CC25 is intended for absolute and relative dosimetry of photon, electron, and proton beams in radiotherapy. Measurements can be performed in air, water phantoms, or solid phantoms. CC25 is a high spatial resolution, small volume chamber. It is waterproof, vented through a waterproof sleeve, and fully guarded.
Used for: Detectors RT
