title: Experimental X-ray attenuation coefficients at low photon energies for substances of medical importance.
abstract: Recent experimental values of X-ray mass attenuation coefficients for the elements zota = 6 to zota = 18 in the energy range from 4 to 25 keV suggest improvements to the data set presented in the ICRU Report 17. The results are, however, in excellent agreement with the theoretical data of Storm and Israel (1970). Values of mass attenuation coefficient for these elements and for a selection of materials of medical and biological importance are presented.
