Information Needed to Make Radiation Protection Recommendations for Space Missions Beyond Low-Earth Orbit. NCRP Report No
153. National Council on Radiation Protection and Measurements (2006).
The purpose of this Report is to identify and describe information needed to make radiation protection recommendations for space missions beyond low-Earth orbit (LEO). Current space radiation guidelines pertain only to missions in LEO and are not considered relevant for missions beyond LEO. Radiation protection in deep space is complicated because of the unique nature of the space radiation environment, which is unlike any radiation environment present on Earth or in LEO.INTRODUCTION
