Cooper Nuclear Station trains workers to maintain these in close proximity of each other in RAD Practical Training. We have procedural guidance to keep them within a hand width. When a bag is used it is for contamination control purpose only, when PCs are worn that would cover these devices, they are placed into a bag attached to the outside front torso or re-located to the most appropriate location, i.e. head or back, etc.
