Abstract

This U.S. Nuclear Regulatory Commission (NRC) report documents the circumstances surrounding the September 13, 1983, cesium-137 sealed source rupture incident at the Shelwell Services, Inc., facility in Hebron, Ohio. It focuses on the period from approximately 4:00 p.m. (EDT) on September 13, 1983, when the source ruptured, to October 5, 1983, when the radiological emergency response aspects of the event were concluded. Information outside these periods is recounted as necessary. The incident resulted in radiation doses to two licensee employees that exceeded the regulatory limits for whole-body and extremity exposures, and contamination of the licensee's facility, private residences, public buildings, and the personal effects of the licensee's employees, families, and friends. The emergency response required the combined efforts of NRC, U. S. Department of Energy, and state personnel. The report describes the factual information and significant findings associated with the event and, thereby, provides a data base for subsequent detailed analyses and recommendations by various NRC offices.
