Fluence to Dose Conversion Coefficients for Electrons up to 200 MeV in Localized Exposure

To estimate radiation hazards in the accidental exposure to energetic electrons, effective doses were calculated with the EGS4 Monte Carlo simulation code and the MIRD-5 human phantom for high energy electron beams like those from a LINAC in which non-uniform exposure of the human body would occur. The calculations show that the effective doses depend on the incident electron energy and beam size and on the place of the exposure of the body.
