Browns Ferry is currently diving in the equipment pit cutting up the Steam Dryer and we are using 8 OSL dosimeters including the one on the back. We have transmitting SRDs on all of those locations but the head. The head has a SRD in addition to OSL but cannot transmit it due to seal around divers neck. We also use extremities but no transmitting SRDs on those. Below are the locations we are using

Please use caution when opening. Susquehanna dove in the U2 suppression pool in 2017. Baseline WBC and urinalysis was performed along with post-dive WBC and urinalysis. Dosimetry multipacks included: Extremity dosimeters on fingers and toes (no associated EDs) Dosimeters with EDs on: Left/right thigh Head Right/left arms Chest I believe all locations with EDs were transmitted to remote monitoring via teleview. I would need to double check with instruments if you're interested in that information. Let me know. Assigned dose was based on highest exposed location of whole body. Our procedure allowed the option of a back dosimeter, but it was not necessary based on the expected rad conditions. One issue we ran into was a lot of pushback on the dosimetry requirements, particularly regarding the back dosimeter before the dive company understood that it was not going to be required for this type of dive.

For example how many DLR and SRDs are used for each diver and do they place a SRD on extremities i.e. wrists/ankles?
