For monthly average calculations, databases are used to account for effects of changes in the earth's magnetic field and solar activity on galactic radiation levels in the atmosphere. The output files are typically small (kb), and will slowly get larger if writing the diagnostic output is off.Īs did the previous version of CARI, the program takes into account changes in altitude and geographic location during the course of a flight, based on information provided by the user. The files use approximately 80 MB of disc space and up to 42 MB of RAM. Like previous versions, the program uses a command prompt interface and can be run on most personal computers. The program can run using internal menus or be used in scripts, depending on user selections in the initialization files. Calculations dating to 1958 are possible without providing added data. Particle specific doses, can also be calculated for route or at specific locations. The program will accommodate both waypoint defined and shortest route (geodesics) flight paths.

The CARI-7 computer program, developed at the FAA's Civil Aerospace Medical Institute, calculates the effective dose of galactic cosmic radiation received by an individual (based on an anthropomorphic phantom) on an aircraft.
