All teams shall receive an initial briefing on current plant status and radiological conditions prior to being dispatched. A team leader shall be designated for each team.
[ ] NOTE - KI use may only be authorized by the ED per Procedure 5.7.14. KI use will be discussed and appropriate attachment(s) of Procedure 5.7.14 will be completed.
1]4.3 KI will be taken voluntarily at the direction of the Radiological Control Manager or Chemistry/RP Coordinator.
] 4.4 Once the plume is located, a team shall traverse it (travel across it at right angles to the wind direction). Dose rates will increase as the centerline is reached, peak at the centerline, and decrease as the opposite edge is reached.
- 5. BOUNDARY SURVEYS
[ ] NOTE - Steps 5.1.1 through 5.1.8 may be performed by one survey team or several survey teams, depending on the plume location(s).
S] 5.1 BOUNDARY MONITORING 1] 5.1.1 Leave survey instruments on while traveling to survey starting point.
Relay any increased readings to the FTC. Observation of the meter during transit will also establish a background reading.
[ 1 5.1.2 Survey the site area boundary as directed by the FTC. The extent of the boundary survey may be affected by conditions such as weather, river water level, and radio contact.
[ ] 5.1.3 At the monitoring location(s), perform Beta-Gamma dose rate measurement(s) at 3' and at 3" above the ground. Record the results on Attachment 1.
[ 1 5.1.3.1 High Gamma to Beta ratio indicates the plume is overhead.
I1 5.1.3.2 High Beta contribution indicates the plume is at ground level.
I1 5.1.3.3 A high 3" Beta reading compared to the 3' Beta reading indicates there is ground deposition.
I PROCEDURE 5.7.18 1 REVISION 20 1 PAGE 3 OF 17 1
] 5.1.4 While traversing the plume, the centerline is determined as the location where dose rates peak. Air sampling should be performed at centerline per Step 6.2, when Beta readings indicate the plume is at ground level or there has been a ground deposition. A silver zeolite cartridge shall be used to obtain a gross iodine air sample.
[ ] 5.1.5 Attempt to approximate locations indicated on the survey map (Attachment 4 of this procedure) and take readings at each point.
Record the results on Attachment 1.
[ 1 5.1.6 Record dosimetry readings on Attachment 1 periodically and whenever plume affected areas are exited.
[ 5.1.7 Exit plume and determine the iodine and particulate concentrations using Section 7.
[] 5.1.8 Relay survey results to the FTC.
[ 1 5.1.9 Teams shall be provided further sampling instructions by the RAS via the FTC.
1] 5.2 DOWNWIND MONITORING
[ 1 5.2.1 Conduct surveys at distances of- 2 and 5 miles downwind.
Pre-determined monitoring locations at or near these distances may not correlate well with highways or roads. Approximations will need to be made. Communicate clearly when relaying location information to and from downwind survey teams.
[] NOTE - Steps 5.2.2 through 5.2.6 may be performed by one survey team or several survey teams, depending on the plume location(s).
[ ] 5.2.2 At monitoring location(s), teams shall traverse the plume and perform Beta/Gamma dose rate measurement(s) at 3 and at 3" above the ground. Record the results on Attachment 1.
5.2.2.1 High Gamma to Beta ratio indicates the plume is overhead.
[ ] 5.2.2.2 High Beta contribution indicates the plume is at ground level.
[ 1 5.2.2.3 A high 3" Beta reading compared to the 3' Beta reading indicates there is ground deposition.
I PROCEDURE 5.7.18 1 REVISION 20 1 PAGE 4 OF 17
[ 5.2.3 While traversing the plume the centerline is determined as the location where dose rates peak. Air sampling should be performed at centerline per Step 6.2, when Beta readings indicate the plume is at ground level or there has been a ground deposition. A silver zeolite cartridge shall be used to obtain a gross iodine air sample.
[ 1 5.2.4 Record dosimetry readings on Attachment 1 periodically and whenever plume affected areas are exited.
[ 5.2.5 Having exited the plume, the team shall determine iodine and particulate concentrations using Section 7.
11 5.2.6 Relay survey results to the FTC.
11 5.2.7 Teams shall be provided further sampling instructions by the RAS via the FTC.
- 6. FIXED ENVIRONMENTAL AIR STATION FILTER RETRIEVAL/CHANGEOUT
[ 1 6.1 If requested by the RAS, retrieve/changeout the filter/cartridge assemblies at fixed environmental air sampling stations.

S ATTACHMENT 5 CONCENTRATION HAND-CALCULATION Concentrations of radioisotopes may be determined using the following formula:
Concentration of radioisotopes ([iCi/cc)
(3.53 x 10s) x (mrem/hr contact reading)
(CO x (sample volume in cubic ft)
(3.53 x 10s) x (
( x Ci/cc where:
Cf is a correction factor dependant on:
I. Instrument type.
- 2. Probe type.
- 3. Sample collection media (particulate filter or cartridge).
- 4. Isotope/form of interest.
Cf values for the instruments and probe types used at CNS for particulates and iodides are listed below.

ATTACHMENT 6 INFORMATION SHEET DISCUSSION 1.1 In the event of a radiological release, data obtained from off-site surveys shall be used to verify projected release rates, concentrations, and doses. This data also provides a basis for making or modifying Protective Action Recommendations (PARs) per Procedure 5.7.20.
1.2 Once a release is in progress, downwind survey teams shall be used to make gross iodine determinations based upon air sample results. These gross iodine determinations will be correlated against projected iodine concentrations to verify the adequacy of Protective Action Recommendations (PARs).
Correlations between actual field sample readings and projected concentrations should be made periodically as long as a release is in progress.
1.3 Once the release is terminated, additional field sampling results (i.e., soil, vegetation, water) shall be taken to determine the radiological impact and aid in re-entry decision making. These determinations and decisions will involve State and Federal agencies.
