Dosimetry of low-energy protons on the vertical-beam facility at the Munich accelerator.
Various methods of dosimetry for protons with energies up to 25 MeV were compared for radiation fields as might be used in the skin treatment of patients or in biological experiments. The methods used were: Fluence of individually registered protons; Charge deposition in commercially available ionisation chambers; Thermoluminescence detectors, exposed in Munich and evaluated in Krakow; Photometricallly evaluated commercial Fricke dosimeter. An overall agreement within 5% was found between the absolute dose measurements. Depth-dose distributions for Bragg curves measured by a Markus chamber with a depth resolution of 10 micrometers agreed with calculations.
