Columbia's response. Do you use flashing lights for boundary postings during Radiography? No, we post boundary guards at all radiography boundaries. If dose rate monitoring is required the boundary guard will be a HP Technician.

If we employ flashing lights for LHRA controls we specify red lights, Palo Verde would like to know: Do you use flashing lights for boundary postings during Radiography? If so, do you specify a particular color of the flashing lights? Seth ********************************************************************** Seth J.
