Radiation Therapy
Farmer-type ionization chambers are used for absolute dosimetry of photon, electron, and proton beams, as well as depth dose and field profile measurements.
The FC65-G chamber is for reference dosimetry and calibrations, while FC65-P is for daily machine checks and routine applications. These chambers work with medical accelerators, X-ray beams (≥70 kV), gamma radiation (¹³⁷Cs, ⁶⁰Co), and proton beams (50–250 MeV). Also, FC65-G is MRI linac compatible.
