Results for neutrons have lower errors but are The shielding are typically very high ( > 90 %) which suggests there is I should also point out that the errors on the gamma dose rates outside Is my choice of biasing which is leading to these fluctuations, canĪnyone suggest how I might improve it to obtain 'better' results outside Shield wall occasionally) or are they artefacts of the biasing ? If it That you would expect to measure doses of this magnitude outside the My question is therefore, are these high results in any way 'real' (in In this region where I am scoring up to 2 E-10 microSv per electron. Wall) are 1 E-12 microSv per electron or less. Region to the furthest left hand side of the plot, up to the grey shield The majority of doses outside the beamline shielding (the The attached plot from SimpleGeo shows a plan view of the geometry with
Through this list, I have used the EMF-BIAS option to apply biasingĮverywhere, including in the scoring regions. The beamline shield wall at an electron accelerator. I have been using Fluka to calculate gamma and neutron doses outside
