Farmer® Ionization Chamber 30012
Farmer chamber with graphite wall for reference dosimetry in high-energy photon, electron and proton beams
The 30012 Farmer chamber is intended for reference dose measurements in radiation therapy. Correction factors needed to determine absorbed dose to water or air kerma are published in the pertinent dosimetry protocols. The graphite wall makes the chamber almost water equivalent, the aluminum central electrode improves the energy response at energies below 60Co. The chamber is intended for the use in solid state phantoms and therefore not waterproof.
- Graphite wall
- Aluminum central electrode
