Complications of unintentional dural puncture during labour epidural analgesia: a 10-year retrospective observational study.

Introduction: Unintentional dural puncture (UDP) occurs in 0.5-1.5% of labour epidural analgesia cases.

Health physics challenges involved with opening a "seventeen-inch" concrete waste vault.

This paper describes the various activities involved with opening a sealed legacy "Seventeen-inch" concrete vault and the health physics challenges and solutions employed. As part of a legacy waste stream that was removed from the former Hazardous Waste Management Facility at Brookhaven National Laboratory, the "Seventeen-inch" concrete vault labeled 1-95 was moved to the new Waste Management Facility for ultimate disposal. Because the vault contained 239Pu foils with a total activity in excess of the transuranic waste limits, the foils needed to be removed and repackaged for disposal.
