The CRC-15 ßETA combines the most popular dose calibrator (CRC-15R) and our beta counter achievement (ßETA Enhanced) into one convenient, complete system. The simplicity, speed and accuracy of the CRC-15R has now been carried to a new level offering two detectors that cover the widest range of nuclides giving the same accuracy to beta counting that is demanded of gamma counting.

This intelligent system changes detectors with the push of one key and is always ready to count with either detector. The CRC-15 ßETA’s advanced system allows selection of over 86 nuclides with their half-lives simply by typing the nuclide name/number and pressing ENTER. This sets the system up for accurate counting of the nuclide selected. This functions for both gamma and beta counting.

For facilities using high energy beta nuclides such as Sr-89 or P-32 the CRC-15 ßETA assays syringes or vials giving results in Becquerels or Curie units. The system is designed to store over 100 nuclides in its memory and for more than 20, the user can specify container effect compensation while defining calibration factors. This system is perfect for those facilities that want a precise, accurate, reliable, quick and simple way to count both gamma and beta nuclides. With its built-in auto-calibration, QC programs and system test, the CRC-15 ßETA allows the use of one complete system to do the work of two counting systems and at a cost that says VALUE.
