TAILIEUCHUNG - Radiation Protection Guidance for Activities in Low-Earth Orbit

Preface This is the second National Council on Radiation Protection and Measurements (NCRP) report that provides radiation protection guidance for astronauts working in low-earth orbit. The guidance in this Report supercedes the radiation exposure limit recommendations provided in NCRP Report No. 98 that was published in 1989. Readers may find some of the radiobiological information in Report No. 98 to continue to be relevant and of interest and, therefore, Report No. 98 will continue to be available from NCRP Publications. This work has been performed at the request of the National Aeronautics and Space Administration (NASA) and NCRP gratefully acknowledges NASA's support | NCRP Report No. 132 Radiation Protection Guidance for Activities in Low-Earth Orbit Recommendations of the NATIONAL COUNCIL ON RADIATION PROTECTION AND MEASUREMENTS Issued December 31 2000 National Council on Radiation Protection and Measurements 7910 Woodmont Avenue Suite 800 Bethesda Maryland 20814 LEGAL NOTICE This Report was prepared by the National Council on Radiation Protection and Measurements NCRP .
