0.6cc finger ionization chamber

       0.6cm3Farmer finger-type ionization chamber can be used for high-energy photon, electron, proton beam absolute radiation dose measurement. With the use of dosimeter, it can measure the photon treatment beam generated by X-ray deep treatment machine, 60Co treatment machine and medical accelerator, and the external radiation dose of the electron treatment beam with energy less than 10MeV.
