0.6cc finger ionization chamber
The 0.6cm3Ferer finger ionization chamber is suitable for absolute radiation dose measurement of high-energy photons, electrons and protons. Used with a dosimeter, it can measure photon therapy beams generated by deep X-ray machines, 60Co treatment machines and medical accelerators, and external irradiation doses of energy less than 10 MeV electronic treatment beams.
