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.

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