Health hazard evaluation report: HETA-96-0198-2651, Portsmouth Gaseous Diffusion Plant, Piketon, Ohio.
Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control and Prevention, National Institute for Occupational Safety and Health, HETA 96-0198-2651, 1997 Sep; :1-36
The National Institute for Occupational Safety and Health (NIOSH) received a request for a Health Hazard Evaluation (HHE) to evaluate worker exposures to neutron radiation at the Portsmouth gaseous diffusion plant (PORTS) operated by the Lockheed Martin Utility Services, Inc. (LMUS) in Piketon, Ohio. The request was submitted by two separate union safety representatives and described the hazard as a chronic exposure to neutron radiation during various production, maintenance and security activities. It also stated that neutron doses have not been recorded in the workers' dose histories for the past 40 years. In response to this request, NIOSH conducted two site visits between November 1996 and February 1997 to: determine if potential neutron exposures exist at the site; identify neutron sources; identify work areas or job titles having the greatest potential for neutron exposures; quantify neutron doses by work area or job title; determine past reporting and recording practices regarding neutron doses; and assess the feasibility of reconstructing past neutron doses.
