Abstract

The recent increasing use of γ-ray industrial computed tomography (γ-ray ICT) in various fields has induced greater attention to its performance as well as to considerations of radiation safety. It is understood that radiation protection planning cannot be sacrificed for the sake of CT image quality during the design, manufacture, and layout of γ-ray ICT systems. In the present work, we describe a typical γ-ray ICT system in brief, and, based on experience and pertinent examples, we propose design requirements for ensuring the radiation safety of the sealed radioactive source, source container, and workspace. The design examples and dose rate measurement results illustrate that the proposed design standards are reasonable, feasible, and safe, and are therefore meaningful for the design, manufacture, and layout of γ-ray ICT systems. This paper discussed the predominant measures associated with the radiation protection of γ-ray ICT systems in accordance with the pertinent Chinese standards. In addition, based on experience and pertinent examples, the design requirements for ensuring the radiation safety of a sealed radioactive source, source container, and workspace were defined in detail. The design examples and dose rate measurements conducted in conjunction with a γ-ray ICT system and workspace employing the proposed design standards have illustrated that the proposals provided in this paper are reasonable, feasible, and safe, and are therefore meaningful for the design, manufacture, and layout of γ-ray ICT systems.
