The cumulative effective dose to astronauts on a typical Mars mission would likely introduce risk exceeding permissible limits for carcinogenesis without innovative strategies for radiation shielding. This is usually done by placing a material that is highly magnetic-resistant in between the source of the magnetic field and the area that needs to be shielded. United States Congress Office of Technology Assessment. Available online: NASA. Shielding from electromagnetic interference is usually accomplished passively by using metal sheets such as copper, aluminum, steel, or metal alloys. These implementations involve a large magnetic field and a large induced electric field. ; Eckersley, S.; Foullon, C.; Guarnieri, V.; Guatelli, S.; Heynderickx, D.; Holmes-Siedle, A.; Lobascio, C.; Masiello, S.; et al. 19 September 1996.

Many passive and active radiation mitigation strategies have been proposed over the past several decades, but the problem remains to be solved. Thus, these studies focused primarily on mass comparisons with passive shielding [, Towards the end of the decade, however, magnetic shielding had almost become a mainstream concept, with active shielding topics dominating discussions at the Special Sessions on Protection Against Space Radiation at the American Nuclear Society meeting in 1967 [, Magnetic shielding development stagnated in the U.S. throughout the 1970s.
