Title Issues in space radiation protection: Galactic cosmic rays
Bibliographic information Jan. 1995, Vol.68, No.1, p.50-58. Illus. 28 ref.
Abstract There is limited knowledge concerning the physical properties of and biological responses to cosmic rays. Herein, the current status of space shielding technology and its impact on radiation protection is discussed in terms of conventional protection practice and a test biological response model. The impact of biological response on optimum materials selection for cosmic ray shielding is presented in terms of the transmission characteristics of the shield material. Although liquid hydrogen is an optimum shield material, it is difficult to use. The evaluation of the effectiveness of polymeric structural materials as a substitute must await improvement in our knowledge of both the biological response and the nuclear processes.
