Background: Two of the important radionuclides which are entered to environment and human diet are radium-226 (226Ra) and cesium-137 (137Cs). It is clear that the methods for preparation of foods such as peeling, washing, cooking or frying can affect the dose which is received by human due the to consumption of foodstuffs. An experiment has been performed at the environmental monitoring section...

In an Environmental Radioactivity Laboratory, samples from several products are analyzed, in order to determine the amount of radioactive products they contain. A usual method is the gamma activity measurement of these samples, which typically requires the use of High Purity Germanium Detectors (HPGe). GMX (n-type) detectors can be found among this group of detectors. They have a high efficienc...

High purity germanium (HPGe) detectors are ubiquitous in nuclear physics experiments and are also used in numerous low radioactive background detectors. The effect of the position of Co and Cs point sources on the shape of spectra were studied with Monte Carlo and HPGe detector measurements. We briefly confirm previous work on the position dependence of relative heights of peaks. Spectra taken ...

Events recorded in Au+Au collisions at a beam energy of 1.23 GeV/u have the highest multiplicities measured with HADES [1]. The track reconstruction and particle identification in the high track density environment are challenging. In case of dileptons: (i) A Ring Imaging Cherenkov detector (RICH) [2] is essential since it is the most important detector component for single lepton identificatio...
