High intensity and predominantly low energy Synchrotron Radiation (SR) are produced at INDUS-II Synchrotron Radiation Source at Raja Ramanna Centre for Advanced Technology (RRCAT). SR monitoring instruments were developed to measure and monitor SR radiations. Salient features of these monitors include high sensitivity, isotropic response, audio alarm indicating radiation levels above I mRIh and outputs for controlling the door interlocks. Paper describes the design criteria and results of measurements.
