I submitted the "primary" versus "secondary" dosimeter clarification

["Sandy Perle" <sandyfl@EARTHLINK.NET>]

I submitted the following comment back to the NRC, per the recent 

dialogue, to categorically clarify my position regarding secondary 

dosimetry not coming under the auspices of the proposed rulemaking:



Clarification to my proposed revision to 10 CFR 20.1501[c], as 

published May 5, 2003



1. The intent is that only dosimetry used as a primary dosimeter 

shall require accreditation per the proposed rulemaking.



2. The intent is not for secondary dosimetry, that is dosimetry used 

in the event the primary dosimeter is lost, the calculated dose is 

questioned due to anomalies, the dosimetry is improperly worn, or 

other investigated reason, the primary dosimeter can not be used to 

assign the final dose of record.



3. Item 2 is currently the accepted method by the NRC and state 

regulatory agencies, and my proposed rulemaking does not intend to 

modify this practice. The intent is only for primary dosimetry to be 

accredited.
