3.0 DJSCUSSION 3.1 Survey data for the termination survey are collected and stored on various storage media.

3.1.1 Data from smear counting are automatically stored in the computer of the Canberra 2400 Counting System and automatically downloaded to a storage disk at the end of each counting cycle.

3.1.2 Field survey data from survey units are stored in the Eber11ne ESP 2 Data Logger and downloaded using the ESP-2 software.

3.2 Data from non-storage instruments, such as the Bicron pRem Gamma Survey Meter, are recorded manually on the Termination Survey Data Sheet (TSDS).

3.3 This procedure contains:

fs 8.1 General

( \ 8.2 Transferring Data 8.3 Survey Unit Survey Completion 4.0 PRECAUTIONS To prevent loss or corruption of dats in data-storage i ns t rurnent s :

4.1 Maintain personal custody of instrtunent frcm sign out until turned in for downloading.

4.2 Do not drop or shock instrument.

4.3 Do not erase instrument memory until data has been downloaded.

4.4 Do not place instrument or storage media near elevated temperatures or a magnetic field.

5.0 PREREQUISITES 5.1 Personnel performing collection or processing of terminatiori survey data shall review and understand the contents of this procedure.

5.2 This procedure will be used by Health Physics Technicians performing termination surveys, Health Physics Foremen and by Terraination Survey Rad Engineers.

for the related survey unit indicating survey unit number and survey unit name. Each disk shall be dedicated to a specific survey unit and kept in its survey unit file once survey _ data has been downloaded to it.

8.1. 2 Fil e Naminr.

8.1.2.1 ESP-?

Data files downloaded from the ESP 2 to a PC subdirectory are renamed before copying to the survey unit disk. The format for renaming includes the survey unit number followed by a sequence letter, the day of the month and the file extension TXT. For example, the file name for the first set of data downloaded from survey unit TB019 on the 26th of the month would be i

TB019A26.TXT. The second set of data would be TB019B26.TXT. The first see of data from the same survey unit the next day would be TB019A27.TXT.

8,1.2.2 Canberra 2400 Countinr. Sh t.e.l0 Data from the Canberra 2400 we copied from the Canberra l disk to the survey unit dis r.) . Files an automatically named by the Canberra software for the survey unit number, and include a sequence letter, the day of the month, and have the file extension DAT. For example, TB019A26.DAT.

8.1.2.3 OC Replicate Survey Data i

Data recorded for QC replicate surveys on the ESP 2 or Canberra 2400 are repeat measurements at original survey locations and are identified with those location codes.

In order not to overwrite the previously stored files, the above named convention is followed except the file extension is QCA for the ESP 2 and QCB for the Canberra 2400 Counting System.

8.1.3 Non-Data Storare instrumentation For non-data storage survey instruments and when storage devices such as the ESP-2 or Canberra 2400 are not available, survey data is manually entered onto the TSDS and smear survey data is then printed out by the Tennelec printer. If the SAC 4 is used, these results shall be manually added to the printout. These forms are-included in the survey unit survey pachage and entered into the database manually.

8.2 IRANSFERRING DATA 8.2.1 ESP-2 i 8.2.1.1 When a survey of a surver unit is complete or at the end of the shift, whichever is sooner, the llP Technician ,

shall turnover the ESP.2 and the survey unit package to the Termination Survey Instrument Cage. I ;}

8.2.1.2 The llP Foreman shall ensure that the ESP-2 and the TSDS are transferred to a Termination Survey Rad Engineer for downloading to a pc.

,i 8.2.1.3 The Termination Survey Rad Engineer, or his designated representative, shall download and transfer the data from ESP-2 memory to the pc as follows:

.1 Connect cable from the pc RS-232 port to the ESP-2.

.2 Turn on the ESP 2.

.3 Bring up the ESP 2 software program on the pc.

.4 Select option to " download data to a file" and

" print data to a printer",

( ,) renamed as described in 8.1.2.1.

.7 The printed output and the TSDS shall be turned over to the responsible Termination Survey Rad Engineer who shall check the data for correctness ,

and completeness before its inclusion into the I termination survey data base and survey unit  !

package. If the survey data is not correct or complete, the TSDS(s) shall be returned to the !!P Foreman for amelioration.  !

,8 The survey unit disk files, along with the TSDS, are transferred to the database-data entry clerk for entry ind downloading to the termination survey data base.

.9 Vhen the survey unit survey is complete, the survey unit dish will be transferred and included in, the survey unit package. If the disks are -

stored in a disk holder, then a note in the survey unit package shall be included to show the location of the disk.

8.2.2 O nherra 2400 Countinr. System (Canberra 2400) m

( ) 8.2.2.1 Smear counting data are automatically loaded and named

\d to a disk for each survey unit as described in 8.1.2.2.

except for the file extension which is named DAT. A hardcopy of each data file is simultaneously printed.

8.2.2.2 When a disk is full, or at the end of a shift, whichever is sooner, the HP Foreman shall transfer the Canberra disk and printouts to a Termination Survey Rad Engineer.

8.2.2.3 The Termination Survey Rad Engineer or his designated representative shall copy the Canberra 2400 disk files to the appropriate survey unit disk (s). After all files are copied, the disks from the Canberra unit may be reused. The printouts are given to the Rad Engineer responsible for th" survey unit.

8.2.2.4 The survey unit disk files along with the TSDS are transferred to the Database Data Entry Clerk for entry and downloading to the termination survey data base, 8.2,2.5 When the survey unit survey is complete, the survey unit disk will be transferred and included in the survey unit package or stored as described in 8.2.1.3.9.

.1 The 'lSDS is filled out by the llP Technician and turned over to g the itP Foreman along with the ESP 2.

,m

! ) .2 The llP Foreman shall turnover the TSDS and the ESP-2 to a

\~-) Termination Survey Rad Engineer to allow for data downloading.

.3 The Rad Engineer, if not the one responsibic for that survey unit, shall transfer the TSDS and the EGP 2 printout to the responsible Rad Engineer.

4 The responsible Rad Engineer, after verification of the data, shall transfer the TSDS to the Database Data Entry Clerk for input into the database and ensure that the TSDS and the ESP 2 printout (s) are included in the survey unit package.

8.3 Survey Unit Survey Completion k' hen the survey unit package is complete, all data verified and printed out, and the database has been backed up to tape or disk (done on a weekly basis), the survey unit computer disk (s) may be erased and prepared for reuse with the prior approval of the Termination Survey Engineer.

9.0 ACCEPTANCE CRITERIA The Termination Survey Data sheet (s), printouts from the ESP-2 ano smear data must be correct and agree with the survey design bsfore being accepted and included in the termination survey database and survey unit package.

rml0.0 FINAL CONDITIONS

\n-k' hen the survey unit survey is complete, the data loaded onto the terinination survey database and verified complete and correct by the Termination Survey Rad Engineer responsible for the survey unit, then the TSDS(s), the smear data sheet (s) and the survey unit computer disk, if retained, is filed with the survey unit package.
