In biochemistry, the molar attenuation coefficient of a protein at depends almost exclusively on the number of aromatic residues, particularly tryptophan, and can be predicted from the sequence of amino acids.

Tables of photon "'mass attenuation coefficients "'are essential in radiological physics, radiography ( for medical and security purposes ), dosimetry, diffraction, interferometry, crystallography and other branches of physics.
23.
A method for establishing attenuation coefficients with which actual HU values can be derived from CBCT HU values was published in 2010 and further research is currently under way to perfect this method " in vivo ".
24.
I _ o is the initial intensity of the beam, \ alpha is the attenuation coefficient ( in units of inverse length ), and z is distance traveled through the attenuating medium ( e . g . tissue ).
25.
When the wave propagates in inhomogeneous seismic media the propagation constant k must be a complex value that includes not only an imaginary part, the frequency-dependent attenuation coefficient, but also a real part, the dispersive wavenumber.

27.
Where \ theta _ i is the transmission angle in the " i " th layer, from Snell's law, \ Delta z _ i is the layer thickness and \ alpha _ i is the attenuation coefficient:
28.
In this use, " opacity " is another term for the mass attenuation coefficient ( or, depending on context, mass absorption coefficient, the difference is described here ) \ kappa _ \ nu at a particular frequency \ nu of electromagnetic radiation.

"' Attenuation coefficient "'or "'narrow beam attenuation coefficient "'of the volume of a material characterizes how easily it can be penetrated by a beam of light, sound, particles, or other energy or matter.
