/ 3.0i DISCUSSION 3.1 A Radiation Survey is used to detect the presence of radiation, and if found, determine the types, levels, and locations of the radiation present in an area. This information is then used to properly post the area, fill out an RWP, and/or update the plant's radiological status in order to meet the station's policy of keeping radiation exposures "as low as reasonably achievable".

3.2 Topics covered in this procedure as as follows:

Page 8.1 Selecting and Checking the Inffrument 3

8.2 Entering the Area 3

8.3 Performing the Survey 4

4.0 PRECdUTIONS 4.1 The surveyor should be aware of his accumulated dose at all times during a survey. Minimize the dose by utilizing available shielding and remaining in radiation fields only as long as absolutely necessary.

4.2 Never place the instrument in contact with objects since this can affect the reading on some instruments. This also will help prevent inadvertently contaminating the instrument. " Contact" levels are obtained by taking readings as close to the subject as possible without contact.-

4.3 If an instrument seems to be malfunctioning, the surveyor shall immediately leave the area and obtain a different instrument (as per Reference 11.1).

4.4 Carry instruments carefully so they are not dropped or bumped.

4.5 A minimum of two people should be used in areas where respiratory protection is required unless otherwise specified by Health Physics supervision.

  • 5.0 PREREQUISITES 5.1 The surveyor shall be qualified in " Division I" of Reference 11.4.

5.2 The surveyor shall comply with the applicable requirements of a posted RWP prior to conducting the survey.

5.3 If at all possible, the surveyor should obtain information about the area such as expected radiation levels, lighting conditions, and safety hazards.

NOTE:

If inadequate lighting is expected, the instrument's meter will be difficult to read and portable lighting should be taken along for the survey.

SP 62.010.01 Rev. I 9/29/80 Page 2

1 5.4 In highly contaminated areas the surveyor should bag or otherwise protect the instrument from contamination.

6. O' UDtITATIONS AND ACTIONS N/A 7.0 MATERIALS AND TEST EOUIP:!ENT 7.1 Appropriate Portable Radiation Survey Instrument (as per Reference 11.1).

7.2 Radiological Survey Sheet (SPF 62.010.01-1) and the appropriate Plant

<1 Survey tbp (SPF 62.010.01-2 through SPF 62.010.01-27), if applicable.

7.3 A pen or pencil to record the radiation levels on the survey sheet.

8.0 PROCEDURE 8.1 Selecting and Checking the Instrument 8.1.1 Selcet the appropriate survey instrument to be used (as per Reference 11.1).

8.1.2 If the surveyor has not used the selected instrument within the last three month period, or if the surveyor has any doubt as to the proper operation of the instrument, he should obtain and read a copy of the operating procedure for that instrument.

8.1.3 Ucfore making a survey, the surveycr should be sure he knows the limitatinna u the instrunent and hm, to properly interpret the I

in,!icati a W

.;.e l u e. r tue n t.

8.2 Entering the Area i

8.2.1 If the area being entered is posted as a " Contaminated Area" and/or

" Airborne Radioactivity Area", consideration should be given to bagging the instrument in plastic to prevent contaminating it inadvertently.

8.2.2 Prior to entering the area, the instrument should be set on a range which is at least one higher than the range on which the rad.ation level is expected to be read. If levels in the area are expected to be >100 mR/hr, the instrument range switch should be placed on its highest range before entering the area.

8.2.3 While entering the area, the surveyor shall hold the instrument before him and observe the meter deflection while turning the range selector switch down until the appropriate operating range for the radiation levels in the area is reached.

NOTE:

If the instrument is at full scale deflection on its highest range at anytime, the surveyor shall immediately i

i leave the area to obtain higher range instrumentation (as per Reference 11.1).

The Health Physics section (or Watch Engineer if HP is not available) should be notified of any abnormal conditions such as this.

l 8.3 Performing the Survey 1

8.3.1 General Area Surveys 8.3.1.1 Check the general frea accessible to personnel, recording the readings on the survey sheet in cres/hr. Use a icw background area whenever possible to record data.

NOTE:

The instrument should be pointed in all directions from the surveyor including up and down.

NOTE:

Personnel should only take those readings necessar to define the, radiation levels in the work arca.

i 8.3.2 Work Area Surveys i

8.3.2.1 The entire work area shall be surveyed paying particular attention to contact readings of pipes and equipment that=

P the worker might lean or rest on.

8.3.2.2 The surveyor should try to locate an area of relatisely low radiation levels and indicate this on the survey sheet. Personnel should make a concerted effort to stay in the lower radiation level areas as much as possible.

8.3.2.3 While conducting this type of survey involving high dose rates, the surveyor should obtain the dose rate and back away to lower exposures to record the data.

s 9.0 ACCEPTANCE CRITERIA i

N/A 10.0 FINAL CONDITIONS 10.1 Observe any postings in the area and report any discrepancies between the postings and the newly conducted survey to the Health Physics section (Reference 11.3).
