摘要：The present invention relates to a radiation protection structure for beamguiding devices (28) of a particle accelerator and / or irradiation locations to a particleaccelerator, comprising:a load bearing building (23) with concrete walls as the side walls(14, 16), ceilings (18) and / or floors (10), wherein the concrete walls, a first radiation -baffle layer form,a second radiation - baffle layer (20) from a loose or compacted fillingcompound, in particular ground, on the outside of at least some of the concrete walls,whereby the molded part content is to be water-permeable in a certain extent, so thatradionuclides from the filling compound would be washing away mbar, wherein theconcrete walls and the second radiation - baffle layer (20) from the loose or compactedfiller an at least two-layer radiation shielding arrangement form,a sealing foil (24) for thesecond radiation - baffle layer (20), wherein the sealing foil (24) the second radiation -baffle layer (20) from the loose or compacted filler material on the outside of the secondradiation - baffle layer (20) and, wherein the loose or compacted molded part content ofthe second radiation - baffle layer (20) between the concrete walls and of the sealing foil(24) is enclosed impermeable to water and thus the filling compound hydro geologicallyis immobilized.
