Comparison of AFRRI (Armed Forces Radiobiology Research Institute) and ETCA (Etablissement Technique Central de l'Armament) dosimetry measurements at AFRRI TRIGA (Training Research Isotopes General Atomic) reactor. Technical report
A series of irradiations was performed at the AFRRI TRIGA reactor as the initial step in establishing a dosimetric link between neutron radiobiology research (using high dose rates close to the source) and military applications experiments (using low dose rates farther from the source). A team of physicists from ETCA, part of the French Ministry of Defense, irradiated several personnel dosimeters both free in air (FIA) and at various depths in an anthropomorphic dosimetry phantom. As reference dosimetry, the ETCA group used fission chambers and AFRRI dosimetrists used paired ionization chambers. The kerma rates measured FIA by the two groups with fundamentally different methods showed excellent agreement (within 5%). However, more work is required to resolve some of the difference observed in the in-phantom measurements. The completion of these experiments marks an important first step in relating mixed-field radiobiology studies to potential combat radiation environments.
