An intercomparison of absorbed dose from high‐energy electron beams using Fricke dosimetry at four radiotherapy centers in the north of Taiwan is described. Two water phantoms of 30×30×30 cm 3 and a number of Fricke dosimeters were used at each center. The dosimeters were irradiated to an absorbed dose of approximately 45 Gy (4500 rad) at different electron energies. The measurements, calibration procedures, and the factors affecting the response of the dosimeters are discussed. The results of the intercomparison of the four centers are given in detail.
