Reference dosimetry for various Health Physics Research Reactor spectra

Reference neutron dosimetry is developed in a consistent and reproducible manner for five different Health Physics Research Reactor (HPRR) spectra: the unshielded HPRR, the HPRR shielded by 20-cm concrete, by 12-cm Lucite, by 13-m steel, and by a 5-cm steel/15-cm concrete shield. The reference dosimetry is presented in two forms so as to be of maximum usefulness both to dosimetrists and to reactor operations personnel. The forms are: (1) dosimetric data (i.e., wet tissue kerma, element 57 dose, and element 57 dose equivalent) per unit fluence at 3 m from the centerline of the HPRR, and (2) dosimetric data at 3 m from the centerline of the HPRR per fission in the reactor. A large amount of HPRR dosimetry-related information are included and form a comprehensive compilation of available data. These data include calculated HPRR neutron energy spectra for each of the five above mentioned shielding situations, dosimetric data per unit fluence as a function of neutron energy, dosimetric contributions to the total reference values by neutron energy group, quality factors, shield attenuation factors and a summary of nuclear engineering data for each shield, kerma variation with distance from the HPRR, and a summary of previously published reference dosimetry-related HPRR data.
