COMPOSITE BIOLOGICAL PROTECTION OF NUCLEAR AND (OR) RADIATION DANGEROUS FACILITY Russian patent published in 2012 - IPC G21F3/04 

FIELD: power industry.

SUBSTANCE: composite biological protection against ionisation radiation consists of individual elements installed above radiation dangerous facility. Elements represent massive items of stepped shape, which are made in the form of three parallelepipeds of similar thickness, which compose an integral unit with squares at the bottom, which become smaller in size, or with upper parallelepiped turned through 90° relative to lower one. Middle parallelepipeds of the first and the second elements are equal between each other. Elements are assembled into modules providing the guarantee access to any ionisation radiation source cell when they are removed, and consist of five first elements and four second elements.

EFFECT: improving reliability of protection against ionisation radiation of the facility of any size and configuration; preventing radiation "breakdown" event at joints of individual elements; simplifying removal-assembly and manufacturing procedures.
