The MAJORANA collaboration[1] aims to detect neutrino-less double beta decay (0νββ) in Ge, using an array of germanium p-type point contact detectors. An important factor in this effort is the minimization of backgrounds from any hardware which is needed to operate the detectors. In order to best understand and minimize this background, one must analyze the gamma spectrum from these pieces of h...

The subject of ttis chapter is the function and operation of the components of a gamma-ray spectroscopy system. In Chapter 3 it was shown that the output pulse amplitude from most gamma-ray detectors is proportional to the energy deposited by the gamma ray. The pulse-height spectrum from such a detector contains a series of full-energy peaks superimposed on a continuous Compton background. Alth...

  ABSTRACT   Background : The application of DU emanation for first time contaminated certain areas in the south west region of Iraq after the second Gulf war (1991). These contaminated areas were discovered in 1994. Radioactive contamination was detected using the nuclear enterprise PCM5/1 in soil samples collected from two regions near by grazing lands. This study was done for assessment of D...

The influence of NaNO2, HNO3 and H2SO4 on the structure and morphology of gamma-alumina was investigated by XRD, BET, SEM and FT-IR spectroscopy. Selected amounts of NaNO2, HNO3 and H2SO4 were added to a solution of aluminum isopropoxide (as a precursor for the boehmite synthesis). The boehmite samples were calcined at 350 and 600 ℃ to form the semi-crystalline high surface area gamma-Al2O3. Th...

volatile compounds generated from two types of polymeric laminated films, irradiated by gamma radiation at 8, 10 and 15 kgy, were investigated. activated carbon was used as a dry food simulant to trace the migrating compounds by gas chromatography/mass spectroscopy (gc/ms). the resulting data showed that the polyethylene terephthalate (pet)/polyethylene terephthalate (pet)/linear low density po...

The most common means of identification of gamma-hydroxybutyrate (NaGHB) involves using Fourier transform infrared spectroscopy (FTIR) or gas chromatography-mass spectrometry (GC-MS) of a suitable derivative. However, these methods may be complicated by possible shifts in chemical equilibrium between gamma-hydroxybutyric acid (GHB), GHB salts and the precursor lactone, gamma-butyrolactone (GBL)...
