Various Elemental Effects
Results Using a Mo X-Ray generator:
Zirconium - Absorbs Bremsstrahlung & K-Beta.
Iron - Absorbs the entire spectra.
Molybdenum - Absorbs Bremsstrahlung - Leaving K-Beta & K-Alpha.
Aluminium - 'Pinches' Bremsstrahlung* & Removes 3rd Generation peaks.
Silver - Same as Aluminium, But to greater extent.
Indium - Same as Iron, But to lesser extent.
Copper - Same as Aluminium, Leaving only 1st Generation Peaks.
- - Bremsstrahlung pinching is due to the atomic mass. The denser the atom, the higher the X-Ray Absorption. Only the higher energy X-Rays pass through the filter, appearing as if the Bremsstrahlung continuum had been pinched.
- - In this case, Mo appears to leave K-Alpha and K-Beta alone while absorbing the Bremsstrahlung. This is due to Mo absorbing all of the spectra's energy, but in doing so produces the same characteristic peaks as generated by the target.

Famous quotes containing the words elemental and/or effects:
“But the lightning which explodes and fashions planets, maker of planets and suns, is in him. On one side elemental order, sandstone and granite, rock-ledges, peat-bog, forest, sea and shore; and on the other part, thought, the spirit which composes and decomposes nature,—here they are, side by side, god and devil, mind and matter, king and conspirator, belt and spasm, riding peacefully together in the eye and brain of every man.”
—Ralph Waldo Emerson (1803–1882)
“Like the effects of industrial pollution ... the AIDS crisis is evidence of a world in which nothing important is regional, local, limited; in which everything that can circulate does, and every problem is, or is destined to become, worldwide.”
—Susan Sontag (b. 1933)
