Analysis of surrogate post-detonation urban debris (SPUD) gamma rays and self-attenuation
… analysis used to model the efficiency of a High-Purity Germanium detector (HPGe) as a function of source density and volume was conducted using MCNP.

Characterization of volcanic ash from 2010 Mt Merapi, Indonesia eruption by neutron activation analysis and leaching analysis
… TRIGA research reactor in conjunction with a high purity germanium detector (HPGe) with a Compton suppression system. The leachate was analyzed by an inductively coupled plasma mass spectrometer (ICP-MS), and the results were compared to the original material present in the ash. Several …

Using Cesium 137 to Understand Recent in Cave Sedimentation in the Tongass National Forest, Southeast Alaska
… areas were analyzed for 137Cs on the EG and G High Purity Germanium detector at the Western Kentucky University Applied Physics Institute for a period of 12 hours. Results from each site were obtained in terms of peak area (net counts) and then converted into international units (Bq/Kg). …

An evaluation of the natural radioactivity in the soils of Okahandja and Karibib, Namibia
… in well-labelled 500 ml plastic bottles. A High Purity Germanium detector (HPGe) was used to measure the gamma ray spectra of the samples. The intensities of selected gamma lines were used to calculate the activity concentrations of the gamma emitting radionuclides 238U, 232Th, and 40K. The …

Plasma characterisation of an electron cyclotron resonance ion source by means of x-ray spectroscopy
… measurements. The measurements were done with a high-purity germanium detector and processed with the DGF Pixie-4 module. Analyses of the measured spectra were done with subroutines written in Root. From the measured result, it was concluded that by increasing the incident microwave power from 50 …

In-situ measurements of radon concentrations in soil gas at a site on the Cape Flats
… some of the depths were not considered due to a high water table.) Atmospheric temperature, air humidity, wind speed and atmospheric pressure were measured using a portable weather tracker (Kestrel 4000). The highest radon concentrations recorded were 11000 ± 776 Bq.m-3 and 26900 ±1370 Bq.m-3 at …

Characterization of the Neutron Irradiation System for use in the Low-Dose-Rate Irradiation Facility at Sandia National Laboratories
… was used to ascertain the neutron spectra. A high purity germanium (HPGe) detector was used to characterize the photon spectrum. The experimentally measured spectra and the MCNP results compared well. Once the MCNP model was validated to an adequate level of confidence, parametric analyses was …
