56.The label on an unopened vial states that the vial contains 10
mL of RPH with a concentration of 55.5 MBq/mL. When the
technologist assays the vial in a dose calibrator, it measures 9 mCi.
Which of the following actions should the technologist perform
first?
a.check the radionuclide setting on the dose calibrator
b. begin to prepare unit doses from the vial
c. perform an accuracy check on the dose calibrator
d. contact RPH manufacturer

, a. category 1
category 1 (1m) <0.5 and (surface) no detectable radiation
category 2 (1m) <50 and (surface) <1.0
category 3 (1m) <200 and (surface) <10
d. reduce the chromate ion to a lower valance state
a. the patient rebreathe a mixture of xenon and oxygen during the wash-in phase
a. check the radionuclide setting on the dose calibrator
