The results of measurements with neutron energies up to 60 MeV are shown for the personal neutron dosemeters Thermo Electron EPD-N2, ALOKA PDM-313 and the PTB prototype dosemeter DOS-2002. All dosemeters show dose equivalent responses that are about a factor of 10, too high at 60 MeV. A new prototype dosemeter-called DOS-2005-consisting of a detector with a thin effective layer of 6 microm has been set up at PTB. The dose equivalent response of this dosemeter and that of the newly developed dosemeter SAPHYDOSE-N was measured up to 19 MeV. Both dosemeters indicate a more flat response at high neutron energies. Further needs-optimisations, measurements and calculations-for use at high-energy accelerators and in space are discussed.
给出了热电子公司的个人中子剂量仪EPD-N2、阿洛卡公司的PDM-313以及PTB原型剂量仪DOS-2002在高达60 MeV中子能量下的测量结果。所有剂量仪的剂量当量响应在60 MeV时都高出约10倍。PTB已研制出一种新的原型剂量仪——称为DOS-2005，它由一个有效层厚度为6微米的探测器组成。测量了该剂量仪以及新研制的剂量仪SAPHYDOSE-N在高达19 MeV时的剂量当量响应。两种剂量仪在高中子能量下都显示出更平坦的响应。还讨论了在高能加速器和空间应用方面进一步的需求——优化、测量和计算。
