FIELD: nuclear physics; protective devices.
SUBSTANCE: invention relates to the field of nuclear power engineering and can be used to protect personnel from radioactive radiation during transport-technological operations during overload with the use of loading and unloading machines (LUM). Biological protection container for the LUM contains a hermetic casing made in the form of a hermetically sealed cylindrical shell with massive flanges, and a biological protection casing fixed to a sealed casing. Body of biological protection is made in the form of a set of elongated wedge-shaped prismatic petals installed parallel to the generatrix of the hermetic body, cross section of each lobe is the shape of an elongated quadrilateral, where its large sides form directions that allow the tabs to be installed back to back with respect to the side surface of an imaginary cylinder covering the maximum area of the source of ionizing radiation.
EFFECT: invention makes it possible to eliminate the penetration of radioactive radiation in the places where the elements fixed on the hermetic housing are docked.
