1. Radiation Protection Technology Contamination Control Radiological Safety and Response RPT-243-PE-5

2. Radiation Protection Technology Learning Outcomes Upon completion of this lesson, the student will be able to (cont’d): Demonstrate the ability to perform a radiological survey including: –Pre-survey preparations –Operational checks on survey instruments –General area radiation and contamination surveys –Work area radiation and contamination surveys –Counting loose surface contamination surveys using a GM frisking instrument converting cpm to dpm/100 cm 2 and dpm/LAS

3. Radiation Protection Technology Learning Outcomes Upon completion of this lesson, the student will be able to (cont’d): Demonstrate the ability to perform a radiological survey including: –Surveying items for contamination with a GM frisking instrument –Documenting the results –Recommendations of posting adjustments based on the results

4. Radiation Protection Technology Learning Outcomes Upon completion of this lesson, the student will be able to (cont’d): Demonstrate acceptable behaviors when in and upon exiting a contamination area, including: –Proper wearing and removal of appropriate contamination control clothing –Proper contamination control techniques that minimize cross contamination –Proper use of the step-off pad for exiting and for removal of material Demonstrate the proper use of personnel dosimetry

5. Radiation Protection Technology Outline Explanation Mini-Lecture Dress-Out and Bagging Techniques Section 1 – Contaminated Area Entry and Survey Section 2 – Investigation for Contamination Control Problems

6. Radiation Protection Technology Explanation The same team assignments made in PE-1 will continue into this PE. This PE has two sections. –The first section involves the teams entering a contaminated area and performing a contamination survey. –The second section involves the teams visually inspection an area to determine contamination control problems.

7. Radiation Protection Technology Explanation The teams will be held accountable for the use of proper three-part communication and human performance tools during the PE. The exercise will start with a mini-lecture on proper PC use and bagging techniques for contamination control. A short briefing for the scenario. At the conclusion of the practical portion, a team debrief may be held if time permits.

8. Radiation Protection Technology PC Techniques

9. Radiation Protection Technology In General… Each station issues procedures that describe the details of their personal protective clothing standards. Other techniques may be stipulated through training, department policy or “standing orders” such as: –When disposable PCs are required or –Alternate dressing and undressing techniques developed locally –The use of tape vs. launderable items

10. Radiation Protection Technology The ATC-RPT Standard For the purposes of our PEs, the PC standards that will be used are shown in the following pictures and as described here: –Unless specifically directed, joints are not taped –The wet paint technique is observed for SOP barrier ropes and tape –All items leaving a posted contaminated area must be surveyed clean or bagged – except an individual’s EAD. –Cuff all bags for transferring at SOPs.

11. Radiation Protection Technology The ATC-RPT Standard For the purposes of our PEs, the PC standards that will be used are shown in the following pictures and as described here: –The EAD is to be worn in a whirl pack in the chest pocket of the PC coveralls –The TLD and security badge are worn under the coveralls but within one hand’s breadth of the EAD.

12. Radiation Protection Technology The ATC-RPT Standard For the purposes of our PEs, the PC standards that will be used are shown in the following pictures and as described here: –Upon exiting the Contaminated Area: Before removing the gloves, squeeze the EAD out of the whirl-pack onto the edge of the SOP Upon stepping on the SOP, place the EAD on the lanyard with the TLD Frisk the combo when a hand, foot, and face frisk is done

13. Radiation Protection Technology The ATC-RPT Standard Portable instrumentation taken into posted Contaminated Areas shall be wrapped or bagged in clear plastic to prevent cross contamination. The Instrument wrapping may be wiped with a Maslin upon removal from the CA.
