Radiation exposure of the public due to the emission of airborne radioactivity from the Medical University of Hannover

Based on the interim regulation of the paragraph 117 (16) Radiation Protection Law [1] the radiation exposure to persons in the surroundings and the area of the Medical University of Hannover (MHH) was calculated using the administrative regulation (AVV) [2] to paragraph 45 of the old Radiation Protection Law [3]. First the radiation exposure due to the emissions of airborne radioactivity from MHH-facilities - not including the MHH-TRIGA-reactor - was calculated at selected points in the area and the surroundings of the MHH. Secondly, for the calculation of the radiation exposure caused by the dismantling of the TRIGA-reactor, dose coefficients for several nuclides and selected points were determined. (orig.)
