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.

If the count rate increases during frisking, pause for 5
to 10 seconds over the area to provide adequate time
for instrument response.
