A series of dosimetric measurements was carried out at the Antoni van Leeuwenhoek Hospital, Amsterdam, using a Philips d + T generator, which produced neutrons with energies of approximately 14 MeV. A-150 plastic ionization chambers, an A-150 plastic calorimeter, and a GM dosimeter were used to determine total absorbed dose and the photon absorbed dose fraction. The ion chambers were calibrated in a 60Co gamma-ray field in air and compared in a phantom placed in the 60Co gamma-ray beam. Comparison of the total absorbed dose derived from the ionization chamber measurements to that determined using the calorimeter indicated agreement for the neutron measurements between the techniques to within +/- 2%.
在阿姆斯特丹的安东尼·范·列文虎克医院，使用飞利浦d + T发生器进行了一系列剂量测量，该发生器产生能量约为14 MeV的中子。使用A - 150塑料电离室、A - 150塑料量热计和GM剂量计来确定总吸收剂量和光子吸收剂量分数。电离室在空气中的60Co伽马射线场中进行校准，并在置于60Co伽马射线束中的体模中进行比较。将电离室测量得出的总吸收剂量与用量热计确定的总吸收剂量进行比较，结果表明两种技术在中子测量方面的一致性在±2%以内。
