There are many synchrotron radiation facilities in use around the world, and several more are under construction. Most of the synchrotron radiation facilities consist of an injector, a storage ring, and many synchrotron radiation beam lines. Some of the design and operational features for radiation safety of storage rings and beam lines are different from other types of high-energy accelerators. Radiation safety design and operational practices among five third-generation synchrotron radiation facilities (ALS, APS, NSLS, SPring8 and SSRL) are presented. Issues such as beam loss scenarios and shielding design for storage rings and beam lines, radiation monitoring systems, as well as operational issues for these facilities have been compared. This collaborative work provides a sound basis for the radiation safety consideration that should be addressed in the design and operation of synchrotron light sources. *This work is supported by Department of Energy contract DE-AC03-76SF00515.
