Our Research Focus
The Radiobiology Research Team performs research on the effects of ionizing and non-ionizing radiation on living systems, identifies radiation hazards in the aviation environment, and studies methods of protection from such hazards.
The CARI-6 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 flying the shortest route (a geodesic) between any two airports in the world. The program takes into account changes in altitude and geographic location during the course of a flight, as derived from the flight profile entered by the user.

The CARI-6 and CARI-6M programs, shown below, are 16-bit programs, so a DOS emulator is required if running CARI-6 on new systems which do not support DOS. We do hope to have 32- and 64-bit versions of CARI (CARI-7) early in 2016.
