ISO International Standard 8529, "Neutron reference radiation fields" provides basic guidance on neutron metrology for both primary and secondary calibration laboratories. Its three parts, namely Part 1: "Characteristics and methods of production" [1], Part 2: "Calibration fundamentals of radiation protection devices related to the basic quantities characterizing the radiation field" [2] and Part 3: "Calibration of area and personal dosimeters and determination of response as a function of energy and angle of incidence" [3], are under revision by ISO/TC 85 / SC 2 (Radiological Protection) / WG 2 (Reference Radiation Fields) / SG3 (Neutrons). The revised Part 1 was published in November 2021 as a Second Edition [4]. The changes introduced in the new version of the standard will be discussed. Revised spectra, which take into account new data, and which have implications for fluence to dose equivalent conversion coefficients, are the main changes.
