Title	Agreement State Report Involving Personnel Radiation Exposure
Event Description	On 01/12/04, the State of California received a report from Schlumberger Technology of an incident that occurred about 1800 PST on 01/10/04. A 1.3 curie Cs-137 source fell off of its tool. A rig hand picked up the source with his fingertips thinking it was the base of a lightbulb. A Schlumberger crew member told the worker to leave it on the deck. The source was recovered with the source handling tool, and returned it to the shielded container. Touching exposure was estimated to be 20 mrem with calculations based on maximum touching time of 10 seconds. Whole body exposure was estimated to be 2.9 mrem with calculation exposure based on beginning at 6 feet from the source and closest distance at 2.5 feet for maximum of 2 minutes. The source has exposure characteristics of 2 mrem/hr at 200 inches (min) from shielded (dovetail) end, and 2 mrem/hr at 680 inches (max) from the non-shielded end.
