Most Technical Specifications, in Section 6.12, "High Radiation Area," require that each area in which the dose rate is between 100 and 1000 mrem/hr be "barricaded and conspicuously posted as a high radiation area ...."
So make sure your inspectors have bought-off that the head-high postings meet the "barricade" requirement. I know a lot of plants were going back to having something at waist level...
