Nuclear facilities. Ventilation penetrationsfor shielded enclosures Ingestion-build-189776 with a rated heat input1 Scope This International Standard specifies the requirements for the construction and the installation of radiobiological shielding devices used as ventilation passages through shielded enclosures with concrete or leaded walls to protect against gamma radiation. This International Standard applies to all shielded containment enclosures used for handling radioactive products or material emitting penetrating radiation (gamma or neutrons) in such
