FUNCTIONAL DESCRIPTION
The CRC
®
-712MH Radioisotope Dose Calibrator provides a precise, accurate, fast and very
convenient method of measuring the activity of a radioisotope sample or radiopharmaceutical
dose at the time and place of its application.
The CRC
®
-712MH Radioisotope Does Calibrator has been specifically designed for high
activity radioisotopes measurements which are required for P.E.T centers, for
radiopharmaceutical applications, research or other related activities.
When a sample of a known radioisotope or radiopharmaceutical dose is placed in the
chamber well in the appropriate geometry and the proper calibration number is set, the
activity of the sample will be displayed with the proper units on the Readout unit.
Note: For a detailed description of the basic principles of the calibrator, see to APPENDIX I:
PRINCIPLE OF THE CALIBRATOR.
FEATURES
•
Activity measurements are performed by state of the art electronic circuits in
conjunction with a one atmosphere ionization chamber possessing extremely high
sensitivity and stability.
•
Curie or Becquerel units of measurement are selected by a rotary switch that can be
locked in either position.
•
An 8-button measurement range switch provides unambiguous manual selection or
automatic selection of 6 activity measurement ranges. Manual range selection
provides the shortest measurement time when numerous measurements are being
taken in the same activity range. Automatic range selection provides the fastest
measurement when the activity range of the sample is not known.
•
Extra large 4-digit numeric readout display with a floating decimal point: 0.8” high (20
mm.). Back-lighted units of measurement symbols.
•
Eight preset push-buttons are provided for quick selection of the calibration number of
the most often used radioisotopes. The assignment of any of the eight push-buttons
may be changed by the user for his or her particular requirements.
•
Confirmation of the instrument functions and all the required adjustments can be
made with fingertip operation. (Zero, Background, Bias Test)
