This study presents the risks associated with high dose I treatment which is used in nuclear medicine Patients were confined to two isolation rooms which were completely covered with lead Each room is designed for two beds which are separated by lead separators In the fixed activity protocol a high activity GBq mCi I was administered to patients In general the patients were isolated for a period of days The dose rates were measured at m from the patient rsquo s thyroid and abdominal levels at different time intervals The clean and unclean room dose rate measurements were performed at each isolated room These were mRh and mRh respectively The maximum dose rate was measured at the toilet bowl Moreover the pillow had mRh at the unclean room The dose measurements at surrounding rooms and service door corridor were done with patients allocated in their room There were micro Rh and micro Rh respectively The measurements at the same places without patients were micro Rh and micro Rh respectively The time dependent dose curves for each therapeutic value of and GBq were generated by exponential fitting curves for each patient Average and standard deviation of cumulated dose mR at m about level of abdominal and thyroid were calculated along hospitalization period maximum h
