What’s New Version 4.0.0
Major update for professional nuclear and radiation workflows:
- Added a Gamma Spectrum Simulator with nuclide lines, resolution, live time, background, and dead-time controls.
- Expanded nuclide details with levels, gamma transitions, electrons, fission yields, and richer nuclear data views.
- Improved decay and dose calculators, theranostics dosimetry, binding-energy charts, and reactor reference views.
- Refined the mini-program style UI, localization, and iPad layouts for faster lookup and clearer charts.
Description
Nuclides is a professional reference and calculation toolkit for nuclear technology, radiation protection, nuclear medicine, reactor data, and education.
Key features:
1. Look up elements and nuclides, including half-life, decay modes, parent and daughter nuclides, radiation energies, and emission probabilities.
2. Explore extended nuclear data, including excited levels, gamma transitions, electron data, fission yields, nuclear moments, and ENSDF evaluation information.
3. Simulate gamma spectra from nuclide gamma-ray data with controls for live time, energy resolution, background, dead-time loss, and related detector parameters.
4. Run decay calculations, activity estimation, dose-rate estimation, effective dose estimation, radiation dose comparison, and unit conversions.
5. Use theranostics dosimetry tools for time-activity data, cumulated activity, and simplified MIRD relationships.
6. Consult radiation safety atlas entries, radiopharmaceutical references, material densities, physical constants, binding-energy charts, toxicity information, and the INES scale.
7. Browse nuclear power plant data, operating records, advanced reactor references, and small modular reactor information.
Nuclides is designed for professionals, students, and users who need fast nuclear data lookup, radiation calculations, and clear technical references.
