Fluence to effective dose conversion coefficients calculated for monoenergetic electrons up to 200 MeV in partial exposure geometries.
Organ doses and effective doses were calculated for monoenergetic electrons from 0.1 to 200 MeV using the EGS4 Monte Carlo simulation code and the MIRD-5 human phantom in various non-uniform exposure geometries: anterior-posterior (AP) and posterior-anterior (PA). Below 1 MeV, the skin is the main contributor to the effective dose conversion coefficients for each exposure geometry; however, above 1 MeV the calculations showed that the effective doses of partial exposures depended on the incident electron energy, the place and the size of the exposure on the body.
