The annual effective doses of aircrew members often exceed the limit of 1 mSv for the public due to the increased level of cosmic radiation at the flight altitudes, and thus, it is recommended to monitor them [International Commission on Radiation Protection. 1990 Recommendations of the International Commission on Radiological Protection. ICRP Publication 60. Ann. ICRP 21: (1-3), (1991)]. According to the Monte Carlo simulations [Battistoni, G., Ferrari, A., Pelliccioni, M. and Villari, R. Evaluation of the doses to aircrew members taking into consideration the aircraft structures. Adv. Space Res. 36: , 1645-1652 (2005) and Ferrari, A., Pelliccioni, M. and Villari, R. Evaluation of the influence of aircraft shielding on the aircrew exposure through an aircraft mathematical model. Radiat. Prot. Dosim. 108: (2), 91-105 (2004)], the ambient dose equivalent rate Ḣ*(10) depends on the location in the aircraft. The aim of this article is to experimentally evaluate Ḣ*(10) on-board selected types of aircraft. The authors found that Ḣ*(10) values are higher in the front and the back of the cabin and lesser in the middle of the cabin. Moreover, total dosimetry characteristics obtained in this way are in a reasonable agreement with other data, in particular with the above-mentioned simulations.
由于飞行高度处宇宙辐射水平增加，机组人员的年有效剂量常常超过公众1毫希沃特的限值，因此，建议对他们进行监测[国际辐射防护委员会。《国际辐射防护委员会1990年建议》。ICRP第60号出版物。《国际辐射防护委员会年报》21: (1 - 3)，(1991)]。根据蒙特卡罗模拟[巴蒂斯托尼，G.，法拉利，A.，佩利乔尼，M.和维拉里，R.考虑飞机结构对机组人员剂量的评估。《空间研究进展》36: ，1645 - 1652(2005)以及法拉利，A.，佩利乔尼，M.和维拉里，R.通过飞机数学模型评估飞机屏蔽对机组人员暴露的影响。《辐射防护剂量学》108: (2)，91 - 105(2004)]，环境剂量当量率Ḣ*(10)取决于飞机内的位置。本文的目的是通过实验评估选定类型飞机上的Ḣ*(10)。作者发现，Ḣ*(10)值在客舱前部和后部较高，在客舱中部较低。此外，以这种方式获得的总剂量学特征与其他数据合理吻合，特别是与上述模拟结果。
