Foreword

This standard corresponds to ISO /ASTM51275.2004 "the use of radiation color film dosimetry system standards" (in English) and ISO / ASTM51276.2002 "using polymethylmethacrylate dosimetry system standards" (in English), and ISO /ASTM51275.2004 And ISO /ASTM51276.2002 non-equivalent. The technical differences between the standards with international standards as follows. a) The ISO /ASTM51275 and ISO /ASTM51276 merge the contents of two international standards for our country standard; b) In the ISO /ASTM51276.2002 standard Information Appendix A of the original content, based on the increase of the radiation dosimeter color film Relevant content (see Appendix A). For ease of use, this standard also made the following editorial changes. c) according to the Chinese custom for some formatting has been modified. d) In the second chapter, "normative references", the referenced ISO and ASTM standards, who have converted to our standards (including meter The amount of test regulations), the reference to our standards. This standard replaces GB/T 15053-1994 "use of radiation color film and polymethyl methacrylate absorbed dose measurement system Standard Method "dose. Compared with the standard GB/T 15053-1994 The main changes are as follows. --- Redefined the dosimeters used for radiant energy and the irradiation temperature range (see 1994 edition of 1.2.1,1.2.2; Excerpts 1.2.1,1.2.2); --- Added "Normative references" (see Chapter 2 of this edition); --- In the "Terms and definitions" clause added some terminology, and some of the terms of the original redefined (see 1994 edition Excerpts of chapter 3); Chapter 2; --- The title of "equipment" chapter to "dose measurement system" (see the 1994 version of Chapter 4; Chapter 5 of this edition); --- Added "equipment performance check" the technical content (see Chapter 6 of this edition, 6.1, 6.2); --- On the "Calibration of dosimetry systems" chapters made big adjustment, and added, "is calibrated dosimeter share volume in the radiation field Changes in dose rate should be less than ± 1% (range ≤2%) "requirements (see the 1994 version of Chapter 5; Chapter 7 of this edition); --- Added "Batch dosimeters characterization" of the technical content (see Chapter 9 edition); --- Increased "dose measurement system application" of technical content (see edition Chapter 10); --- Use the "Measurement Uncertainty" in chapter headings and related technical content replaces the 1994 version of the "Error Analysis" technical content (see 1994 version of Chapter 8; first edition Chapter 12); Appendix A of this standard is an informative annex. The standard proposed by China National Nuclear Corporation. This standard by the National Standardization Technical Committee of nuclear energy. This standard was drafted. China Institute of Metrology. The main drafters. Zhang Yanli, summer shading, Gong Xiaoming. This standard replaces the standards previously issued as follows. --- GB/T 15053-1994.

1 Scope

1.1 standard specifies the use of radiation color film and polymethyl methacrylate (PMMA) dosimetry systems for measuring absorbed dose of exercise For and measurement procedures. This standard applies to both dosimetry systems measure the photon or electron irradiation dose absorbed water is expressed according to the material The absorbed dose. Both dose measurement system is as working-level dose measuring system (see GB/T 16640). 1.2 This standard specifies two doses of the measurement system applicable conditions are as follows. 1.2.1 radiation color film dosimetry system a) absorbed dose range. 1Gy ~ 100kGy. b) absorbed dose rate range. 1 × 10-2Gy · s-1 ~ 1 × 1013Gy · s-1. c) radiation energy range. 0.1MeV ~ 50MeV (photons and electrons). d) irradiation temperature range. -78 ℃ ~ 60 ℃. 1.2.2 polymethyl methacrylate (PMMA) dosimetry systems a) absorbed dose range. 0.1Gy ~ 100kGy. b) absorbed dose rate range. 1 × 10-2Gy · s-1 ~ 1 × 107Gy · s-1. c) radiation energy range. 0.1MeV ~ 50MeV (photon); 3MeV ~ 50MeV (electrons). d) irradiation temperature range. -78 ℃ ~ 50 ℃. 1.3 This standard does not involve safety problems associated with its use (if it exists). Users of this standard is responsible for establishing the applicable safety and health Standards, and prior to use to determine the applicable limits.
