GB/T 25306-2010Standard of electron accelerator facility engineering for radiation processing (English PDF)

GB/T 25306-2010 is the English-translated version of 辐射加工用电子加速器工程通用规范.

GB/T 25306-2010 specifies the composition and the technical requirements of a radiation processing electron accelerator project: the classification and model naming of the electron accelerator means and of the under beam means, the content, requirements, design, construction and quality supervision of the plant, the installation and testing, and the acceptance.

Clause 1 applies it to radiation processing electron accelerator projects of every type in the energy range 0.15 MeV to 15 MeV.

The table of contents runs from the scope and the normative references through the terms and definitions, the composition of the project, the electron accelerator means, the under beam means, the control system and the plant to installation and testing and finally acceptance, and closes with Appendix A on methods of measurement and formulae, which the foreword declares normative, and three informative annexes: Annex B on individual dose limits and the effective dose for different tissues or organs, Annex C on occupational exposure limits for microwaves, high frequency electromagnetic fields and harmful gases, and Annex D on the measurement of beam focal spot diameter, scanning frequency and pulse repetition rate.

Clause 3 defines five terms: radiation processing, the process of acting on materials with ionizing radiation to obtain the intended quality or performance; radiation facility, made up of the radiation chamber, the electron accelerator system, the under beam apparatus, the control and radiation processing equipment systems, the safety facilities and other parts; the radiation processing electron accelerator apparatus, the means for generating and accelerating the electron beam and extracting it for radiation processing; the under beam apparatus, the means outside the beam extraction window that transports the materials for radiation processing; and the reference plane, the plane selected perpendicular to the beam axis in the radiation field.

The draft on the page stops at the end of clause 3, so the project composition, plant, installation and acceptance clauses themselves are not shown; the page estimates the full text at about 28,280 words.

Clause 2 cites GB 3095, GB 5172-1985, GB 5749, GB/T 15447, GB/T 16841, GB 18871-2002, GBZ 1-2002, GBZ 2.1-2007, GBZ 2.2-2007 and JJG 772.

It was proposed by China National Nuclear Corporation, is handled by the National Standardization Technical Committee of nuclear energy and was drafted mainly by the Shanghai Institute of Applied Physics of the Chinese Academy of Sciences, the Beijing Institute of Machinery Industry Automation and the Institute of Nuclear Industry Standardization, among others the page names. It was issued on 2010-11-10 and has applied since 2011-05-01.
