelastic scattering, energy is absorbed from the electromagnetic wave directed towards the medium, where λin < λout. 2.1.1. Rayleigh Scattering The Mie and Rayleigh theory lies ...
An absorbed thermal X-ray plasma with kT~0.3 keV and Z~0.2 Z◉ was found within Galactic longitude |l| < 20° and latitude 5° < |b| < 60°, covering the entire extent of the Fermi bubbles. However, questions remain, why are the north and south X-ray skies highly asymmetric, ...
Although it is not a classic ‘waste’ in the fact that we do not actively throw it away, the sunscreen we apply to our skin to protect ourselves from the sun’s UV rays eventually comes off our bodies and runs into the water. That can be either when we bathe after using it, go ...
17, 1938 NATURE 1075 y-rays. This large value arises, of course, from the fact that neutron energy, by contrast with y-ray energy, is absorbed to a very much greater extent in material rich in hydrogen than in air. We can find no explanation for the large difference between the two ...
A light-colored, clear cover will allow the sun’s UV rays to pass through to the water, thereby heating it. A dark, opaque cover may still let some through if the material is thin, but not as many as the light, clear cover. To get the most heat transfer from a solar blanket, ...
E1: The X-ray emission from the inner accretion disk of primary BH is initially obscured by a thick reprocessing layer, by which the X-ray radiation is absorbed and re-emitted at UV/optical wavelengths; E2: Ionization radiation results in a change in the opacity at later times, and direct...

A sevenfold integral expression is derived for the absorbed dose rate from the uncollided flux of gamma rays at the center of a spherical shell shield bombarded by an omnidirectional flux spectrum of protons. The general formulation is reduced to a fourfold integral on the basis of simplifying as...
