Determination of the HPGe detector efficiency in measurements of radioactivity in extended environmental samples

Análise Da Radiação Solar Nos Meses De Janeiro E Fevereiro Por Modelagem Computacional Usando Redes Neurais Artificiais

“…The experimental measurements were carried out using a coaxial p-type HPGe detector (model GC2518), manufactured by Canberra. The geometrical dimensions and spectrometric characteristics of the detector were verified by (MONTALVÁN-OLIVARES et al, 2017) and compared with those provided by the manufacturer. This detector has a nominal relative efficiency about 25% compared to 7.62 cm x 7.62 cm NaI (Tl)…”

“…Correction factors such as solid angle for the volumetric sample and self-absorption correction factors (Fself-abs) were also taken into account to calculations. If the reader is interested, additional details can be found in(MONTALVÁN-OLIVARES et al, 2017).Figure 2shows the efficiency curve in the energetic range of 53-1764 keV for the studied volumetric sample. Red points represent the efficiency values for the analytical gamma lines of interest.…”
