Lesson Learned Statement:Electronic dosimetry can save time that would otherwise be spent attempting to read a direct reading dosimeter while in a work area.
Discussion:The project entailed the decontamination of the Acid Recovery Pump Room (ARPR) in its entirety. Decontamination efforts encompassed the removal of all loose debris from the ARPR and vacuuming the ARPR floor. Permanent utilities to the ARPR had to be isolated. The process lines within the ARPR were drained of liquids as necessary and subsequently isolated to ensure against inadvertent intrusion of additional liquids. The tank, pumps, electrical and instrumentation components, process and utility piping, HEPA filters, and miscellaneous debris were size reduced as necessary and removed from the ARPR. The final state of the ARPR is that the walls, ceiling, and floor are free of any components or equipment.
Analysis:Electronic dosimetry was used during project work activities. The electronic dosimetry provided a live time remote readout of the workers entry exposure. Dose rate information was displayed on the remote readout. The use of this system saved time otherwise spent attempting to read a direct reading dosimeter while in the work area. It also saved time which would have been spent unwisely by ending an entry early due to the use of a single dose rate value to calculate the stay time.
