MIRDcalc S Value Database
This downloadable ZIP archive contains a comprehensive set of reference S values used in the MIRDcalc software, supporting organ-level internal dosimetry calculations based on the MIRD schema. Developed using data and methods aligned with ICRP Task Group 96 publications and recommendations, as well as radionuclide decay data from ICRP Publication 107, Supplementary Material, the database includes:
- 333 radionuclides with detailed decay spectra
- Reference phantoms for adults and children (ICRP Publications 110 and 143)
- Over 80 source regions and 40+ target regions
- Full energy spectrum integration for beta emitters
- Support for alpha and alpha-recoil contributions
- CSV format for easy integration into research pipelines
Each CSV file is named according to the radionuclide, phantom type, and age/sex group it applies to.
