Advancements in the development of gamma-ray spectrometers (GRS) have led to small and lightweight that can be used under unmanned aerial vehicles (UAVs). Airborne GRS measurements are determine radionuclide concentrations ground, among which natural occurring radionuclides 40K, 238U, 232Th. For successful applications these sensors, it is important absolute values measured. To extract concentr...

We measured full energy peak efficiency of High-Purity Germanium detector which is important for gamma-ray spectrometry experiments. A brief but very effective description on the basic formation of detector crystal and creation of signal pulse has been presented here. This article is furnished in such a way that the contents find useful and interesting to physics and electronics students, educa...

abstractbackground : the presence of primordial radionuclide in human habitats has always been a source of prolonged exposure. measurement of naturally occurring radionuclides in the environment can be used as baseline to evaluate the impact of non-nuclear activities and also routine releases from nuclear installations.   materials and methods: a total of 56 samples from 18 different foodstuff ...
