Modeling, simulation and measurement of radiation exposure using electronic personal dosimeters on realistic and ICRU phantoms

Abstract
Exposure studies with voxel phantoms were carried out to understand the new personal dose measurand Hp(10) measured by personal dosimeters under realistic wearing conditions. Two simulated realistic voxel phantoms and the dosimeter assembly are described in a first step. Conditions such as photon fluence, radiation field geometry, and photon energy for simulating the external photon fields at the realistic model are specified. Person-related effective doses are calculated to evaluate the personal dose. The relation between measured deep personal dose and effective dose is demonstrated and discussed by means of the simulated response function of the dosimeters at realistic phantoms.
Abstract
Zum Verständnis der mit Personendosimetern gemessenen neuen Personendosismessgröße Hp(10) unter realistischen Tragebedingungenen wurden Expositionsstudien mit Hilfe von Voxel-Phantomen durchgeführt. In einem ersten Schritt werden zwei simulierte realistische Voxel-Phantome und die Dosimeteranordnung an den Phantomen beschrieben. Bedingungen wie die Photonenfluenzen, Bestrahlungsgeometrien und Photonenenergien zur Simulation der externen Photonenfelder am realistischen Modell werden im Detail beschrieben. Zur Bewertung der Personendosis werden die entsprechenden Effektivdosen berechnet. Der Zusammenhang zwischen gemessener Tiefenpersonendosis und der effektiven Dosis wird anhand des simulierten Ansprechvermögens der Dosimeter an den realistischen Phantom dargestellt und diskutiert.
