For use in all air kerma, absorbed dose, and exposure measurements



The MAGNA 1cc Parallel Plate Chamber is a vented and fully guarded ion chamber ideally suited for mammography and general diagnostic energy X-ray regions, with the appropriate calibration.

The nominal calibration factor for various applications using the MAGNA 1cc Parallel Plate Chamber is 3 R/nC ± 3% over the entire diagnostic range; it is within ± 1% between the half value layers of 0.2 mm Al to 0.5 mm Al of the mammography range.



The MAGNA 1cc Parallel Plate Chamber is constructed of rugged C552 Shonka air-equivalent plastic, providing excellent conductivity and years of reliable use.



  • Exceptionally wide guard ring, 4.7 mm, yields stable, precise measurements and minimizes settling time by creating uniform field lines
  • Chamber support rings, collector and guard are made of durable, long lasting Shonka conductive plastic; use of homogeneous material throughout the chamber minimizes perturbation of the beam due to the presence of the chamber and optimizes measurements
  • Chamber window material is conductive Kapton film of 0.001 inch thickness (3.86 mg/cm2)
  • Cable terminates in a standard, triaxial BNC connector; other cable connectors and adapters are available upon request
  • Chamber has a vent hole to maintain the internal air at ambient atmospheric pressure
  • Non-removable, rigid, one piece stem allows for easy, accurate positioning
  • Collecting column is 1.0 cc
