Module 6: Radiological Access Controls and Postings
Instructor's Notes
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.
h)
If the count rate increases during frisking, pause for 5
to 10 seconds over the area to provide adequate time
for instrument response.
2)
Alarm response for hand-held survey instrument
a)
If contamination is indicated, remain in the area and
notify the Radiological Control personnel.
b)
Minimize cross contamination. For example , put a
glove on a contaminated hand while waiting for the
Radiological Control personnel to arrive.
3)
Portal monitors
(Insert facility-specific information.)
2.
Radiation Areas (RAs)
E05 Define the areas
controlled for radiological
RAs are any areas accessible to individuals in which
purposes.
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.
