Dose Equivalents for Monoenergetic Positrons Incident on the ICRU Sphere
Dose equivalents per unit fluence at 0.07 mm, 3 mm, 10 mm and maximum dose equivalent per unit fluence along the principal axis of the ICRU sphere have been calculated by the FLUKA Monte Carlo code for a broad parallel beam of monoenergetic positrons incident normal to the surface. Calculations were performed for kinetic energies ranging from 70 keV to 10 GeV. The results are compared with those obtained in the case of electrons. In the energy range where dose equivalents are almost constant, suitable average values are suggested to be used for practical purposes.
