[en] The efficiency of the use of personnel protection shielding against intensive sources of ionizing radiation in the areas of work at the Shelter object is analyzed. Data on the practical application of protective shields when performing works to stabilize unstable structures of the Shelter object are presented. The models for the use of special protective cabins for the dismantlement of the Shelter object structures are justified; these models are planned to be implemented after the commissioning of the New Safe Confinement. It is shown, that use of shielding as one of the most effective methods for reducing the collective dose of radiation is crucial.
