Seth, Since the area for average dose was changed from 1 to 10 square centimeters (RIS 2002-10), San Onofre no longer separates skin dose from discrete particle contamination.
Any skin contamination from discrete or distributed contamination that results in a dose calculation is summed and reported and recorded as SDE.

Does your facility perform field monitoring for discrete particles on personnel? a. If so, at what threshold (e.g. - open window RO-2 reading of 60 mrem/hr) is a formal dose evaluation performed? b. If so, are discrete particles below the threshold simply discarded or is the event documented? c. If so, what is the maximum time between monitoring? d. If so, what threshold is used for entering the dose into your dose tracking data base? 2. For personnel contamination events, what threshold is used for entering the dose (SDE, WB or ME) into your dose tracking data base? 3. Does your facility report SDE from discrete particles in Box 13 (SDE, WB) or Box 14 (SDE, ME) of the workers Form 5 with a comment in Box 19 (Comments) or only in Box 19. ********************************************************************** Seth J.
