Gamma Ray Ionization Chamber

The CRC®-25W dose calibrator is a sophisticated device that combines the CAPRAC®-R Well Counter and the popular CRC®-25R Dose Calibrator. It offers the necessary speed and accuracy to measure activity and prepare doses. Its ion chamber is a high-pressure well design that has been time-tested by Capintec and is capable of accurately measuring a dose of Tc 99m as high as 6 Ci (250 GBq). The CRC®-25W also boasts chamber plug-and-play capability.

The CRC®-25W enables the user to establish precise counting procedures (protocols) with trigger levels for work, patient, unrestricted areas, and sealed source leak tests during wipe testing. The CRC®-25W is also capable of performing counting functions for wipe tests in as little as 6 seconds at activities as low as 1 nCi. A high-sensitivity Sodium Iodide (NaI) detector is used to measure low activities in a drilled well. The user is also provided with pulse amplitude discrimination by the 6-channel pulse-height analyzer, which can be employed to assist in the identification of radionuclide isotopes.

The CRC®-25W has a menu-driven, push-button interface that is user-friendly and intuitive, combining the chamber and counter. With our remote capabilities, make nuclide and Daily Test selections from a distance of hundreds of feet from the CRC®-25W readout unit.
