Abstract: 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.
Other: The project 19ENV02 RemoteALPHA has received funding from the EMPIR programme co-financed by the Participating States and from the European Union’s Horizon 2020 research and innovation programme.
Remark: description of the individual files:
- block: Pretest and recovery
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. 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+
