Abstract: Data measured with an IRSD and AlphaGUARD for the determination of the Rn-222 emanation from Ra-226.
Other: EMPIR projects are co-funded by the European Union’s (EU) Horizon 2020 research and innovation programme and the EMPIR participating states.

# Subfolders 50L, 500L

Subfolders contain experimental IRSD data (see https://doi.org/10.3390/ijerph19020840 for reference about the technique) with an AlphaGuard spectrometer, operated in a closed volume of (48.6 ± 0.4) L and (667.3 ± 0.7) L respectively.

- Subfolder "IRSD" contains the IRSD data:
- File __Spectra.csv: Full alpha-spectrometric data acquired by the IRSD and derived peak areas (see https://doi.org/10.3390/ijerph19020840, Appendix A, for method description)
- File __InferenceData.csv: SLDS-deconvolution results (see https://doi.org/10.3390/ijerph19020840, Appendix B) yielding current remaining Rn- and Ra activities, emanation, and full covariance information.

- Subfolder "AlphaGuard" contains measurement data of different AlphaGuards operated in these volumes. Timestamps are referred to the CET time zone (UTC+1)

All files are ASCII-coded CSV files. They may be opened with a spreadsheet program (LibreOffice), a text editor or via script, e.g. in Python.
