The Los Alamos Historical Document Retrieval and Assessment (LAHDRA) Project is assembling pieces of Los Alamos National Laboratory's history to evaluate releases of materials that had the potential to cause off-site health hazards.

The Centers for Disease Control and Prevention (CDC) is conducting this project to systematically review all available documents related to Los Alamos National Laboratory (LANL) operations and identify records that contribute information about releases of chemicals and radionuclides from the site between 1943 and the present. Scientists from ChemRisk, contractor to CDC, are performing the document retrieval and assessment. The project team has access to LANL records that is unprecedented for an independent group studying potential off-site health hazards. Products of the project include:

	summary of historical operations
	listing and ranking of materials released off site
	bibliographic database of relevant documents and interviews
	copies of those documents made available in a local reading room

After this project is completed, CDC will work with LANL stakeholders to determine whether the information warrants a detailed investigation of potential public exposures from any LANL operations.
