CAPRAC-t Well Counter

CAPRAC t Well Counter copy

Don't worry about meeting the regulations in 10 CFR Part 35.315 (200 dpm requirements for unrestricted areas and iodine contamination). Capintec's CAPRAC-t Wipe-Test Counter handles all of them.

Measure for measure, no other well counter offers the speed, accuracy and complete range of built-in features provided by the compact CAPRAC-t. It performs a wipe test in just 6 seconds (for 1 nCi) and detects extremely low levels of activity with the accuracy only a NaI drilled-well detector can provide.

The CAPRAC-t can also serve as a single-well gamma counter in departments that do not need multi-sample changers. User-defined protocols, trigger levels, and counting times are a "snap". A 256-channel pulse-height analyzer permits built-in gamma spectroscopy. Definable conversion factors for specific radionuclides allow the CAPRAC-t to calculate results in cpm, dpm, nCi, cps, dps, or kBq. The CAPRAC-t also displays photon-energy histograms.

The CAPRAC-t is engineered and built for years of consistent, reliable performance and is Curie or Becquerel selectable. The unit has automatic background subtraction and self-diagnosis programs for systems testing with optimized signal-to-noise ratio. It includes a lead outer shield (1.3 cm thick) with optional auxiliary shield available.

Well Autocalibrate 

Calibration with Cs137 sets the voltage gain and establishes the FWHM for the detector using both the 32.5 kev and 662 kev peaks. Linearity correction with Eu152 applies correction factors for the non-linear response of NaI crystals to different kev’s detected by the crystal. This results in accurately centered peak detection for different nuclides.

Sample Measurement

Isotope peaks found in sample measurements are compared to data in the isotope library to assist the user in the identification of the specific nuclide.
