A new design of a galvanic sensor pulsed X-ray radiation is proposed, which flat electric capacitor with window in one metal lining and solid dielectric made single-crystal sapphire thickness 200-300 μm inside. The influence the surface roughness area on linear has been established. Tests have shown that, ultra-smooth polishing plate working to R q ≤ 0.2 nm, it possible provide detection X-rays...

This paper presents the phenomenon of directed nuclear radiation based on the analysis of Lobachevsky angle of parallelism. In spite of the wide application of Lobachevsky geometry in relativistic physics [1-3], one of its basic concepts, the angle of parallelism, has not received due interpretation. The angle of parallelism characterizes the closeness of a produced particle to the absolute in ...

introduction: ordered subset expectation maximization (osem), is an effective iterative method for spect image reconstruction. the aim of this study is the evaluation of the role of system matrix in osem image reconstruction method using four different physical beam radiation models with three detection configurations. methods: spect was done with an arc of 180 degree in 32 projections after i...

A simple and rapid method with low radiation exposure risk was developed for the determination of neodymium in spent nuclear fuel by capillary electrophoresis with laser-induced fluorescence detection using a fluorescent probe having a macrocyclic hexadentate polyaminocarboxylate structure. The concentration of Nd(III) in a spent nuclear fuel sample was determined with no interference from vari...

The radiation detection systems employed in radioanalytical chemistry laboratories have changed considerably over the past sixty years, with significant improvement realized since the early 1980s. Advancements in the areas of material science, electronics, and computer technology have contributed to the development of more sensitive, reliable, and user-friendly laboratory instruments. The four ...

Improving the Presage Polymer Radiosensitivity for Hot Cell and Glovebox 3D Characterization Adamovics, John; Farfan, Eduardo B.; Coleman, J. Rusty Health Physics (2013), 104(1), 63-67. RadBall is a novel, passive, radiation detection device that provides 3D mapping of radiation from areas where measurements have not been possible previously due to lack of access or extremely high radiation dos...

Recent advancements in radiation detection and computer vision have enabled small unmanned aerial systems (sUASs) to produce 3D nuclear maps real-time. Currently these state-of-the-art still require two operators: one pilot the sUAS another operator monitor detected radiation. In this work we present a system that integrates real-time visualization with semi-autonomous control. Our Virtual Real...

Abstract Radiation detection and imaging are used for nondestructive testing in the field of production technology, diagnosis treatment medical field, security activities at airports nuclear facilities. To improve sensitivity resolution radiation imaging, light scattering self-absorption scintillator media should be suppressed. Thick film scintillators with a thickness several tens micrometers ...

Objective(s): In recent years, the application of radiopharmaceuticals in nuclear medicine has increased substantially. Following the diagnostic procedures performed in nuclear medicine departments, such as myocardial perfusion imaging, patients generally receive considerable doses of radiation. Normally, radiation-induced DNA damages are expected following exposure to a low-dose ionizing radia...
