DOSIMETRY IN THE MANNED SPACE PROGRAM.

The dosimetric results of the various U. S. manned spaceflight programs are presented including a brief description of the trapped radiation and spacecraft shield models, instrumentation, and a comparison of computed and measured radiation doses. It was determined that reasonably good agreement exists between the computed and measured doses, and was based on an assessment of the nominal environment. The measured crew doses were well below the mission operational dose limits established by NASA upon recommendation of the Space Science Board. The Natural Environment Support Concept in being established to provide flight support personnel with solar and space environment data.
