Sain simuloimalla arvioksi s\u00e4teilyannokselle vesifantomissa (16 \u00b1 2) nGy, joka oli noin nelinkertainen mitattuun tulokseen (4 \u00b1 1) nGy verrattuna. Tulosten v\u00e4linen ero johtuu ensisijaisesti simuloidun geometrian ja r\u00f6ntgenspektrin yksinkertaistuksista. Totesin Geant4:n soveltuvan hyvin s\u00e4teilyannoksen arviointiin monimutkaisten geometrioiden tapauksissa, mik\u00e4li l\u00e4ht\u00f6tiedot ovat saatavilla yksityiskohtaisesti.

The simulated dose in a water phantom (16 \u00b1 2) nGy was approximately fourfold compared to the measured value (4 \u00b1 1) nGy. The difference is mainly due to the simplified models of room geometry and x-ray spectrum.
