The SI unit of mass attenuation coefficient is the square metre per kilogram (m2/kg). Other common units include cm 2 /g (the most common unit for X-ray mass attenuation coefficients) and mL⋅g −1 ⋅cm −1 (sometimes used in solution chemistry). Mass extinction coefficient is an old term for this quantity.

Attenuation of radiation Attenuation of X rays is not linear but exponential. Attenuering (försvagning) av strålning Attenueringen av röntgenstrålning är inte linjär 

This operation  Linear attenuation coefficient (µ) is a constant that describes the fraction of attenuated incident photons in a monoenergetic beam per unit thickness of a material 1. It includes all possible interactions including coherent scatter, Compton scatter and photoelectric effect 1. Its complement is the transmitted portion of the beam. The linear attenuation coefficient, attenuation coefficient, or narrow-beam attenuation coefficient characterizes how easily a volume of material can be penetrated by a beam of light, sound, particles, or other energy or matter. The linear attenuation coefficient increases as the atomic number of the absorber increases. The linear attenuation coefficient for all materials decreases with the energy of the gamma rays. We hope, this article, Linear Attenuation Coefficient, helps you.

The linear attenuation coefficient database developed above is a practical, user friendly tool for calculating linear attenuation coefficients. It is also very flexible in that it allows the user to calculate attenuation coefficients at any effective X-ray energy between 41.7 keV and 74.6 keV and this can be done offline. ABSTRACT: Linear attenuation coefficient (𝜇) is a measure of the ability of a medium to diffuse and absorb radiation. In the interaction of radiation with matter, the linear absorption coefficient plays an important role because during the passage of radiation through a medium, its absorption depends on the wavelength of the Linear Attenuation Coefficient: When a monochromatic x-ray beam passes through an absorbing medium, the transmit-ted intensity, I, obeys Beer’s law, so that (6) where I 0 is the incident x-ray intensity, µ(s) the linear attenua-tion coefficient at a distance (s) into the specimen and z the thickness. For a single-phase specimen composed of n differ- 2007-05-15 · The linear attenuation coefficient, also called the narrow beam attenuation coefficient, is a quantity which describes the extent to which the intensity of energy beam is reduced as it passes 2021-03-16 · The x-ray linear attenuation coefficients (calculated using published data) and the BSE coefficients (calculated using Monte Carlo simulation) were compared for samples of various phase proportions. It was found that the BSE coefficient correlated only with the x-ray attenuation coefficient for samples with PMMA infiltration. The mass attenuation coefficient ([ [mu].sub.m]/ [rho]) can be obtained by dividing the linear attenuation coefficient of the material ([ [mu].sub.m]) by its density ([rho]).
