We conducted a community‐scale field study to evaluate whether trace element contaminants derived from coal combustion residuals and nuclear fission products alter the dynamics of haemosporidian blood parasites, dipteran vectors, and avian hosts in riparian and wetland habitats in South Carolina, USA.

A novel HPGe-BGO pair spectrometer
We report on a novel design for a HPGe-BGO pair spectrometer with the aim to enhance the performance of existing HPGe detectors for high-energy γ-rays. In addition, the BGO shield as a standalone detector allows for a use with the selective detection of ...

Novel method for determining of 137Cs in seawater using liquid scintillation counter
Abstract Robust and efficient monitoring of radiocesium in the marine environment has become increasingly important, especially following the Fukushima Daiichi Nuclear Power Plant accident. A liquid scintillation counter (LSC) has been used for 137Cs analysis—which was identified as one of the hazardous radionuclides; however, a major limitation of ...

New Developments in HPGe Detectors for High Resolution Detection
High-Purity Germanium (HPGe) detectors continue to be a fundamental tool in nuclear gamma spectroscopy. The tracking of the gamma interactions inside the HPGe crystals is opening a new era in the use of these detectors for both basic science and applications, but they have also shown that new R&D is necessary for the production of even better and more ...

ABSTRACT An accurate database of atomic fundamental parameters (FPs) is crucial for quantitative material analysis based on x‐ray fluorescence (XRF). Given the wide range of applications and the limited reliability of existing experimental FPs for the L subshells of platinum, we determined its partial L fluorescence yields and Coster–Kronig transition ...

An Extended Amplitude Range Readout Circuit for Charged Particle Detection–BEAR 2
Abstract Charge sensitive amplifiers (CSA) form the first stage of most detector readout circuits. The operating range of the readout circuits depends on the saturation limits of the Charge sensitive amplifiers, thereby limiting the range of the detector system as well. A number of methods have been introduced to extend the dynamic range of the readout

Gaia: segmented germanium detector for high‐energy X‐ray fluorescence and spectroscopic imaging
We present Gaia, a cryogenically cooled monolithic array of 96 high‐purity germanium pixel detectors integrated with a custom low‐noise application‐specific integrated circuit and a field‐programmable gate array‐based data acquisition system. The system achieves an average energy resolution of 711 eV at 122 keV and 253 eV at 5.89 keV, and serves as the

COMPUTATION OF THE FULL ENERGY PEAK EFFICIENCY OF AN HPGE DETECTOR USING A NEW COMPACT SIMULATION ANALYTICAL APPROACH FOR SPHERICAL SOURCES [PDF]
The full energy peak efficiency of HPGe detector is computed using a new analytical approach. The approach explains the effect of self-attenuation of the source matrix, the attenuation by the source container and the detector housing materials on the ...

Does an Increase in Number of Deep Burrowing Earthworms Enhance Subsurface Nutrient Losses?
ABSTRACT Deep burrowing earthworms Lumbricus terrestris can be abundant along subdrain trenches, creating macropores that may serve as preferential flow paths for particles and agrochemicals to subdrains. We examined L. terrestris abundance, subdrain water discharge, and nutrient loss trends during 2002–2022 in an arable no‐till clay soil with an ...

Sorption is a well‐known method for radionuclide removal, but the high cost of synthetic sorbents constrains its application. This study investigates the potential of locally sourced diatomite from Kariandusi, Kenya, as a cost‐effective sorbent for capturing barium (Ba), cobalt (Co) and zinc (Zn) from radioactive liquid waste.
