1. Introduction
Intended Use
The Atomlab Dose Calibrator is intended to measure the activity of a radioactive source of a
known isotope. This measurement may be for purposes of determining or verifying a
radiopharmaceutical dose for nuclear imaging or nuclear medicine. This measurement may also
be for the purpose of determining the radioactivity of a sample for dose calibrator constancy
and Accuracy Testing or to measure other non-medical radioactive samples.
Indications for Use
The Atomlab Dose Calibrators are used in nuclear medicine departments, clinics, and nuclear
pharmacies to measure radioactive doses for administration to patients. The system is used to
verify the radioactivity of a radionuclide before administration to the patient.
Atomlab Dose Calibrators use an argon gas filled pressurized detector to measure the activity
of a radionuclide source of a known isotope. Their primary application is the measurement of
the dose administered to a patient in nuclear imaging or nuclear medicine. Additionally, there
are advanced, but easy-to-use programs for Nuclear Pharmacy.

values on a touch-screen display.
The system consists of a low pressure ionization chamber, electrometer with extraordinary
linearity, and an auto-ranging touch-screen color display. It provides fast, accurate radionuclide
measurements with performance that easily complies with the most stringent regulatory
requirements.
Activity measurements are performed by the microprocessor-controlled electrometer located
within the chamber assembly. The chamber is shielded with .25" (6.3 mm) lead. It can be
located up to three feet away from the display unit. The unit is shipped with a three foot cable,
but eight foot and 18 feet cables are available. Chamber bias is generated by an electronic
