Webb17 sep. 2009 · Abstract. Tables and graphs of the photon mass attenuation coefficient μ / ρ and the mass energy-absorption coefficient μen / ρ are presented for all of the elements Z = 1 to 92, and for 48 compounds and mixtures of radiological interest. The tables cover energies of the photon (x-ray, gamma ray, bremsstrahlung) from 1 keV to 20 MeV.

The amount of contaminant absorbed represents what is available for interaction with target tissues or organs. WebbOptical properties of human skin in the near infrared wavelength range of 1000 to 2200 nm. In this paper we present the absorption coefficient mu(a) and the isotropic scattering coefficient mu(s)(') for 22 human skin samples measured using a double integrating sphere apparatus in the wavelength range of 1000-2200 nm. chords i give myself away
