title: [1985 dosimetry comparison at 12 radio-oncology centers in Switzerland].
abstract: In 1985 a working group of medical radiophysicists from the Swiss Society for Radiobiology and Radiophysics performed for the second time a dosimetric comparison at 13 irradiation units used in twelve radio-oncologic centres of Switzerland. The dose and dose distribution were measured in a specified target volume in an anthropomorphic phantom, also considering the irradiation planning. On the whole, the results show the expected variations. The average error of positioning towards the specified target volume was 4mm. The differences between the doses calculated for the individual points according to the irradiation scheme and the doses measured in these points amount on an average to less than 5%.
