Contribution of luminosity on detected counts and related double detections (CMP2), triple detections (CPM3), and Becquerel values over a measurement period of up to 4  days, with varying measurement times and different scintillation cocktails. Counter background measurements were carried out with 1, 2, 10, and 60 min of measurement time. A time series for each background measurement was established by repeating the analysis of the sample for 200 times (for experiment with a measurement time of 1 and 2 min) and 100 times (for experiments with a measurement time of 10 and 60 min). Three different scintillation cocktails (ROTISZINT, Carl Roth; AquaLight+, Hidex; and Ultima GOLD XR, and Perkin Elmer) were investigated with the above mentioned measurement times.
