GB/T 17947-2008Activity measurements of solid materials considered for recycling re-use, or disposal as non-radioactive waste (English PDF)

Foreword

This standard is identical with ISO 11932:1996 Radioactive "for recycling, reuse or disposal of radioactive waste for non-solid materials Activity measurement. " this standard made the following editorial changes.

--- Remove the foreword and introduction of international standards;

--- Deletion of some of the terms and definitions (for example. activity, specific activity, surface contamination and surface activity in GB/T 4960.5-1996 "nuclear Scientific and technical terminology radiation protection and security "in the existing provisions).

This standard replaces GB/T 17947-2000 "for recycling, reuse or for solids non-radioactive waste disposal radioactive live Measurement. " This standard compared with GB/T 17947-2000, the main changes are.

--- Deletion of the ISO "Preface" and "Introduction";

--- A reference standard complements update.

This standard Annex A, Annex B normative appendix.

The standard proposed by China National Nuclear Corporation.

This standard by the National Standardization Technical Committee of nuclear energy.

This standard was drafted. Nuclear Industry Standardization Institute, China Institute for Radiation Protection.

1 Scope

This standard specifies the operation and decommissioning of nuclear facilities, to be recycled, reused or as a solid material non-discharge of radioactive waste disposal Principles and methods of measuring radioactive activity.

This standard applies to the operation and decommissioning of nuclear facilities, to be recycled, reused or as a solid material non-discharge of radioactive waste disposal Radioactive activity measurement, in order to determine whether these substances meet the clearance criteria published.

Other sources, to be recycled, reused or for radioactivity measurement of solid material non-radioactive waste disposal, can refer to this standard Associate Executive.

This standard does not apply to a general sense of radioactive waste.
