Exradin Parallel Plate Chambers ensure precision in depth-dose measurements by providing uniform field lines even at low energies.

 

Exradin A10 Ion Chamber

The A10 chamber provides excellent spatial resolution for dose distribution measurements in a water phantom. An acrylic waterproof cap is included with this chamber for use in TG-51 electron beam protocols.

 

Exradin A11 Ion Chamber

Waterproof A11 chamber may be operated while fully submerged without any protective sheath; ideal for repeated TG-51/TRS-398 dose distribution measurements in a water phantom.

 

Exradin A11TW Ion Chamber

The A11TW is tailored for use in superficial therapy and low energy diagnostic beams. The thin-window design provides nearly constant response over the entire diagnostic energy range.

 

Exradin A20 Ion Chamber

The A20 is a low-energy x-ray chamber for assessing and calibrating pinpoint radiation fields for x-rays, stereotactic and TG-61 compliant superficial skin therapy.
