Indus-I and Indus-2 are two Synchrotron Radiation Sources (SRS) operational at RRCAT, Indore. During shut down of these accelerators for maintenance purpose, residual radioactivity measurements were carried out. The present paper describes the measurements carried out and the radio-isotopes identified. Maximum dose rate due to induced activity obtained is 28 μSv/h near dipole-5 of booster synchrotron after 12 h of cooling time. In case of Indus-I and Indus-2 SRS, the dose rate due to induced radioactivity is found to be of the order of 2-3 μSv/h. The radio isotopes identified at these beam loss locations are beta emitters that do not pose serious external hazard to the working personnel.
