At approximately 1115 EDT on 10/25/11 an intern entered the dry gamma room at the Rhode Island Nuclear Science Center Facility during an ion probe calibration procedure. The intern received an estimated unplanned dose of between 2-3 rem based on a stay time of 5 minutes in a 500 mr/min field. His dosimetry, an OSL (Optically Stimulated Luminescence) badge, has been sent to Landauer for expedited processing. The dry gamma room is properly posted as a high radiation area with administrative controls in effect to limit access. The assistant Director of the facility is performing an investigation including event reconstruction to determine the cause.
