I agree with Thomas. Please also consider that in the USA federal and 
state regulations, there must also be a specific percentage of the 
annual (or quarterly) dose limits, that must be exceeded before 
extremity monitoring is required. There are also regulatory guides 
that state that extremity monitoring is generally worn when the 
working environment is such that the extremity dose is > 5 times the 
Deep Dose Equivalent, and, that the Deep Dose Equivalent is > 100 
mrem (1.0 mSv). In all cases, the RSO or individual in charge should 
consider these as well as other working environmental conditions 
before determining that extremity monitoring is needed, or is not 
necessary.
