Exradin® W2 Scintillator System
Unlike other detector types, the water equivalent W2 scintillator does not perturb small field dose distributions when it is placed in the beam, so you can measure small fields with greater accuracy.

Exradin® W2 Scintillator System Overview
- AAPM/IAEA TRS 483 states the scintillator is the only detector with a kQ of 1.000, making the W2 the ideal SRS detector.
- All corrections are built in.
- Water equivalent.
- Inherently waterproof.
- Can be used for both water scanning and point dosimetry.
- User replaceable fiber, includes both 1x1 mm and 1x3 mm.
- No dose rate, temperature, or energy dependencies.
- The W2 system features Čerenkov corrected measurement signals that can be converted to a proportional analog output, which can be read by any electrometer. This allows the W2 system to be connected to a water phantom system for scanning.
