Introducing
Radioactive Inventory Management System
We built for the regulations you answer to
From the moment a radioactive package arrives to the day waste clears — every isotope, every record, every compliance obligation unified in one purpose-built platform.
The name
/muh·REE·chee/ · Sanskrit मरीचि — “a ray of light,” “a mote of light”
In the Vedic tradition, Marichi is the first of the seven great sages — born of light, the one who brings illumination to what cannot otherwise be seen. The name carries a second, fitting meaning: a particle of light.
Radioactive material is, by nature, invisible. Activity decays silently. Records scatter across binders, spreadsheets, and people’s memory. Risk hides in the gaps.
Marichi exists to make the invisible visible — turning radiation, inventory, and compliance into a single, clear, trustworthy view of your site.
Real-time activity, decay status, and license headroom — always visible, never guessed.
The logo's atom and glowing nucleus reflect the science Marichi was built to manage.
Every view is backed by an immutable, audit-ready record an inspector can trust.
What it does
Fourteen connected modules replace the binders, spreadsheets, and standalone tools your radiation safety program runs on today — with decay math, alerts, and audit trails built in.
A real-time home screen showing total activity against your license limit, waste-clearance forecasting, and an RSO approval gate for overages.
License headroom
Multi-site view
Overage gate
Calendar
A site wide isotope database with live decay tracking. Calculating current activity for every source automatically.
Isotope Database
Calibration Sources
Decay Tools & Schematics
Log incoming packages contemporaneously. Monitor TI and contamination, capture documentation, and track shipments in and out of your facility.
RAM Tracking
Wipe / survey readings
Document capture
Classify waste into activity-tiered bins, auto-calculate the clear date, and export audit-ready Excel trails on a schedule.
Bin classification
Time-to-safe calc
Audit exports
Track every meter and scanner with calibration due-dates. Automatic color-coded alerts to notify users of upcoming dates, and one-click disable for out-of-cal devices.
Instrument List
Call alerts
CoA archive
Track radiation dose per worker across electronic dosimeters and third-party TLD badge services, with period and year-to-date reporting.
Dose by person
TLD integration
YTD reports
Quick one click disable
Structured incident reporting with severity classification, automated notifications, and a complete chain of custody complete with built-in escalation protocol.
Incident Reporting
Auto-notify
Audit trail
A HIPAA/FDA-compliant archive for SOPs, licenses, SDS, training, and regulatory filings — versioned and access-controlled.
SOPs & manuals
SDS
WORM retention
Role-based access for every user, full activity history, and hooks into your QMS, ERP, and dosimetry provider portals.
RBAC
QMS / ERP hooks
Multi-site
Scannable, decision-first, and fast — the dashboard surfaces what’s overdue, what’s over limit, and what clears soon, the moment you sign in.
Who it's for
Marichi adapts to the workflows and regulators of every setting that handles radioactive material.
PET/SPECT, theranostics, and brachytherapy programs managing short-lived isotopes and patient-dose records.
University EH&S and core labs tracking many small sources across departments and PIs.
cGMP producers needing lot traceability, activity at reference time, and validation-grade records.
Radiography, gauging, and well-logging operators managing sealed sources and leak tests in the field.
Licensed sites needing rigorous inventory control, waste decay tracking, and inspection readiness.
Why Marichi
Most teams stitch together spreadsheets, paper logs, and generic tools. Marichi was purpose-built for radioactive material, with the math, the audit trail, and the regulators in mind from day one.
Decay math, wipe tests, transport index, half-life clearance, and license limits are native concepts — not custom fields in an off-the-shelf tool.
21 CFR Part 11 electronic records and signatures, immutable WORM history, and ALCOA+ data integrity make every record defensible.
Automatic decay calculations, calibration and expiry alerts, and scheduled exports cut the manual errors that create compliance gaps.
A unified multi-site model with a cross-site RSO view replaces disconnected, per-facility tracking — with role-based access throughout.
Web-based and responsive, with camera capture for CoAs and dropdowns wired across modules — usable on a tablet in the lab, not just at a desk.
Designed alongside practicing radiation safety officers and delivered with the support of a partner that understands regulated science.
Marichi is engineered to support the frameworks your inspectors hold you to.
