5.1.4 Prior to. leaving equipment storage location, obtain ,necessarycommunicatione equipment and assure its operability by establishing <
communications with the TSC. Inplant survey teams will utilize radiochmmel #1 (Inhouse repeater) and will be identified by numericaldesignations (ie. Inplant 1,2,3, etc.).
5.1.5 When accompanying Damage Control Teams, verify that a Radiation Work -Permit has been written and that team members are properly outfittedwith protective gear and dosimetry.
5.1.6 When conducting surveys separate from Damage Control Team entries,proceed to the locations requiring monitoring per step 5.1.1, and useappropriate station floor plans and survey forms contained in theInplant Emergency Survey Binder to record results. Furthermore,ensure that a HRA Entry and Survey Log or a Radiation Work Permit isfilled out to record exposures of survey team members.
5.1.7 If airborne activity is suspected because of:A ventilation monitor in the alarm condition, ora.
b. A CAM in the alarm condition, orc. Visual observations detect the presence of steam which could be
radioactivethen:
_
Full protective clothing including Scott Air Paks should bedonned.
5.1.8 a. If the survey consists of taking radiation measurements on thestack sample line when the stack monitor is approaching itslimit per N1-PSP-12, ensure the 4 "C" cell batteries designatedfor use as spares in the installed interim High Range StockMonitor are brought from the Control Room Dose Estimate Cabinetor Station Storeroom to the 256' elevation of the Screenhouse,
b. When entering an area of suspected radiation, the survey meters(normal and high level) should first be on the highest range ofthe instrument, then downscaled until a reading is obtained.The Teletector Probe should be extended so that distance can beput between the surveyor and the probe.
i
c. When conducting surveys, voice communications (e.g. radio,,
Gaitronics, etc.) with the TSC or Control Room should be - 7,
i
| maintained as appropriate. In addition, when approaching an; area requiring monitoring, do not approach the level via thel
elevator. Use stairs only.
3.1.9 a. The area should be entered cautiously making observations of anyfailed equipment which could have caused the alarm,
b. Survey area to verify validity of monitor readings as per RP-3" Performance of Radiological Surveys". Survey the area asquickly as possible to ascertain the cause of the highradiation. Note any unanticipated high radiation levels, theirlocation, and time and date of reading.

5.1.10 If dose rates greater than 10,000 mrem /hr are encountered, exitimmediately and report results to the S tation Survey / Sample Team. .
'- Coordinator, per Step 5.1.1, or others, as directed. Area should be
reentered only after a survey planning session has been held perEPP-15.
5.1.11 If airborne activity is suspected, a high volume air sample vill betaken in the suspected area (2 to 10 micute Particulate and Iodinesample) as per N1-RTP-75. Record flow rate and the time the sampleis started and stopped on Figure 1. If field analysis is possiblecontinue with Step 5.1.12, if not sMip to Step 5.1.13.
5.1.12 After obtaining samples, travel to an area of low background(preferably < 300 cpm but not to exceed 500 cpm) and run highvolume air sampler for approximately 1 minute to clear inert gasesfrom the cartridge.
NOTE: If sample (s) have been taken on Silver ZeoliteCartridges (s) the post sampling purge is not required.
Obtain a background count and count the particulate filter and lodine,
cartridge separetly. During counting hold the probe approximately '
1/2 to 3/4 inch from the cartridge or filter and count for a total Itime of 1 minute. Log the maximum count rates obse ved en the survey 7data sheet (Figure 1).
5.1.13 The results of all surveys shall be immediately recorded on Figure j1.0 and reported (via radio, Gaitronics, etc.) to the Station i

a. Surveys should always be made by at least two surveyors,b. *4 bile traveling to the survey sites, the survey meters should be
turned on in the vehicle and observed by the passenger.c. Any abnormal readings observed while on the way to the survey
site should be noted for possible followup investigation. Thisdata should be noted under the moving survey section of Figure1, "Inplant/ Downwind / Reentry Survey Data Sheet".
d. Make every effort to conduct surveys as near as possible to thedesignated points.NOTE: Ground level releases are expected to result in
maximum radioactive concentrations at or near the siteboundary. Elevated releases may result in producingmarimum radioactive concentrations at varying ;
dist=nces from the site boundary.e. At each survey point, gamma dose rate and/or air sample
measurements should be taken (see step 5.1.6 for further 6 i
instructions). Results of the measurements shall be transmitted 1
back to the TSC or EOF as indicated per step 5.1.1. If radio is i |f.inoperative, use coins available in kit to telephone results
back to location indicated in step 5.1.1. Telephone directory |1s available in the Emergency Survey Binder for references. r
f. At each survey location, determine the maximum area of
concentration by scanning to the left and right of the expectedsurvey area. At the area of highest dose rate commence airsampling and/or doserate survey. -

; 5.1.7 Samples / Measurements
. a. _s , f Dois Rate Measurements
i Two different readings (ground level and waist level) are takenat each survey point. These two readings should assist in the
i evaluation of whether the activity is coming from an overhead'
plume or a ground deposit. Reading will be taken after the airsample has been started at a given location, if an air sample is-
required.
Ground Level ReadingsGround level contact readings should be taken at three survey-
points within a circle of about 25 yards in diameter using a;. c)unt rate meter. Readings over 20,000 c/m should be taken with'
a dose rate meter. Record open window and closed windowreadings. Record and report only the highest of the threemeasurements.
Waist Level ReadingsWaist level readings (approximately 3 ft from the ground) shouldbe at each of the locations where a ground level reading is
-
taken._ Readings over 20,000. c/m should be taken with a doserate meter. Record open window and close window readings.Record and report only the hi:; hest of the three measurements.
_
b. Air Sample Measurements
Air samples should be obtained at the plume centerline and atk other locations, as specified' (ie plume edge). Other air
,
samples should be collected for backup data after the primarysampling is completed.
'
. Using a portable high volume air sampler (AC or DC depending onpower source) loaded with both particulate filter and iodinecollection cartridge, obtain a 5-20 minute sample (approximately
'15 cubic feet). Record flow rate and the time the sampler isstarted and stopped.NOTE: Silver Zeolite sampling cartridges shall be used until
it has been determined that noble gas interference ofair samples measurementa is not a problem.
Sample filters, cartridges and/or liquid samples shall be placedin separate containers (e.g. envelopes, plastic bags, etc.) toavoid cross contamination of samples and counting facilities.
After obtaining air samples, travel to an area of low background( <100 cpa) and run the high volume air saapier forapproximately 1 minute to clear inert gases from the cartridge.
fNOTE: If sample (s) have been taken on Silver Zeolite
Cartridge (s) the post sampling purge is not required.!

b. Monitoring' should be performed over a three sector area '(e.g. -'
that is one 22 1/2" sector on each side of the affected sector)6-
until the puas centerline has been established off-site. -
NOTE:- During lake breeze conditions, it is possible for theplume to diverge from the prevailing costal winddirection once it meets the inland air mass.Therefore, during postulated lake breeze conditions(i.e. wind direction from north) it may be necessary
0to expand survey area to 45 on either side of theplume sector in order to define the inland directionof plume.
Advise survey teams whenever it appear's that the wind directionc.has shifted more than 22 1/2* during the monitoring period.
d. Direct, if necessary, survey teams to collect and replaceazisting emergency and environmental T1D's, beginning with theT1D's downwind of the plume.
e. Direct, if necessary, the- initiation of the expanded,
environmental monitoring program based on the release conditions(n.g. water for liquid releases, grass and milk samples for
6iodine releases).
5.2.7 As survey results are received via the survey Report Form (Fig. 2),calculate dose rates and airborne concentrations using Fig. 2 and
-
v)forward data to the Radiological Assessment Coordinator. Perform anevaluation of the following areas per each location.
. a. The whole body immersion dose rate will be due mainly to noblegases. This may best be estimated by the waist (3') dose ratereading directly in mR/hr.
b. Noble gas airborne . activity any be calculated using thefollowing formula: 6,

4) In addition, the ratio of Iodine-131 concentration to gamma.exposure rate concentration should be approximatelyconstant for different locations if the measurements arenot spread out over more than about 2 hours and the releaserate has been fairly constant over the period. Therefore,the process of collecting and analyzing a few air samplesand estimating Iodine concentrations based on tne
