Following the enactment of Part E in 2004, the Department of Labor launched an effort to create the SEM database to assist claimants in substantiating their Part E claims. Part E of EEOICPA covers all occupational illnesses caused by any of the tens of thousands of toxic substances that have been present in the weapons complex. In addition to exposure data, the SEM contains information documenting confirmed causal relationships between certain toxic substances and diagnosed medical conditions. The SEM was created using information from DOE and records of research from recognized medical authorities maintained by the National Library of Medicine. DOL has supplemented the DOE exposure data by conducting an extensive series of round table meetings with former workers across the country to identify materials they worked with, and via other information supplied by claimants and members of the public. DOL continues to expand the database as new information is received. The resulting database has been an invaluable tool for many claimants who had no means of proving, or even knowing, what toxic substances their family member was exposed to.
