This FAA- and NASA-sponsored study of cosmic radiation doses recieved by United States residents flying in commercial jet aircraft is the most extensive to date and combines computer calculations with experimental data. Data derived from 1973 statistics on 2.99 million intercity flights carrying 468 million seats were included in the calculations, yielding a total of 581 billion seat-kilometer. The average flight was 1,084 km in length, was flown at an altitude of 9.47 km, and lasted 1.41 h. The average dose rate was 0.20 mrem/h, resulting in an average passenger dose of 2.82 mrem/year and an average crewmember dose of 160 mrem/year. The average radiation dose to the total U.S. population was 0.47 mrem/person/year. These results are in good agreement with data from several experiments performed by us and others in aircraft at various altitudes and latitudes. The significance of these doses to the population is discussed.
这项由美国联邦航空管理局（FAA）和美国国家航空航天局（NASA）赞助的关于乘坐商用喷气式飞机的美国居民所接受的宇宙辐射剂量的研究，是迄今为止最全面的，它将计算机计算与实验数据相结合。计算中纳入了源自1973年299万次城际航班、4.68亿个座位的统计数据，总计5810亿客座公里。平均航班长度为1084公里，飞行高度为9.47公里，持续时间为1.41小时。平均剂量率为0.20毫雷姆/小时，导致乘客平均剂量为每年2.82毫雷姆，机组人员平均剂量为每年160毫雷姆。美国总人口的平均辐射剂量为每年0.47毫雷姆/人。这些结果与我们和其他人在不同高度和纬度的飞机上进行的几项实验数据高度吻合。文中讨论了这些剂量对人群的意义。
