808-810There are 26
synchrotron radiation beamlines planned to be installed in Indus-2 for various
applications. 5 are commissioned, 2 are under commissioning trial stage and
several are under installation. During operation of these beamlines, radiation
levels are monitored within and outside hutches. During initial trial runs
streaming of radiation to accessible areas through gaps in the hutch structure
and overlaps was observed. Shield augmentation and reducing gap between
overlaps are found to be effective in preventing streaming of radiation. The
paper describes radiation safety features, surveillance program and radiation levels
in and around synchrotron radiation beamlines hutches of Indus-2
