Linear Attenuation Coefficients. Monochromatic photons are attenuated exponentially in a uniform target. The number of photons in a pencil beam interact within a small distance dx is. dN = -μ Ndx. where μ is the linear attenuation coefficient and the solution to the above differential equation is.
Attenuation Coefficients Linear attenuation coefficient µ: The probability of an interaction per unit distance traveled. µ has the dimensions of inverse length (eg. cm-1). N =N e−µx 0 The coefficient µ depends on photon energy and on the material being traversed. Radiation Interactions: photons Page 9 of 13
Linear Attenuation Coefficients. Table of Linear Attenuation Coefficients (in cm-1) for different materials at photon energies of 100, 200, and 500 keV.
The Linear Attenuation Coefficient for Air is the product of the Mass-Attentuation Coefficient of Air and the density of Air. The density of air is 0.001293 g/cm 3
Linear Attenuation Coefficients – Tables. Table of Linear Attenuation Coefficients (in cm-1) for different materials at gamma-ray energies of 100, 200, and 500 keV.
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. [1]
