Abstract :
The impact of high energy electrons in multi-layered shielding structures has been measured in terms of dose enhancement effects. New dosimetric data from a series of extensive experimental tests have been obtained and compared to the latest electromagnetic physics models included in the Geant4 Monte Carlo toolkit.
