Watts Bar replies:
We have a standardize procedure that evaluates the exposure received performing the work with and without a respirator. Contamination, type of work, re-suspension factors and work area dose rates are factors calculated to determine to received dose. We do not have a threshold - it merely calculates which way the worker will receive the dose. From: [email protected] [mailto:[email protected]] On Behalf Of THOMPSON, THEODORE W Sent: Tuesday, September 13, 2011 8:40 AM To: [email protected] Subject: Powernet: significant dose difference I was wondering if any facilities have a set dose limit to identify the term significant when it deals with TEDE-ALARA. In other words, do you have a dose limit difference that you use to establish when respiratory protection equipment or engineering controls are required. (i.e. 10 mrem) If an individual would receive 10 mrem more not wearing a respirator, than wearing a respirator do you require them to wear a respirator? Thanks for your input.
