Schedule a one-on-one at no charge [5] [5]Proven performance for fast, accurate measurements.

The Atomlab 500 can be used for a wide variety of nuclear medicine, PET and radioimmunotherapy applications, with proven performance for fast, accurate measurements. The system consists of a low pressure ionization chamber, electrometer with extraordinary linearity, and an auto-ranging color touchscreen display. Additionally, there are advanced, but easy-to-use programs for nuclear pharmacy.

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 eight feet away from the display unit. Chamber bias is generated by an electronic high voltage supply, eliminating the need for expensive battery changes.

Every element of the design and technical development will increase dose accuracy, department productivity and regulation compliance. The attractive and intuitive human interface guides the user through each operation. Software can easily be updated via the Biodex website or by using a convenient USB memory device.

In addition to powerful self-diagnostics, the Atomlab 500 includes an exclusive chamber monitoring technology to ensure longer life and accuracy. Integrated pressure and temperature sensors feedback data so that the influence of gas pressure change will not affect an accurate reading.


The system is easy to use. There are 12 isotope selection touch keys pre-programmed for the most commonly used radionuclides. Any of those keys can be reprogrammed by the user for a desired isotope. There are 98 isotope-specific dial values listed in the library. Dial values can easily be changed if required.

Activity is displayed on the color display in either Curie or Becquerel units. Background correction is performed at the touch of a button. Range selection is automatic, from .01 microcurie to 100 Curies of Tc-99m or 25 Curies of F-18.

Quality Assurance

The Atomlab 500 has been designed to make life easier. The extensive selection of quality assurance applications streamlines and simplifies hot lab administration requirements. The system stores and decay corrects multiple reference sources and compares the measured activity to the calculated activity for the daily constancy test.

Linearity tests can be performed in the traditional manual method or by a fully automated program that allows for readings from a source to be taken, and automatically recorded at specified intervals. The system will graph the results.

The attenuation tube test for linearity can be performed using software that will guide the user through the procedure, store the values and make all calculations.


Atomlab Dose Calibrators have a reputation for being extremely accurate.  Biodex and chamber manufacturer Sun Nuclear Corporation have participated in the isotope program sponsored by National Institute of Standards and Technology. Each month a certified isotope is received from National Institute of Standards and Technology and is measured in the Atomlab™ Dose Calibrator, producing direct traceability to National Institute of Standards and Technology.

Commercial Nuclear Pharmacy

The Atomlab 500 Dose Calibrator features a nuclear pharmacy "Dose Calculation Screen" to meet the needs of a commercial nuclear pharmacy. All the information needed to draw doses efficiently is readily available on one screen. The feature easily performs pre- and post-decay calculations, volume calculations for specific times and isotope changes all with minimal screen touches. No calculators needed! Atomlab Dose Calibrators can read up to 100 Curies of Tc-99m, thereby eliminating the need for an aliquot preparation, a significant time saver every time a generator is milked.


Ethernet and serial port to communicate with most commercially available nuclear medicine management systems. USB connectivity for external monitor, printer and software upgrades.

Features Include:

  • A “zero background” feature allows users to configure system background count time for 30, 60 or 100 seconds. This feature changes the counting time when selecting the “zero background” button in all functions, including the Moly Assay application.
  • Isotope libraries in both the dose calibrator and wipe test counter include Lu-177 and
    Ra-223 isotopes. Libraries include updated dial values, isotope ROIs and efficiency settings.
  • Half-Life Verification App included in the nuclear pharmacy menu. Simply select the isotope, choose two or three readings for the calculation, and set the time between readings. The results show the calculated half-life and the variance to the real half-life for the selected isotope.
