Students are advised to visit the following site
http://physics.nist.gov/PhysRefData/Xcom/html/xcom1.html The following page should be
seen. Then click on submit information. Then try to obtain the graph between the total
linear attenuation coefficient and the photon energy of at least 3 elements/compounds
In this database, it is possible to obtain photon cross section data for a single element, compound, or mixture (a combination of elements and compounds). Please fill out the following information:
Method of entering additional energies: (optional)
Enter additional energies by hand
Total Attenuation with Coherent Scattering
Energies must be between 0.001 - 100000 MeV (1 keV - 100 GeV) (only 4 significant figures will be used).
One energy per line. Blank lines will be ignored
Total Attenuation without Coherent Scattering
Coherent Scattering
Incoherent Scattering
Photoelectric Absorption
Pair Production in Nuclear Field
Pair Production in Electron Field
