The update to ISO 8529-1 (2021) reduces the variety of neutron fields from sources. For neutron metrology, it is crucial to have a standard radiation field with known fluence and energy well-defined. This study focuses on analyzing new energy ranges and characterizing moderated neutron fields, emphasizing the importance of low-energy neutrons and their impact on dose assessment. Experiments and simulations were conducted with the moderation of the 241AmBe source in light water, enabling the characterization of a new moderated spectrum and the presentation of reference values for physical and radioprotection quantities. This expands the energy options for irradiation and instrument calibration.
