Re: Wear of Control Badge (Re: Extremity Dosimetry)

We have personnel wear their body badge at all times when working in 
restricted areas/radioactive materials.  We have them attach the ring to 
the body badge when not working with radioactive materials but in 
arestricted area.  At the end of monotoring period the extremity dose is 
the reported extremity dose minus the body dose.
