The CERN-EU high-energy Reference Field (CERF) facility: New FLUKA reference values of spectral fluences, present and newly proposed operational quantities

The CERN-EU high-energy Reference Field (CERF) facility provides an almost unique high-energy workplace radiation field for calibrating and testing radiation protection instrumentation employed at high-energy accelerators and for aircraft and space dosimetry. For the available exposure locations, this work provides the particle fluences of the various components of the radiation field, and a new set of reference values for the currently used operational quantities, i.e. ambient dose equivalent, H*(10), and personal dose equivalent Hp(10), as well as for the newly proposed ICRU/ICRP quantities ambient dose, H*, and personal dose, Hp, that may be adopted in the future for radiation protection. Particle spectra and radiological quantities were computed with the latest versions of the FLUKA code and benchmarked against experimental data taken with one of the reference instruments used at the facility.
