Title	Agreement State Report - Potential Dose to Embryo or Fetus
Event Description	The State of Colorado provided the following information via email: In accordance with [Colorado Code] 7.23.1 [similar to 10 CFR 35.3047], Mercy Medical Center, Durango, CO is reporting a dose to an embryo/fetus in excess of 5 mSv. On March 16, 2010 1110 MBq (30 mCi) of I-131 was administered to a 31 [year old] female patient. A serum blood [pregnancy] test was taken prior to administration and was negative. On April 26, 2010 the patient, thinking she might be pregnant, took a home urine [pregnancy] test that showed positive. Pregnancy was confirmed by blood serum test on April 27, 2010. Patients OB/GYN physician estimates conception occurred on March 13, 2010. Fetal dose was estimated to be approximately 80 mGy (8 rem). At this dose level and administration time in relation to fetal development (still in blastogenesis), there will likely be no impact upon subsequent fetal development or subsequent health risks. The patient has been notified as such. The Department has begun an investigation of this incident and will keep the NRC informed of the status of our investigation. The licensee stated that all procedures to prevent this occurrence were followed. Human chorionic gonadotropin (Hcg) is not detectable in the blood until 7 - 12 days post conception. The licensee is considering including additional questions during the screening process.
