Two measurement systems, one being comprised of three HPGe detectors and the other being a 4π measurement system of the assembly of 10 sets of scintillation detectors, were compared for their measurement performance in operations of radioactive waste drum radioactivity measurement and clearance and release operation of decommissioning. The system features of the former were high costs, capable ...

Decontamination and decommissioning (D & D) requires the characterization of large surface areas such as soils, walls, and floors. To address the identification and quantification of radioactive material in these problematic surroundings, a portable high-resolution gamma-spectrometry system has been developed. The system was tested using the calibrated concrete slabs at Grand Junction, Colorado...

Abstract $$\gamma $$ γ -ray tracking is based on a new generation of position sensitive high-purity germanium (HPGe) detectors. A novel type cluster detector was successfully developed and assembled for the high-resolution spectrometer Advanced Gamma Tracking Array AGATA. The core part consists three encapsul...

In this research, polymers were fabricated through combining polyester, boron oxide (B2O3), and Tellurium (TeO2). B2O3 has good neutron absorption TeO2 is not only highly dense (5.670 g/cm3) but also environment-friendly, compared to PbO, as well being a photon absorber. The radiation protection features for five investigated samples examined utilizing an HPGe detector point sources Am-241, Cs-...

Coherent and incoherent scattering cross section measurements have been carried out using a HPGe detector on elements in the range of Z = 13 50 using Am gamma rays. The cross sections have been derived by comparing the net count rate obtained from the Compton peak of aluminium with the corresponding peak of the target. The measured cross sections for the coherent and incoherent processes are co...
