Implementation and characterization of a virtual Cs-137 gamma irradiation facility — •Lena Olbrich1, Evelin Derugin1, Kevin Kröninger1, Florian Mentzel1, Jörg Walbersloh2, and Jens Weingarten1 — 1TU Dortmund — 2Materialprüfungsamt NRW
A Cs-137 gamma irradiation facility is operated at the Materialprüfungsamt NRW for research purposes in the field of thermoluminescence dosimetry and calibration of dosimeters, mainly for official personal dose monitoring. The facility is sufficiently characterized for routine dose monitoring. For the development of new dosimeters, a complete simulation of the irradiation facility is useful to perform virtual prototype tests before anything is built. To understand all the processes involved and their influence on the radiation field at different points, e.g. in the reference point for calibration, all relevant aspects of the entire irradiation facility are implemented and investigated successively using Geant4 simulations.
In this talk, the results of the implementation and characterization of a virtual Cs-137 irradiation facility will be presented.
