Occupational History
The history of the nuclear weapons complex is also the history of its workers. Rosetta reconstructs occupational activity by connecting worker populations to tasks, locations, materials, processes, monitoring practices, incidents, and the surviving records needed to understand what work actually occurred.
Research pathways
Rosetta separates evidence that a worker or group was present from evidence establishing what tasks were performed, what materials or hazards were encountered, whether monitoring was representative, and what exposure conclusions the surviving record can actually support.
People
Identify production workers, operators, maintenance personnel, construction trades, laboratory staff, instrument technicians, contractors, temporary workers, visitors, and other occupational groups documented at a facility or operation.
Available Now · Continuously DevelopingWork
Connect job titles and worker groups to specific tasks, buildings, rooms, processes, campaigns, maintenance activities, incidents, and periods of operation.
Connect to operations & programs →Hazards
Trace the radioactive materials, chemicals, source forms, equipment, contamination pathways, and work practices relevant to a documented task or worker population.
Connect to materials genealogy →Monitoring
Examine external dosimetry, bioassay, air sampling, contamination surveys, area monitoring, medical surveillance, and other evidence used to characterize occupational conditions.
Available Now · Continuously DevelopingRepresentativeness
Evaluate enrollment criteria, monitoring frequency, sensitivity, coverage of non-routine work, contractor inclusion, changes over time, and evidence of potentially unmonitored populations.
See the evidence-centered method →Events
Connect spills, releases, contamination events, maintenance outages, decontamination, recovery work, unusual entries, and other departures from routine operations to the workers and records involved.
Available Now · Continuously DevelopingEvidence
Follow rosters, payrolls, job classifications, work orders, radiation records, industrial-hygiene records, health-physics reports, training files, incident records, and related archival sources.
Follow the archival record →Compensation context
Connect historical occupational evidence to the separate Rosetta research area addressing EEOICPA, dose reconstruction, Special Exposure Cohort questions, and evidentiary reliability.
Explore EEOICPA / SEC →Non-routine work
Connect event-level worker involvement, monitoring, emergency response, and cleanup to the records that document them.
Explore occurrences & incidents →Occupational evidence standard
A roster can establish that a person or group worked at a site. Additional evidence is needed to establish where they worked, what they did, which materials or hazards were present, how exposure could occur, what monitoring was performed, and whether that monitoring represented the work actually done.
How Rosetta evaluates evidence →Human history
Occupational history links facilities, organizations, materials, operations, shipments, incidents, monitoring systems, and archives. It is where the physical network becomes a human one.
Rosetta presents historical research and source relationships. It does not determine individual medical causation or compensation eligibility.
The private THE ROSETTA WEB™ Master Evidence system remains separate from this website.
