WebAlanine samples for the ESR/alanine dosimetry were made on the basis of crystalline alanine with an admixture of 20% paraffin. For calibration of the ESR/alanine dosimeters, a standard field of cobalt-60 gamma radiation was used, with a field size of 10x10cm2. The alanine samples are cylindrical shaix* 5mm diameter and 10mm in length. For ...
WebPassive alanine dosimeters were shown to have a linear response with the DPP up to at least 2.4 Gy/pulse, but there is no real-time read-out. The alanine system was used, however, as reference to determine the ion recombination correction for an Advanced Markus plane-parallel ionization chamber, studied as a possible real-time dose monitor at ...
