Primary standards for absolute measurement of absorbed dose in proton beams are not yet established at national standards laboratories. At present, calibrations are performed by indirect procedures based on the air-kerma standards for Co-60 gamma ray. Different methods are being investigated for absolute dosimetry of proton beams. These include water calorimetry, ionization chamber dosimetry and proton fluence measuring methods (e.g. Faraday cup or activation methods). Any of these methods has advantages and drawbacks. Water calorimetry is certainly the most promising procedure for absolute dosimetry, even if some problems should be still overcome also in this type of measurement. An outline of the above methods is presented together with a comparative analysis.
