<p class="MsoNormal">Here at Surry, the Decon staff does all the setup as well as the DOP/ PAO testing. DOP testing is performed every two years requiring a 99.97% efficiency. HP controls when and where vacuums and HEPA’s are set up. HEPA’s and vacuums are
stored in a locked sea van when not in use. Power cords on vacuums are kept locked when not in use, HEPA filter units power cords are not locked. HP technicians control the keys to the vacuums. A tracking sheet is used to record the locations where HEPA’s
and vacuums are set up. All HEPA’s and vacuums have a specific tag attached to them which identifies them as radioactive material and provides a location to record the current dose rates as well as inspection criteria. A separate DOP testing label is also
attached to all units. We inspect all units daily when in use. Change out criteria for dose rate would be based on a challenge to the current posting, a challenge to the dosimeter setpoints, or a challenge to reasonable alara principles.<o:p></o:p></p>
