64Mass attenuation coefficient — The mass attenuation coefficient is a measurement of how strongly a chemical species or substance absorbs or scatters light at a given wavelength, per unit mass. In addition to visible light, mass attenuation coefficients can be defined for other …
65Absorption coefficient — The absorption coefficient α is a property of a material. It defines the extent to which a material absorbs energy, for example that of sound waves or electromagnetic radiation. Wallace Sabine was a pioneer of this concept in acoustics and… …
66Correction for attenuation — is a statistical procedure, due to Spearman (1904), to rid a correlation coefficient from the weakening effect of measurement error (Jensen, 1998), a phenomenon also known as regression dilution. In measurement and statistics, it is also called… …
