Commentaries: Art. 84

Before persons leave, or materials are removed from, controlled areas, it must be ensured that the guidance value specified in Annex 3 Column 12 for surface contamination is not exceeded. For the clearance of materials, the requirements specified in Article 106 apply.
If, in controlled areas, the contamination of materials and surfaces is greater than 10 times the guidance value specified in Annex 3 Column 12, decontamination measures must be implemented or other appropriate protection measures adopted.
If, in controlled areas, part of the contamination will remain attached to the surface under foreseeable conditions of handling, the guidance values specified in Annex 3 Column 12 shall only apply to the transferable contamination.
