This app provides photon mass attenuation coefficients by photon energy for 100 elements and 196 materials.
Most element attenuation coefficients are from ICRU Report 33 (1980), Radiation Quantities and Units. The composition data of common used materials used for calculating attenuation coefficients are from ICRU Report 44 (1989), Tissue Substitutes in Radiation Dosimetry and Measurement.
