A review of the state of our knowledge of the geomagnetic field in space and of energetic charged particles trapped or guided by this field. One of the more interesting findings is that, in regions of trapped radiation, the dosages that a human would receive during periods of great sun-spot activity exceed the limits of human safety. Although moderate shielding will not completely nullify the hazards during these rare periods of intense solar activity, the chances are several thousand to one that it will be sufficient on any given day.

This report is part of the RAND Corporation Research memorandum series. The Research Memorandum was a product of the RAND Corporation from 1948 to 1973 that represented working papers meant to report current results of RAND research to appropriate audiences.

Our mission to help improve policy and decisionmaking through research and analysis is enabled through our core values of quality and objectivity and our unwavering commitment to the highest level of integrity and ethical behavior. To help ensure our research and analysis are rigorous, objective, and nonpartisan, we subject our research publications to a robust and exacting quality-assurance process; avoid both the appearance and reality of financial and other conflicts of interest through staff training, project screening, and a policy of mandatory disclosure; and pursue transparency in our research engagements through our commitment to the open publication of our research findings and recommendations, disclosure of the source of funding of published research, and policies to ensure intellectual independence.
