Radiation shielding structures

A radiation shielding structural component, comprising in combination

• (a) two longitudinally elongated bodies each having L-shaped cross-section in lateral planes normal to the longitudinal direction,
• (b) each body including a panel shaped core consisting of radiation shielding material, and glass fiber layers surrounding said core and attached thereto in covering relation therewith,
• (c) each body including a filler sheet extending in sandwiched relation to the core and the glass fiber layers, and generally parallel to the core,
• (d) said bodies forming a recess located edgewise between said filler sheets and overlapping portions of the cores closest to said flanges, the recess adapted to receive an auxiliary panel that incorporates an auxiliary core consisting of radiation shielding material, and glass fiber layers at opposite sides of said auxiliary core,
• (e) and including said auxiliary panel in said recess and the auxiliary core of which overlaps said core portions of said bodies, the panel attached to said bodies.
