This document specifies the neutron reference radiation fields, in the energy range from thermal up to 20\u00a0MeV, for calibrating neutron-measuring devices used for radiation protection purposes and for determining their response as a function of neutron energy.<\/p>\n

This document is concerned only with the methods of producing and characterizing the neutron reference radiation fields. The procedures for applying these radiation fields for calibrations are described in References [1] and [2].<\/p>\n

The neutron reference radiation fields specified are the following:<\/p>\n

\u2014\u00a0\u00a0\u00a0 neutron fields from radionuclide sources, including neutron fields from sources in a moderator;<\/p>\n

\u2014\u00a0\u00a0\u00a0 neutron fields produced by nuclear reactions with charged particles from accelerators;<\/p>\n

\u2014\u00a0\u00a0\u00a0 neutron fields from reactors.<\/p>\n

In view of the methods of production and use of them, these neutron reference radiation fields are divided, for the purposes of this document, into the following three separate clauses:<\/p>\n

\u2014\u00a0\u00a0\u00a0 In Clause\u00a04, radionuclide neutron sources with wide spectra are specified for the calibration of neutron-measuring devices. These sources should be used by laboratories engaged in the routine calibration of neutron-measuring devices, the particular design of which has already been type tested.<\/p>\n

\u2014\u00a0\u00a0\u00a0 In Clause\u00a05, accelerator-produced monoenergetic neutrons and reactor-produced neutrons with wide or quasi monoenergetic spectra are specified for determining the response of neutron-measuring devices as a function of neutron energy. Since these neutron reference radiation fields are produced at specialized and well-equipped laboratories, only the minimum of experimental detail is given.<\/p>\n

\u2014\u00a0\u00a0\u00a0 In Clause\u00a06, thermal neutron fields are specified. These fields can be produced by moderated radionuclide sources, accelerators, or reactors.<\/p>\n","protected":false},"excerpt":{"rendered":"
