242 ATOMLAB 500 DOSE CALIBRATOR
Records and Maintenance
Records
Article 10 CFR 35.2060 requires that a
NRC licensee maintain instrument
qualification records for 3 years. The
records must include the model and
serial number of the instrument, the
date of the qualification, the results of
the qualification, and the name of the
individual who performed the
qualification.
Dipper and Well Liner
Inspect the instrument on a quarterly
basis to ascertain that the well liner is in
place and is not damaged. Check for
contamination of the liner and dipper as
follows:
1 Remove the plastic dipper and liner
from the well chamber.
2 Press the Zero Background (Bkgnd)
button to zero the calibrator.
3 Put the liner back in. If the display
reading increases, the liner may be
contaminated.
4 If the liner is OK, put the dipper back
in and check for contamination.
5 If any part is contaminated, you
must decontaminate or replace the
item and then recheck for
contamination.
Dial Value Checks—Monthly
Each isotope button is programmed
with a specific dial value (DV). The user
can adjust the DV for a particular need.
Each isotope button should be checked
periodically to verify it is set to the
correct dial value for that isotope. The
method of displaying the dial values
varies by model; consult the operation
manual for your dose calibrator to see
how to display the dial values.
NOTE: The Dial Value check is to verify
that no one has accidentally changed
the Dial Value from the factory settings
or the appropriately determined facility
settings.
Repair or Replacement
Consider repair or replacement, if the
dose calibrator falls outside the
suggested tolerances.
If repair or replacement is required,
contact Biodex Medical Systems for
instructions
