4. Early PhaseFocuses on quick results for immediate protective action decisionsWorker protectionPublic shelter / evacuationIntermediate PhaseFocuses on Derived Response Levels (DRL)Re-entry decisions Examining crop embargo areasLate PhaseFocuses on environmental / clean-up levels Sampling Evolution

7. Survey the sample location (if possible)2.5 cm (1 in.) contamination level1 m (waist height) exposure rateUse clean sampling toolsrinse and survey prior to use (if necessary)use plastic sheets / bag as clean work areaUse gloves when samplingchange out gloves after each sampleWhen Collecting Samples
8. Picture of Sample AreaWhile collecting a Sample step back and take a picture of the sample areaThis helps Assessors understand the areaSubmit photo with the sample or measurement

10. Air Sampling10
11. Plume TrackingRe-suspensionpublic / general populationemergency workers – hot line, laboratory, etc.Air Sampling
12. Low Volume0 to 10 CFM approximatelyTrue breathing rateMost commonly used for sampling at Nuclear Power PlantHigh Volume> 10 CFM40 CFM is our standardIdeal for Grab SampleLarge volume of air in a short timeLow Volume Versus High Volume
13. Filter type depends on the contaminant to be measuredHigh VolumeGlass fiber filter paperLow Volumehigh-efficiency filter paper alone or with a charcoal cartridge Air Sample Filters
14. Assemble the Sample HeadCollect a Low Volume Air SampleInstall paper filter.Install charcoal filter.Assemble head.
15. Collect a Low Volume Air SampleLocate the pump out in the open away from buildings, trees or other overhead obstructions.Survey the area (Exposure Rate & Contamination).Position sample head approximately 1.5 meter off ground, in the direction of the release.Choose a Location
16. Turn Pump ON.Start the Air SampleInsert assembled head into air sampler.Record Start Date/Time and Flow Rate on bag and paperwork.
17. Turn Pump OFF.Stop the Air SampleRecord Stop Date, Time & Flow Rate, or Total Volume on bag or paperwork.
18. Complete a separate Sample Control & Chain of Custody Form for each sample and input into the Tablet. Package the SampleUsing Tweezers, Place Paper and/or Cartridge into separate Sample bags.
19. Ground Deposition Soil Sampling19
20. Sample taken are 2 cm deep x 100 cm2Looking for ground deposition before the contamination has migrated. Can include: Soil, RocksGrass, Leaves & TwigsA sealable bag is the default standard containerThe sample can be transferred to other containers as neededGround deposition and standard soil samples use the same equipment. Difference is the content of each sample. We’ll go over how to collect asoil sample. Ground Deposition Sampling
21. Soil Sample Tools
22. Collect a Soil SampleGather the needed equipment place in a bag to carry to collection site.Locate the sample out in the open, away from buildings, trees or other overhead obstructions
23. Collect a Soil SamplePush Jig to 2 cm depth. Tap with Hammer if needed.Survey the area (Exposure Rate and Contamination).
24. Dig trench with trowel, use claw hammer If needed to loosen soil. Collect a Soil SampleSlide Trowel under jig, use hammer if necessary to push trowel under the jig.
25. Pick up Jig and Trowel with the sample. Pour content into 1 gallon Sealable Bag. Collect a Soil SampleRoll the bag around the sample. Keep the opening away from breathing area.
26. Place a Security Seal on the bag.Collect a Soil SampleComplete the Sample Control & Chain of Custody Form and record data.
27. In addition to surface deposition, soil depth migration will need to be assessedCore sampling will depend on special procedures and soil composition and be developed in field.Soil Samples at Depth
28. Water Sampling28
29. Early PhaseSurface Rain (standing water)Public DrinkingIntermediate and LateWellsPublic DrinkingSedimentsWater Sampling
30. 3.5 liter CubetainerRinse Cubetainer with waterAvoid areas of debrisWater Sampling
31. Survey the nearby area (Exposure Rate and Contamination)Collect a Water SampleGather the needed equipment place in a bag to carry to collection site.
32. If needed attach the rope to the bucket.Collect the surface water.Collect a Water SampleUsing the funnel fill the 3.5 liter container. Stop 1 inch from the top.
33. If needed using an indelible marker, write the SCF Number on the Cubetainer.Collect a Water SamplePlace into a clean plastic bag.
34. Vegetation Sampling34
35. Early Phasesamples chosen to match pathway to mananimal feed and/or grassleafy vegetablesFruitsLate Phasestanding cropsroot vegetableslong-term samplingVegetation Sampling
36. Locate the sample out in the open, away from buildings, trees or other overhead obstructions.Collect a Vegetation SampleGather the needed equipment place in a bag to carry to collection site.
37. Only collect the edible portions of the plant. Clip pieces 16 cm or less. Stop before the bag is bulging and will not seal.Collect a Vegetation SampleSurvey the area (Exposure Rate and Contamination).
38. Complete the Sample Control and Chain-of-Custody form and record information.Collect a Vegetation SampleMeasure the length, width, and depth of the sample collected
39. Milk and Feed Sampling39
40. Dairy locationsFarmsTransfer stationsProcessing plantsFeed sampleStored feedOpen rangeMilk and Feed Sampling
41. Integration with state and local responders is invaluableDuplicate sampling is preferred rather than splitting samplesChain of custody is maintained for all samplesMilk Sampling

44. Consider all samples and paperwork to be contaminated until surveyedRemove all outer bags to retrieve the sample and paperworkComplete a contamination survey (Fixed and Removable)Complete a contact dose rate of the sampleSample Receipt – Contamination Control
45. If contaminated, decontaminate or double-bag the container, as appropriate.If paperwork is contaminated, transfer the information to a clean Sample Control form.Sample Receipt – Contamination Control
46. Check for evidence of breakage or leakageCheck for paperwork discrepanciesCorrect sample typeDates/timesIncomplete data entries Check for sample acceptability by laboratoryDose rates and contamination values are below laboratory limitSample Receipt & Inspection
47. Sample Control personnel will document any observed non-conformancesField Monitoring personnel must sign the Chain of Custody to transfer custodySample Control personnel will:Accept the sample by signing the Chain of CustodyLog the sample into the Sample Control Logbook.
