Aircrew members and passengers are exposed to increased rates of cosmic radiation on-board commercial jet aircraft. The annual effective doses of crew members often exceed limits for public, thus it is recommended to monitor them. In general, the doses are estimated via various computer codes and in some countries also verified by measurements. This paper describes a comparison of three cosmic rays detectors, namely of the (a) HAWK Tissue Equivalent Proportional Counter; (b) Liulin semiconductor energy deposit spectrometer and (c) TIMEPIX silicon semiconductor pixel detector, exposed to radiation fields on-board commercial Czech Airlines company jet aircraft. Measurements were performed during passenger flights from Prague to Madrid, Oslo, Tbilisi, Yekaterinburg and Almaty, and back in July and August 2011. For all flights, energy deposit spectra and absorbed doses are presented. Measured absorbed dose and dose equivalent are compared with the EPCARD code calculations. Finally, the advantages and disadvantages of all detectors are discussed.
商业喷气式飞机上的机组人员和乘客会受到更高剂量的宇宙辐射。机组人员的年有效剂量常常超过公众剂量限值，因此建议对他们进行监测。一般来说，剂量是通过各种计算机代码估算的，在一些国家还会通过测量进行验证。本文描述了三种宇宙射线探测器的比较，即(a) HAWK组织等效正比计数器；(b) 柳林半导体能量沉积谱仪；(c) TIMEPIX硅半导体像素探测器，它们在捷克航空公司的商用喷气式飞机上接受辐射场照射。测量在2011年7月和8月从布拉格飞往马德里、奥斯陆、第比利斯、叶卡捷琳堡和阿拉木图并返程的客运航班上进行。给出了所有航班的能量沉积谱和吸收剂量。将测量的吸收剂量和剂量当量与EPCARD代码计算结果进行比较。最后，讨论了所有探测器的优缺点。
