North Anna does use rad rope between the stanchions. Exception include if it is physically impossible to run the rope due to structural interferences, etc. We use a short section of "bungee" rad rope across the doors of a sealand container. For doorways we may use just a single stanchion and rad tape at the boundary.

We might use several Radiation Area postings on stanchions, placed around a B-25 that met the 5mR/hr at one foot criteria for being a Radiation Area, for example, without connecting all of the postings/stanchions using rad rope. Question: Does your site post Radiation Areas similarly, or do you require Radiation Area postings/stanchions to be linked together using rad rope?
