Monitoring Cosmic Radiation Risk: Comparisons Between Observations and Predictive Codes for Naval Aviation

Abstract

Utilizing a unique, Far West Technology Tissue Equivalent Proportional Counter (TEPC)-based system called the HAWK, the atmospheric radiation exposures of commercial air travelers and naval personnel were compared to the quantity predicted by commercially available radiation codes. The HAWK simulates a two micron-diameter somatic cell, measuring the lineal energy, absorbed dose, and dose equivalent based on the International Commission on Radiological Protection (ICRP)-60 recommendations. Prior to the flights, the HAWK detector response was modeled with MCNP5 and GEANT4. Later, the data were analyzed both to produce a dose rate as well as a total dose for the flight s duration.
