Ohio Department of Health (ODH), Bureau of Radiation Protection (BPR) was notified of a possible overexposures to a member of the general public which occurred on 4/20/10 at the Ohio State University located in Columbus, Ohio. A patient received a temporary implant of Cs-137 and Ir-192 seeds on April 16-18, 2010. The patient's visitor (her fianc�) was instructed by the licensee that he could stay no longer than 2 hours with the patient in a twenty four hour period, and must stay behind the bedside shield during these visitations. On Tuesday, April 20, 2010, the licensee was informed by the Assistant Nurse Manager that the fianc� spent the night in the patient's room on two consecutive nights. In addition, the initial investigation by the licensee indicates that the visitor told the Assistant Nurse Manager that he slept in the same bed with the patient both nights. Nursing Management personnel are in the process of interviewing staff members that were involved directly with the care of the implant patient to verify that the fianc� was in the room overnight with the patient. A preliminary and conservative worst case dose estimate for the visitor is 6 Rad (6 cGy) whole body exposure, based on a 16-hour stay time (8 hours each night for two nights). ODH BRP will continue to collect information of this event and conduct an investigation. The licensee has initiated an internal investigation. Ohio Report OH100005
