POSSIBLE OVEREXPOSURE BASED ON DOSIMETRY READING
On 2/1/2002, the University Radiation Safety Officer received the 10/15-11/14/2001 TLD results from their dosimetry processor (Landauer), which indicated that an individual had received an extremity dose of 72.6 rem to the hand. This result was based on readings from a ring dosimeter. However, based upon results from another ring dosimeter worn by the individual during the period (114 mrem) , the individual's whole body dosimetery (33 mrem), and the individual's work duties, the RSO believes that this result may be in error. The RSO has been in contact with NRC Region III regarding this incident.
