A summary of present knowledge of solar-flare radiation, one of the major hazards to manned space flight. Areas are listed in which more experimental data are needed to accurately compute the shielding requirements for space vehicles. Some frequently quoted estimates of the weight of adequate shielding have been prohibitively high. However, this memorandum shows that these estimates may be three to six times larger than necessary. It is concluded that appropriately designed experiments in the space research program can help to eliminate the ambiguities in shielding calculations.
