Foreword

GB/T 14057 "decontamination of radioactively contaminated surfaces" is divided into two parts. Test and evaluation of the ease of decontamination methods;. --- Part 1 --- Part 2. Test methods for textile detergents. This section GB/T Part of 214,057. This section uses redrafted law revision using ISO 9271.1992 test decontamination textile detergents "radioactively contaminated surfaces method". This part of ISO 9271.1992 technical differences and their reasons are as follows. --- To comply with the relevant requirements of the national standard, international standard delete ISO 9271.1992 in nine normative references, increase GB/T 8629 reference; --- For ease of reference, the terms and definitions 3.4,3.5,3.6,3.7,3.8 increased representation symbols, which increased 3.7,3.8 formula; --- Chapter 5, 5.4, 5.5 adds two instruments equipment; --- Since the original text 7.1.2 "Save" content conditions are ripe, especially the "Save" Content singled out becomes 7.1.4; --- The original contents of Chapter 10 into Chapter 4; --- To make the content more complete smooth, increasing the Appendix D, Appendix E, according to the order they appear in the original text, adjust the appendix number The changes to Appendix C Appendix E, Appendix C. Appendix E becomes This Part replaces GB/T 15850-1995 "Standard Test Method for decontamination of radioactive contamination of the surface of the textile detergent." Section compared with the GB/T 15850-1995 The main changes are as follows. --- Under the current standard writing rules for the preparation of the national format has been modified; --- Representation of individual provisions were revised and improved; --- For ease of use, the GB/T 15850-1995 and GB/T 14057-1993 integration as part of a standard two. This section of the Appendix A, Appendix B, Appendix C, Appendix E is normative appendix, Appendix D is an informative annex. This part is proposed by the China National Nuclear Corporation. This part of the National Nuclear Energy Standardization Technical Committee (SAC/TC58) centralized. Drafting this Part. Nuclear Industry Standardization Institute, China Institute for Radiation Protection. The main drafters of this section. Renxian Wen, Liu warehouse. This part of the standard replaces the previous editions as. GB/T 15850-1995. Decontamination of radioactively contaminated surfaces Part 2. Test methods for textile detergents

1 Scope

This section defines the test method for testing textile detergent decontamination efficiency. This section applies to tests under laboratory conditions and evaluation of detergent solution for decontamination of radioactive contamination textile effect. This section does not apply to test, evaluate the capacity of non-radioactive clear detergent dirt, does not apply to the actual evaluation textile detergent should With decontamination effect.

3 Terms and Definitions

The following terms and definitions apply to this section. 3.1 Pollution contamination Test contaminated with radioactive substances on textiles. 3.2 Pollution specimen contaminatedtextilespecimen In the manner prescribed pollution decontamination detergents used to determine the efficiency of the textile reference specimens. 3.3 Decontamination decontamination The removal of all or part of the radioactive contamination. 3.4 Than the count rate specificpulserate SCR With optional radiation measuring instruments, at a given geometry measured per milliliter of solution contamination measuring instrument count rate. When measuring 50μL pollution solution was dropped on a textile specimen, measured after drying count and calculate the ratio of the count rate of contamination of the solution, (min · mL) -1. 3.5 The residue count rate residualpulserate RCR Meter with a choice of radiation measuring instruments, at a given geometry, measured after decontamination on contaminated specimens remaining radionuclides
