The 0.6 3Farmer type ionization chamber is suitable for measuring absolute radiation dose of high-energy photon, electron and proton beam. With the dosimeter, we can measure the photon treatment beam produced by the deep X ray therapy machine, the 60Co therapy machine and the medical accelerator and the external irradiation dose of the energy less than 10MeV electron therapy beam.
Product type: atmospheric pressure finger ionization chamber, comply with IEC60731 issued
ionization chamberdosimeter medical electrical standard.
