4.8 Perfo r i logical surveys (as cted by the RAC).
4.8.1 fonn dose rate surve with the R0-2( A):
First take an open window reading at waist level, then take a closed window reading at waist level. Enter these readings and duration of meter readings on the Attachment I.
Calculate true Beta dose rate and enter this on Attachment I.
Report closed window reading and true Beta dose rate to the RAC.
4.8.2 Perform contamination surveys if directed by the RAC as follows:
2.0
1004.10 Revision 4 Obtain smears and coin envelopes from emergency kit, label envelope with date, tir.e and location. Wipe the smear over a 100 cm2 (4 in. x 4 in.) ama. Count the smear with RM-14/HP210 if available and background is less than 300 CPM.
If background is too hig move to an area of acceptable background in order to co t ars.
Enter gross CPM and BKG CPM on Attac btract background from gross CFM to obtai
. ' Report net CPM for h smear to the RAC.

4.10 If radio connu s are lost and t. pager is activated, attempt to sh radio commu ibot with the RAC.
If radio c u
ions cannot be
-e lished, attempt to conta r monitoring t t
lay infomation. If con annot be established, rive to the nearest telephone and call the RAC (948-8069, 948-8070, 948-8071) or the EACC (if transfer has been made) at 944-3737, 944 2648, 944-6709.
4.11 Minimize personnel exposums by moving out of areas of high radiation when recording data or awaiting further instructions by the RAC.
4.12 Ensure all team members keep track of their exposure on Attachment II.

1004.10 Revision 5 4.13 Maintain all completed Attachment I's for permanent records.
Request direction from the RAC as to the disposition of these completed forms.
4.14 Notify the RAC when approaching 300 MREM. Recommend to the RAC that your team be relieved if possible. Relief should be conducted in a low radiation area.
4.15 Retain all samples for later counting and a Samples may be returned to the H.P. Lab or designa lection point at a convenient time as directed by 4.16 When the E tal Assessment C Center (EACC) is activat the Environment ssment Coordinator (EA )
