自1998年以来，基于PADC（聚烯丙基二甘醇碳酸酯）的中子剂量测定是在PSI使用所谓的原始Paul Scherrer研究所（PSI）设计完成的。最初的设计（即保持器）后来进行了更改。这两种设计都针对高能加速器周围的工作场所进行了优化，其中中子能谱主要由高达约100 MeV的快中子控制。除了剂量计设计的变化之外，还引入了基于显微镜扫描技术的新评估方法，并优化了蚀刻条件。在目前的工作中，与原始的和新的剂量计设计获得的响应进行了比较的领域的放射性核素源和单能参考字段使用新的评价方法。建立了正常入射中子个人剂量当量响应曲线与入射中子能量的函数关系。
Since 1998 neutron dosimetry based on PADC (poly allyl diglycol carbonate) is done with a so-called original Paul Scherrer Institute (PSI) design at PSI. The original design (i.e. holder) was later changed. Both designs are optimised for use in workplaces around high-energy accelerators, where the neutron energy spectra are dominated by fast neutrons ranging up to some 100 MeV. In addition to the change of the dosemeter design a new evaluation method based on a microscope scanning technique has been introduced and the etching conditions have been optimised. In the present work, the responses obtained with the original and the new dosemeter designs are compared for fields of radionuclide sources and monoenergetic reference fields using the new evaluation method. The response curves in terms of the personal dose equivalent for normally incident neutrons were built as functions of the incident neutron energy.
