C. Areas a RW I Trained Person Can Enter
The level of training a radiological worker has successfully completed determines the types of
areas he/she can enter.
1.
Radiological Buffer Areas (RBAs)
RBAs are intermediate areas which DOE RCS recommends be established to prevent the
spread of radioactive contamination and to protect personnel from radiation exposure. This
area designation is not required by 10 CFR 835 and its use may vary from site to site.
a.
Posting Recommendations:
"CAUTION, RADIOLOGICAL BUFFER AREA"
b.
Recommended requirements for unescorted entry should include:
1)
Appropriate training, such as Radiological Worker I Training.
2)
Personnel dosimetry, as appropriate.
3)
(Insert facility-specific information.)
c.
Recommended requirements for working in RBA
(Insert facility-specific information.)
d.
Recommended requirements for exiting an RBA:
Personnel exiting a RBA containing a Contamination Area, High Contamination Area, or
Airborne Radioactivity Area should, at a minimum, perform a hand and foot frisk.
1)
General guidelines for handheld monitoring using a hand-held radioactive
contamination survey instrument include the following:
a)
Verify the instrument is on, set to the proper scale, and within the calibration
date.
b)
Verify instrument response and source check.
c)
Ensure the audible function of the instrument is on and can be heard.
d)
Determine the instrument background.
(Insert facility-specific information concerning acceptable background rates).
e)
Survey hands before picking up the probe.
f)
Hold the probe approximately " from the surface being surveyed for
beta/gamma and " for alpha radiation.
g)
Move probe slowly over the surface, approximately 2" per second.
