NOTE: Plume location and dose rate information shall be reported as soon as possible.
This information is vital for Dose Assessment and Protective Action Recommendations.
- b. Traverse the suspected area to determine the existence, outer boundaries, centerline, and respective dose rates of a release.
- 1. Using a high range ion chamber, traverse the suspected area, monitoring the meter continuously.
- 2. When an increase in dose rate is noted, record time, dose rate, and relative site location.
- 3. Continue monitoring dose rate increases to the centerline, where the dose rate will be at a maximum. Periodically check open vs closed beta window dose rates for the presence of the plume at ground level.
Proc No El-B Attachment 1 ONSITE MONITORING TEAM LIST Revision 12 Page 5 of 8 NOTE: An Emergency Van with an Inverter, or some other power source is needed to power the Air Sampler. If power is unavailable, the Air Sample is not required.
- 4. At the centerline, unless high dose rates prohibit, obtain an air sample (iodine and particulate) and survey for dose rates at three inches and three feet from the ground. Check open and closed beta window dose rates, and take smear(s) for loose surface contamination. Ifcenterline open/closed window readings indicates there is no ground level plume present, the air sample and surface contamination surveys may be omitted.
- 5. Continue monitoring dose rates to the opposite plume boundary, and record the relative site location of the outer boundary.
- c. Check self-reading and electronic dosimeters frequently (ie, entry into plume, exit from plume) and record times and dose received. Dose received per plume entry, in addition to previous dose received in the current year, should be closely tracked to ensure authorized dose control levels are not exceeded.
- d. When traversing or sampling in a ground level plume, and/or projected or known airborne activity indicates caution, evaluate necessary protective clothing.
Proc No El-8 Attachment 1 ONSITE MONITORING TEAM LIST Revision 12 Page 6 of 8 SECTION 4: EVACUATION MONITORING
- a. Proceed to the assigned Control Point/Monitoring Station (established at:
Security Bldg; North Beach Gate; or Inner Gate to South Radwaste) and ascertain habitability prior to establishing the monitoring station. If personnel cannot be deconned at the selected station, then bag or contain the contamination as best as possible and send them on to the designated Reassembly Area.
- b. El-13, "Evacuation/Reassembly," implemented: Personnel surveyed, dosimeters read, dosimetry collected, etc.

Attachment 1 ONSITE MONITORING TEAM LIST Revision 12 Page 7 of 8 SECTION 6: AIRBORNE SAMPLING AND CONTAMINATION SURVEYS NOTE: Lapel Air Samples, iftaken, shall only be analyzed using HP 2.19, "Airbome Radioactivity Sampling."
- a. Field collection under emergency conditions should be a 5 ft3 sample, normally obtained by taking a 2 cfm sample for 2.5 minutes. A shorter sample would be appropriate in the presence of high dose rates.
- b. Complete Sections 1 and 2 of Attachment 2 to document dose rates, contamination levels, and air sample data to determine corrected volume.
Section 1 is to be completed for every air sample taken.
- c. Carefully remove filter and cartridge. Mark the direction of air flow on the silver zeolite cartridge with an arrow. Handle filters with care to prevent cross contamination or loss of collected material, using tweezers when possible.
- d. Perform initial gross analysis using a PRM-6 count rate meter with an HP-21 0 probe or equivalent.
- e. Field determination of particulate Airborne Activity:
- 1. Determine the background count rate with the HP-21 0 probe or equivalent in place on the sample holder.
- 2. Place the particulate filter in the sample holder, upstream side up.
With the HP-21 0 probe or equivalent in place on the holder, the filter should be approximately % inch from the detector.
- 3. Determine the gross particulate count rate.
- 4. Complete Section 3 of Attachment 2.
- 5. Place the sample In a bag or envelope, label with date, time sample 2 started and ended, average flow rate, location sample was taken, and initial.
Proc No El-8 Attachment 1 ONSITE MONITORING TEAM LIST Revision 12 Page 8 of'8
- f. Field determination of gross iodine activity.
- 1. Determine the background count rate with the HP-210 probe or equivalent in the counting area.
NOTE: Backside readings at 1/2" are preferred, but if count rate is negligible use the front side at 1/2".
- 2. Determine the gross iodine count rate by placing the HP-210 probe or equivalent 1/2N from the backside of cartridge.
- 3. Complete Section 4 of Attachment 2.
- 4. Place the cartridge in a bag, label same as for the particulate filter.
- g. Save all samples for further/future analysis, storing high-level samples in a shielded area. If isotopic identification of air samples is desired, use the low-level counting room MCA in the Service Building, if available.
- h. Reevaluate protective measures necessary (protective clothing), based on determined airborne activity levels.
