A Microdosimetric Algorithm for Electron Point Kernel Data: 1. Monoenergetic-Electron Sources

A microdosimetric approach has been used to produce monoenergetic electron point kernel data in the form of probability density functions of specific energy z. These probability density functions are calculated using a 1 µm diameter sphere target to simulate microscopic size receptors. Electron transport is simulated using the Monte Carlo code OREC (Oak Ridge Electron-transport Code). Electron dose point kernel data produced in this study, f(z;r,E,N), are given as functions of source-to-target distance r, initial electron energy E, and the number of electron emissions N. Good agreement is observed between mean specific energies, z, from the probability density functions and absorbed dose values, D, from conventional point kernel data.
