Our dive work is typically suppression pool or torus crud cleaning with a vac 
or work in a PWR upender pit.  Normally have 5 locations, lower thighs, chest, 
and lower arms above the elbow with a transmitting DMC2000 ED on each feeding 
into a single iMux transmitter.  Use finger and toe rings.

Lower thighs typically come up highest dose, but still issue for other 
locations since water is a high density working fluid such that single 
dosimeter relocation would not detect a problem elsewhere on the body...

We use a fishnet vest with about a quarter inch mesh so that we can tie-wrap 
the dosimeters in the right location.

Subject: [EXTERNAL] [powernet] Diving dosimetry question

South Texas Project would like to know what other NPP are doing for diving 
operations as far as the number of SRD and DLR and the locations used. For 
example how many DLR and SRDs are used for each diver and do they place a SRD 
on extremities i.e. wrists/ankles?

Thank you,
