Abstract:

The dominant source of ionizing radiation in the aerospace environment is galactic cosmic radiation (GCR). Traditionally, calculations of exposure rates for vehicle occupants in aircraft have not included vehicle structure; while in spacecraft, vehicle structure is considered without atmosphere. This report describes modifications applicable to CARI-7 and CARI-7A to allow inclusion of the effects of vehicle structure on calculations of effective dose rate from GCR throughout a suborbital mission in a lightly shielded vehicle (<20 g/cm2). Required coefficients and an example of the technique are provided for aluminum shielding. While results are considerably different than if shielding were entirely neglected, they vary by less than 8% from the simple approximation of 1:1 substitution of additional atmospheric depth for aluminum.
