NATIONAL FOREWORD

This Indian Standard which is identical with ISO 12749-1 : 2020 ‘Nuclear energy - Vocabulary - Part 1: General terminology’ 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.

Unambiguous communication of nuclear energy and radiological concepts is crucial taking into account the relevant implications that may arise from misunderstandings with regard to equipment and materials involved in the standards dealing with these activities. In order to harmonizing the terminology regarding nuclear and radiological activities, this part of Indian Standard will contribute to provide general, crosscutting terms and definitions to meet users’ requirements. It will also improve promotion, knowledge and use of national standards dealing with nuclear energy, nuclear technologies and radiological protection and will help experts developing technical standards to avoid overlapping and contradiction.
