SUMMARY

The conversion from linear absorption coefficient to mass absorption coefficient for lead involves using the formula: mass absorption coefficient (μ/ρ) = linear absorption coefficient (μ) / density (ρ). The linear absorption coefficient is expressed in inverse centimeters (1/cm), while the mass absorption coefficient is expressed in grams per square centimeter (cm²/g). Understanding the relationship between these coefficients is crucial, especially in contexts like Compton scattering and high-energy photon interactions.

PREREQUISITES
  • Understanding of linear absorption coefficient and its units (1/cm)
  • Knowledge of mass absorption coefficient and its units (cm²/g)
  • Familiarity with the density of lead (11.34 g/cm³)
  • Basic concepts of photon interactions, including Compton scattering
NEXT STEPS
  • Research the formula for converting linear absorption coefficients to mass absorption coefficients
  • Explore the implications of Compton scattering on photon energy and attenuation
  • Study the effects of high-energy photon interactions on matter
  • Examine the role of atomic cross sections in radiation physics
USEFUL FOR

Physicists, materials scientists, and engineers involved in radiation shielding, medical imaging, or any field requiring knowledge of photon interactions with matter.

How do I calculate the mass absorption coeficient ao lead given the linear absorption coeficient and the density of lead.Which formula do I use in this case??.
 
Physics news on Phys.org
The atomic cross section is often measured in cm-squared per atom, the linear absorption coefficient is in inverse cm per 1/e attenuation, and the mass attenuation coefficient is in grams per cm-squared to 1/e. In Compton scattering, there is another: Energy attenuation coefficient, because primary photons create scattered photons of lower energy and additional penetration. Also, at very high energies, photons create high energy showers comprised mainly of electron, positrons, and photons (plus pions, etc.)
 
was that an answer to OP's question?

to OP:

you want to go from units 1/cm to cm^2/g, any suggestions?
