| Zusammenfassung: | The files contain the Grid Ionization Chamber (GIC) spectra of the americium-spiked concrete samples and supplemetary files used for the data analysis. The concrete samples were spiked with a standard americium solution with activities ranging between 200 kBq and 20 MBq with the spiking area of 3 cm x 3 cm. |

The measurement time (in seconds) is reported in line 7 of each file. The energy calibration of the spectrum is given by Cal-zero and Cal-Slope in lines 9 and 10. format: .txt recommended software: parameters: - block: Pretest and recovery research object: Data analysis method: The recovery of the sample is quantified as the measured activity divided by the applied activity. The measured activity is obtained by summing all counts of the spectrum and dividing the sum by the duration of the measurement. format: .xlsx recommended software: Microsoft Excel 2007+ - block: The measurement campaign of 14 Sep 2023 research object: Measuring alpha activity via the alpha spectrum obtained using the Grid Ionisation Chamber (GIC) method: GIC measures the energy distribution (spectrum) of alpha particles.
