Verify instrument response and source check.
Ensure the audible function of the instrument is on
and can be heard.
Determine the instrument background.
(Insert facility-specific information concerning
acceptable background rates).
Survey hands before picking up the probe.
Hold the probe approximately ½" from the surface
being surveyed for beta/gamma and ¼" for alpha
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.
Alarm response for hand-held survey instrument
If contamination is indicated, remain in the area and
notify the Radiological Control personnel.
Minimize cross contamination. For example, put a
glove on a contaminated hand while waiting for the
Radiological Control personnel to arrive.
(Insert facility-specific information.)
Radiation Areas (RAs)
E05 Define the areas
controlled for radiological
RAs are any areas accessible to individuals in which
radiation levels could result in an individual's
receiving a deep dose equivalent in excess of 5
mrem/hr. This is established based on dose rates at
30 cm from the source of radiation.
