Micro Ion Chambers

Superior small-field dosimetry to assess pinpoint radiation in IMRT, stereotactic, orthovoltage, x-rays and superficial skin therapy.

The Exradin Advantage.

  • Inherently waterproof construction eliminates the need for sleeves or protective coatings.
  • Rugged conductive plastic provides years of reliable use.
  • Lack of stem-effect and low leakage provides precise, reliable measurements.
  • **NEW**  We now offer MR-Compatible Ion Chambers.

Exradin A16 Ion Chamber

The Model A16 microchamber measures extremely small field sizes, allowing for exceptional spatial resolution and exact pinpoint beam profile characterization. These attributes make the A16 ideal for stereotactic radiosurgery and IMRT applications.

The A16 microchamber is the smallest ION chamber in the world.
