The Atomlab 100 provides fast, accurate radionuclide activity measurements with performance that easily surpasses the most stringent regulatory requirements.
The unit is simple to operate. There are 13 isotopes selection keys, ten are pre-programmed for the most commonly used radionuclides, and three are user defined. There are 88 isotope - specific dial values listed in the manual, including Y-90 and Sr-89. Any key can be reprogrammed by the user for a desired isotope.
Activity is displayed on a LED readout in either Curie or Becquerel units. Background correction and zero adjustment are performed at the touch of a button. Range selection is automatic.
Activity measurements are performed by a microprocessor controlled electrometer located within the detector assembly of the ionization chamber. The chamber is shielded with .25” (.64 cm) lead. It can be located up to ten feet away from the display unit. Chamber bias is generated within the display unit by an electronic high voltage supply, eliminating the need for expensive battery changes.
The RS-232 port enables the Atomlab 100 Dose Calibrator to communicate with most commercially available nuclear medicine management systems.
Specification:
