7. Nuclear Pharmacy
Nuclear pharmacy, also known as radiopharmacy, involves preparation of radioactive materials
for patient administration that will be used to diagnose and treat specific diseases in nuclear
medicine. The Atomlab 500 system is used to verify the radioactivity of a radionuclide before
administration to the patient.

The Nuclear Pharmacy screen serves as the main menu for this section of the system. From this
screen, any of the four Nuclear Pharmacy procedures can be accessed:

Moly Assay (Moly Breakthrough)
The Moly Assay test measures the amount of Mo-99 in a syringe or vial of Tc-99m. To execute
this test, an empty Moly Shield is used to perform a background count. The syringe or vial of
Tc-99m is added to the Moly Shield. A count is taken for the activity of the Moly counted
through the lead Moly Assay Shield. The vial or syringe is then removed from the lead shield
and placed into the dose calibrator. The system calculates the activity of Moly and the
µ Ci of
Moly per mCi of Tc-99m.
If the Moly concentration is above the regulatory limit of 0.15
µ
Ci of Mo-99 per mCi of Tc-99m,
the number is shown in red.
