The Environmental Agent Service (EAS) Registries is the information system encompassing the Ionizing Radiation Registry (IRR), the Agent Orange Registry (AOR), and the Gulf War Registry (GWR) which also includes related Depleted Uranium (DU) exams. These registries were originally developed using paper code sheets that were sent to the VA Austin Information Technology Center where typists converted to data files on the mainframe. The Registries have undergone a modernization and simplification effort that allows the entry of data via a web interface at https://vaww.registries.aac.va.gov/eas/ by staff at the VA medical centers. In compliance with the Federal Information Systems Management Act (FISMA) this is considered a single system of records with the three registry components i.e. IRR, AOR, GWR with DU that have been integrated into a single Oracle database. Please see individual Monograph entries for specific details on: Ionizing Radiation Registry (IRR), Agent Orange Registry (AOR), and the Gulf War Registry (GWR).

The Post-Deployment Health Strategic Healthcare Group (PDHSHG) Registry System of Records is the information system encompassing the Ionizing Radiation Registry (IRR), the Agent Orange Registry (AOR), and the Gulf War Registry (GWR) which also includes related Depleted Uranium (DU) exams. The AOR area of the PDH database contains VA entered information about U.S. Veterans who served in the Republic of Vietnam between 1962 and 1975, in Korea between April 1968 and August 1971, or who had a registry exam because of possible exposure to dioxin or another toxic substance in an herbicide during the conduct of, or as a result of, the testing, transporting, or spraying of herbicides for military purposes.
