Features
Don’t worry about meeting the new regulations in 10 CFR Part 35.315 (200 dpm requirements for unrestricted areas and iodine contamination). Capintec’s CAPRAC 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. 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 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 6-channel pulse-height analyzer permits built-in gamma spectroscopy. Definable conversion factors for specific radionuclides allow the CAPRAC to calculate results in cpm, dpm, nCi, cps, dps, or kBq. The CAPRAC also displays photon-energy histograms.
The CAPRAC 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.
