Thimble Ion Chambers
Strict manufacturing tolerances and waterproof construction makes these detectors ideal for dosimetry calibrations in water, air and other phantom materials.
The Exradin Advantage
Waterproof construction backed by five-year warranty.
Rugged Shonka plastic provides years of reliable use and excellent conductivity.
Lack of stem-effect and low leakage provides precise, consistent measurements.
Proven guard design stabilizes measurements and reduces settling time.
Homogeneous material throughout the chamber minimizes perturbation of the beam.
The A19 fits existing plastic phantom cavities and build-up caps, limiting perturbation and minimizing settling time in absolute dosimetry calibration. This chamber is characterized for TG-51 procedures.
Also available in MR compatible version.
