Gamma spectroscopy tools
HelpScreening and training calculators for energy calibration, efficiency calibration, ROI activity estimation, FWHM/resolution, and MDA-style approximations. Physics formulas are implemented in lib/physics/spectroscopy.ts.
Spectroscopy training/support scope
This module provides spectroscopy calculation support and training estimates only. It does not replace calibrated spectroscopy software, detector QA, laboratory procedures, peak fitting, interference review, nuclide identification, or certified counting laboratory methods.
Energy calibration
Spectroscopy data audit
- Selected tool
- energy-calibration (#energy-calibration)
- Method
- Simple linear calibration
- Inputs
- user-supplied
- Calibration/source note
- —
- Warning level
- elevated
- Report/export readiness
- blocked
Add calibration source note (source peaks/reference) to enable report export.
- Simple linear channel-energy model only; no nonlinear terms or drift corrections.
Report export blocked
- Calibration/source note is required for report export on this spectroscopy tool.

Slope: 1.3448607 keV/channel
Intercept: -11.859016 keV
Predicted unknown energy: 996.78648 keV
| Channel | Energy | Predicted | Residual |
|---|---|---|---|
| 100 | 122.000 | 122.627 | -0.627049 |
| 500 | 661.700 | 660.571 | 1.12869 |
| 1000 | 1332.50 | 1333.00 | -0.501639 |
- Simple linear calibration only; residual review is required before relying on calibration transfer.
- Extrapolation outside calibration channel range has increased uncertainty.
energy = slope × channel + intercept
