Event chronology
Occurrence & Incident Register
Organize documented abnormal events by date, facility, building or area, operation, event type, source record, and evidentiary status.
Available Now · Continuously DevelopingOccurrences, Incidents & Accidents
Reconstruct what happened when routine operations broke down.
Rosetta preserves documented abnormal events—from spills, fires, leaks, contamination episodes, criticality concerns, equipment failures, and releases to emergency responses, unusual maintenance, and other non-routine conditions—and reconnects them to places, materials, workers, monitoring, corrective actions, and the records that survive.
EVENT → DATE → FACILITY → LOCATION → OPERATION → MATERIAL → WORKERS → MONITORING → CORRECTIVE ACTION → RECORD
Research pathways
Build an event from the record outward.
This foundation establishes the public home for event-level evidence. Individual events will be published only when their dates, locations, source records, and evidentiary status can be stated responsibly.
△
Event type
Fires, Explosions & Equipment Failures
Trace fires, explosions, ruptures, loss-of-containment events, failed systems, damaged sources, and related operational disruptions without assuming an exposure outcome.
Explore operations →◌
Radiological event
Leaks, Releases & Contamination
Connect releases, spills, airborne activity, contamination discoveries, migration, and cleanup records to the material involved and the monitoring evidence that documents the event.
Explore materials →⚠
Non-routine work
Emergency Response & Recovery
Identify responders, maintenance crews, decontamination teams, operators, contractors, and other groups involved in stabilization, investigation, repair, recovery, or cleanup where the records support that linkage.
Explore occupational history →⌁
Measurement
Event Monitoring & Dosimetry
Track area monitors, air samples, contamination surveys, personal dosimetry, bioassay, special sampling, instrument anomalies, and other measurements made before, during, or after an event.
Explore monitoring evidence →▤
Documentation
Occurrence Reports & Investigations
Recover logs, unusual occurrence reports, investigation memoranda, health-physics reports, corrective-action records, photographs, drawings, and later summaries that preserve the event history.
Explore documentary records →↺
Aftermath
Corrective Actions & Lessons Learned
Preserve documented changes to procedures, equipment, containment, monitoring, training, staffing, or work controls that followed an event.

Recovery
Missing Event Records
Track referenced but unrecovered logs, attachments, investigation files, worker lists, monitoring results, photographs, and expected occurrence-report series as explicit research targets.
Explore missing evidence →Event evidence standard
An incident is not automatically an exposure.
Rosetta distinguishes evidence that an event occurred from evidence identifying the material involved, the workers present, the pathway of potential exposure, the monitoring performed, and any resulting dose or intake. Those are separate historical propositions and must be supported separately.
How Rosetta evaluates evidence →Foundation edition
Event architecture now. Event records next.
This page establishes the public structure for an eventual cross-complex occurrence and accident database. Verified event records can be added incrementally as source documentation is recovered and reviewed.
The private THE ROSETTA WEB™ Master Evidence system remains separate from this public website.
Future public event register
What a published event record should preserve.
Rosetta Event ID · event date · facility · building/area · operation · event type · material/radionuclide · release or contamination pathway · worker groups · monitoring performed · documented consequences · corrective action · source record · repository · page citation · evidentiary status · related Rosetta records
Where a field is unknown, Rosetta will preserve it as unknown rather than reconstructing it from plausibility alone.
“The event record matters most when it preserves the difference between what happened, what was measured, who was involved, and what remains unknown.”
