Materials, Isotopes & Components
Materials connect places that can otherwise look unrelated. Uranium, plutonium, tritium, fission products, sealed sources, specialty compounds, weapons components, and isotopic power systems moved through laboratories, production plants, contractors, test sites, and storage facilities—leaving documentary trails in procurement, accountability, shipping, monitoring, and operational records.
Public dataset
Trace documented historical components through design authority, facility, process, material, parent assembly, program, and surviving evidence—without filling unresolved links by inference.
Research pathways
This gateway is being released as an evidence-first directory. A material appearing at a facility does not by itself establish a particular worker exposure, shipment, process, or dose. Those relationships become public only when the supporting source record is ready.
Radionuclides
Follow uranium, plutonium, tritium, thorium, fission products, activation products, and other radionuclides through documented facilities, programs, and records.
Available Now · Continuously DevelopingPhysical form
Distinguish metal, oxide, salt, gas, solution, powder, sealed source, tritide, fuel, and other forms whose physical and chemical properties matter to historical reconstruction.
Available Now · Continuously DevelopingHardware
Connect components, subassemblies, source packages, reservoirs, thermopiles, generators, instrumentation, and other hardware to the places and records that document them.
Available Now · Continuously DevelopingPower
Trace radioisotope heat sources, thermoelectric systems, RTG components, assembly work, transfers, maintenance, and decontamination through surviving evidence.
Available Now · Continuously DevelopingSpecialty matter
Recover specialty gases, glass, ceramics, metals, electronic materials, standards, and instrument-related substances that supported research and weapons production.
Available Now · Continuously DevelopingTransformation
Connect machining, casting, chemical processing, glassing, coating, sampling, decontamination, recovery, fabrication, and other processes to material form and workplace evidence.
Available Now · Continuously DevelopingMovement
Follow documented movement between facilities and organizations through shipping papers, receiving records, accountability forms, procurement files, inventories, and disposition records.
Follow the records →Recovery
Preserve code names, ambiguous isotope references, undocumented source forms, missing serials, and other material questions without promoting them to established fact.
See archival research →Core Rosetta framework
Trace nuclear material from origin to disposition—and preserve every documentary link, transformation, transfer, and gap along the way.
Canonical genealogy
Nuclear materials rarely remained in one place or one form. Rosetta reconstructs their documentary genealogy across production, processing, transformation, incorporation into components, transfer, operational use, recovery, and disposition. The purpose is not simply to identify where a material appeared, but to recover the evidence connecting its successive forms, places, uses, worker populations, and surviving records.
A missing link remains a missing link. Rosetta does not convert chronology, proximity, or technical plausibility into a documented relationship. Each connection retains its own evidentiary status, including documented evidence, indirect evidence, research leads, unresolved questions, and missing-record targets.
Start with matter
Follow uranium, plutonium, thorium, tritium, promethium, fission products, activation products, and other materials across their documented histories.
Available Now · Continuously DevelopingTrack change
Distinguish metal, oxide, salt, solution, gas, powder, sealed source, fuel, tritide, scrap, recovered material, and other changing forms.
Available Now · Continuously DevelopingFollow movement
Connect sender, material, form, quantity, date, recipient, facility, operation, and disposition only where the documentary trail supports the relationship.
Available Now · Continuously DevelopingReturn to evidence
Reconstruct genealogy through accountability forms, bills of lading, procurement and receiving files, production records, inventories, surveys, monitoring records, and disposition documentation.
Explore archival evidence →Evidence standard
Rosetta separates evidence that a material existed at a place from evidence establishing its form, quantity, process, movement, worker contact, monitoring conditions, or exposure significance. Public connections must remain faithful to what the surviving record actually supports.
How Rosetta evaluates evidence →Public release
Individual isotope and component pathways will become active as source records are verified and prepared for public presentation. Unresolved relationships remain visibly unresolved.
The private THE ROSETTA WEB™ Master Evidence system remains separate from this website.
