New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 1) which is identical with ISO 8529-1 : 2021 ‘Neutron Reference Radiations Fields - Part 1 Characteristics and Methods of Production’ issued by the International Organization for Standardization (ISO), was adopted by the Bureau of Indian Standards on the recommendation of the Nuclear Energy for Peaceful Applications Sectional Committee and approval of the Chemical Division Council.

This part specifies the neutron reference radiation fields, in the energy range from thermal up to 20 MeV, for calibrating neutron-measuring devices used for radiation protection purposes and for determining their response as a function of neutron energy. The neutron reference radiation fields specified are the following:

a) neutron fields from radionuclide sources, including neutron fields from sources in a moderator;

b) neutron fields produced by nuclear reactions with charged particles from accelerators;

c) neutron fields from reactors.
