title: Dosimetry of 70 MeV proton beams from the NIRS cyclotron.
abstract: Dosimetry of 70 MeV proton beams for radiotherapy was carried out using various ionization chambers. The beam irradiation conditions, dose estimation with an ionization chamber, measurement of dose distributions, and calculation of isodose curves for the proton beams will be discussed.
