Phantom Dosimetry for TRIGA Reactor Irradiations in Chair and Wheel Arrays
Abstract
Behavioral effects of reactor radiation on rhesus monkeys (Macaca mulatta) studied at AFRRI over the last 2 decades form an essential data base in development of combat casualty criteria for the armed forces of the United States and NATO. Through the course of the AFRRI studies, the irradiation techniques and the dose specification procedures differed, making difficult the complete intercomparability of results. A series of phantom dosimetry measurements completed in 1979-1980 have now been compiled to allow the interconversion of midhead and midthorax doses as well as free-in-air kerma at the midhead and midthorax locations. Included in the compilation are data for different reactor shield configurations and for both the visual discrimination task chair array and the physical activity wheel array. In addition to total- dose comparisons, the compilation includes data on neutron-to-gamma dose ratios free in air and at depth. Results of this work facilitate the more accurate retrospective analysis of AFRRI data on the behavioral effects of reactor radiations.
