Photoelectric mass attenuation coefficient data

[Orlando]

Homework Statement

I see graphs for the total mass attenuation coefficient such as this all over the web:http://scientificsentence.net/Radiations/images/attenuation_coefficients.jpg
However, I can't find data on the individual attenuation coefficients such as the photoelectric or Compton attenuation coefficients. What I need is either a general formula to find them, although I imagine that the formulas will be very complex, or just experimental data on the coefficients for different elements/mediums (e.g. soft tissue).

2. The attempt at a solution
http://physics.nist.gov/PhysRefData/XrayMassCoef/ComTab/tissue.html
This is the closest data I could find, but it tells me nothing about the individual attenuation coefficients.

Please tell me that someone reading this knows where to find this information or what to Google because I have run out of ideas. Thank you in advance.

Try this doc:

http://www.nist.gov/data/nsrds/NSRDS-NBS29.pdf

It's a collection of photon data tables (cross-sections, attenuation coefficients, etc.) for elements and compounds (Hubbell NSRDS-NBS29) - oldie but goodie :)
