An Aerial Gamma Ray Survey of the Surrounding Area of Sizewell Nuclear Power Station [PDF]

, 1997
<p>An airborne gamma ray survey of the surroundings of the Sizewell nuclear power station was conducted to define the present levels of radiation background for reference purposes. A twin engine helicopter fitted with a high volume NaI detector and

Gamma spectrometric analysis of lower Danube samples from Romania [PDF]

Nuclear Technology and Radiation Protection
This paper focuses on the natural and anthropogenic radioactivity of sediment samples from key spots located in the Lower Danube area and the Danube Delta region. The idea of the study is to confirm that gamma spectrometry is an efficient method

The Gamma-ray Spectrometry of Fission Products, (V)

Journal of the Atomic Energy Society of Japan / Atomic Energy Society of Japan, 1961
The calculation of scintillation spectra for the broad parallel gamma rays emitted from U235 fission products incident on a right circular cylindrical NaI (Tl) crystals is presented. Typical scintillation spectra from fission products are presented. The parameters of the spectra were tabulated as functions of time after fission.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Applications of ultra-high resolution microcalorimeter gamma-ray spectrometry

Frontiers in Nuclear Engineering
Ultra-high energy resolution microcalorimeter gamma-ray spectroscopy—with energy resolution 5 to 10 times better than observed in spectra obtained by commercial-off-the-shelf high purity germanium detectors—is an enabling technology for ultra-precise ...

Gamma-ray spectrometry of humans at the University of Utah [PDF]

Radiation and Environmental Biophysics, 1979
A human total-body counter was designed and built with two 20 X 10 cm NaI (Tl) crystals suspended over an "isoresponse surface" upon which the subject reclines. This surface is curved from head to knee and from left to right, so that a gamma-ray emitting object is detected with equal efficiency when placed anywhere upon it. The positioner and detectors

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Gamma-ray spectrometry for burning plasma scenario developments

Nuclear Fusion
Gamma rays generated in nuclear reactions have been used on the Joint European Torus (JET) for more than a quarter of a century to study the main mechanisms of fast-ion slowing down, redistribution as well as for the development of optimal plasma ...
