The current research paper uses a whole-body counter to assess internal contamination for individuals working in nuclear medicine and research laboratories. High purity germanium detector Whole Body Counter with a relative efficiency of 25%; aluminum endcap with 1.5 mm was calibrated using a mixed gamma source. It consists of three parts; high purity germanium detector gamma ray spectrometer, shielding room, and Phantom. Gamma internal monitoring was performed on eight volunteers inhaled with 131 I and two individuals contaminated with 99m Tc in organ geometry. Results: The committed effective dose for individuals was lower than dose constrain and within the dose limit according to ICRP recommendations. Conclusions: The study indicates that the HpGe whole body counter has the capability to detect organ contamination such as 131 I in thyroid gland, 99m Tc in whole body geometry.
