Radiation exposure due to gamma-ray submersion
Description
The report explains the development of the mathematical foundations for calculation of the dispersion factors of gamma-ray submersion, and the calculations. The Gaussian model describing the dispersion quasi like a molecular diffusion is one of the starting points, the other is the point-kernel model for the transport of gamma rays, with radiation transport being treated as quasi optical, and build-up factors being used for describing the impact of interaction between gamma radiation and matter. The time-space continuum integration was to be done for calculation of the dispersion factor. The time integration was done first, and for the remaining space integration, the convergence problems were solved. (orig./HP)

Die mathematischen Grundlagen fuer die Berechnung des Ausbreitungsfaktors der γ-Submersion wurden entwickelt und die Berechnungen durchgefuehrt. Ausgangspunkt ist einmal das Gauss-Modell, in dem die Ausbreitung quasi wie eine molekulare Diffusion beschrieben wird. Zum anderen das Point-Kernel-Modell fuer den Transport der γ-Strahlung, wo die Strahlung als quasi optisch behandelt wird und der Einfluss der Wechselwirkung der γ-Strahlung mit der Materie durch Aufbaufaktoren beschrieben wird. Zur Berechnung des Ausbreitungsfaktors war ueber das Raum-Zeit-Kontinuum zu integrieren. Die Zeitintegration konnte dabei vorweg durchgefuehrt werden. Fuer die verbleibende Raumintegration wurden die Konvergenzprobleme geloest. (orig./HP)
