“…As a result of these measurements and calculations, the detector-source distances with the best efficiency values were determined for both alpha detectors. The same information about the measured efficiency is shown in Figure 5, where we see that the detector efficiency depends on the measurement geometry and the detector-source distances (Calin et al, 2013b). Therefore, it is concluded that the detector-source distance should be as small as possible in order to obtain high measurement efficiency.…”

The calibration parameters of a high resolution two-chamber alpha spectrometer dedicated to detect alpha radiation in environmental samples were evaluated and confirmed using a certified standard source containing 237 Np, 241 Am and 244 Cm nuclides. The resolution and efficiency characteristics for the two ion-implanted solid state detectors (ULTRA AS series) in this system were evaluated at all possible detector-source distances. The characteristics related to the performance of alpha detectors against the alpha radiation emitted from the standard source used in the measurements and the results obtained were compared in detail.

“…The differences in the efficiency for the different source-toscintillator distances result from geometrical factors. This is because the efficiency of the detector is constant regardless of the detected alpha particle's energy [10]. The differences observed in the measurements and Monte Carlo simulations might be attributed to the inhomogeneity of the Am-241 source and the Ce:GAGG scintillator, and errors in the geometrical parameters such as source radius, scintillator thickness, and source-to-scintillator distance.…”

An alpha imaging detector acquires a two-dimensional distribution of a sample that emits alpha particles. For the quantitative analysis of the image of an alpha-emitting sample, the individual energies of the alpha particles must be identified, which can be achieved using the spectrometric method after detector calibration. In this study, an energy and efficiency calibration method was investigated to assess an alpha imaging detector. The calibration was performed using a single standard source of Am-241 based on the energy loss characteristic of an alpha particle. The feasibility of the calibration method was evaluated using another source, Ac-225. The calibrated alpha imaging detector was evaluated in terms of energy resolution and detection efficiency, and the alpha imaging detector was found to be efficiently calibrated using a single standard source. The calibrated alpha imaging detector appears promising for the quantitative analysis of samples that emit alpha particles.
