Caprac-t Wipe Test Counter
Capintec's CAPRAC-t® Wipe-Test Counter covers the regulations in 10 CFR Part 35.315 (200 dpm requirements for unrestricted areas and iodine contamination).
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.
