“…Nisti et al [5] evaluated "a priori" counting times as a function of the preset minimum detectable amount MDA, for time counting optimization in gamma-ray spectrometry. Several set-ups including four HPGe detectors, four counting geometries and different counting times (1,000 s, 5,000 s, 10,000 s, 15,000 s, 50,000 s, 100,000 s and 150,000 s), were employed.…”

“…This time is related to sample composition, radionuclide being analyzed, background radiation, the geometry of detection flask and detection system (detector, shielding, and associated electronics). Time counting optimization is also described, as an additional step in routine gamma-ray spectrometric measurements and automated spectral analysis which are used to control and assess the quality of the measurement and analysis [5][6][7][8].…”

“…Some samples were prepared and measured for fourteen different counting times, ranging from 300.00 to 259,200.00 s. The obtained results were compared to the reference values from solutions with well-known activity concentrations samples, for minimum detectable amount (MDA) calculation [6,8]. A counting time of 86,400 s was found to be generally sufficient to reach the agreement between the preset and actual counting times.…”

“…Neste trabalho foi adotado o tempo de contagem das amostras em 150.000 segundos, onde estudo realizado porNISTI et al (2009) demonstrou que esse tempo é ideal para medidas ambientais, portanto, otimiza-se o processo por meio da geometria e tempo de contagem de modo que se tenham limites de detecção aceitáveis(SHWEIKANI, 2015). Segundo CAVALCANTE (2017) após levantamento dos valores de Concentração Mínima Detectável (CMD) e seguindo os procedimentos sugeridos pelos autores citados, os valores obtidos apresentam pontos a partir dos quais os valores de CMD são aproximadamente nulos e constantes…”
