Photon Cross Section Data

Total attenuation (with coherent scatter) of photons for NaI and SiO2, given in cm^2/g. Data taken from the NIST XCOM Photon Cross Section Database.

Format

A list with two elements (data.frames) with two columns (energy_MeV, attenuation_cm2g):

	$NaI
Total attenuation for sodium iodide
$SiO2	Total attenuation for silicon dioxide
