1. Geiger-Müller (G-M) Counter:
– Operating region and measurement statistics: Characteristic curve, determination of the threshold voltage and the plateau region.
– Dead time measurement using the dual-source method.
– Verification of the radioactive decay law.
2. Scintillation Detector (NaI/Tl):
– Εnergy calibration: ψorrelation of MCA (Multi-Channel Analyzer) channels with energies from known sources (e.g., Cs, Na).
– Gamma-ray spectrum analysis.
– Energy resolution: calculation of FWHM (Full Width at Half Maximum) for detector quality evaluation.
– Verification of the gamma-ray absorption law.
