Scope

Scope: This document specifies the designation, specifications, structure, technical requirements, inspection methods, inspection rules, marking, data, storage, packaging, and transportation of cobalt-60γ radiation sources used in stereotactic radiotherapy systems. This document is applicable to cobalt-60γ radiation sources used in stereotactic radiotherapy systems. Main technical content: (1) Technical requirements: Requirements for the source core material. (2) Technical requirements: It is recommended to use 022Cr17Ni12Mo2 for the shell material. (3) Technical requirements: Requirements for the spacer block, welding requirements for the shell, and uncertainty of output activity rate and loading activity rate. (4) Technical requirements: The tolerance of coaxiality between the inner hole and the outer shape of the shell shall not exceed 0.05mm. (5) Technical requirements: The outer diameter and length of the source shall not exceed the maximum allowable values of its equipment. (6) Technical requirements: The safety performance level shall not be lower than GB4075-2009/C63535 or E63535. (7) Technical requirements: Limits of leakage and surface radioactive contamination: <200Bq. (8) Technical requirements: Requirements for output consistency: ±10%
