2013 General Activities on Department of Energy (DOE) Cases

DCAS will reconstruct radiation doses by evaluating all appropriate data relevant to which an individual worker or group of workers have been exposed, particularly when radiation monitoring data are unavailable, incomplete, or of poor quality. The data used for the dose reconstructions will be obtained through requests sent to DOE and data search and capture efforts.

DCAS along with Oak Ridge Associated Universities (ORAU), the contractor hired to support NIOSH's responsibilities under the Act, have been involved in data search and capture efforts. These efforts are being conducted at various DOE sites and federal and private records storage locations throughout the United States to retrieve radiation monitoring data needed to conduct dose reconstructions.
