Physical features of accumulation and distribution processes of small disperse coal dust precipitations and absorbed radioactive chemical elements in iodine air filter at nuclear power plant [PDF]
Russian: Physics of radiation damages and radiation materials, no.
4(89), pp. 164-168, 2006, 2012 The physical features of absorption process of radioactive chemical elements and their isotopes in the iodine air filters of the type of AU-1500 at the nuclear power plants are researched. It is shown that the non-homogenous spatial distribution of absorbed radioactive chemical elements and their isotopes in the iodine air filter, probed by the gamma ...

Calibrating Iodine Cells for Precise Radial Velocities [PDF]
, 2019 High fidelity iodine spectra provide the wavelength and instrument calibration needed to extract precise radial velocities (RVs) from stellar spectral observations taken through iodine cells. Such iodine spectra are usually taken by a Fourier Transform Spectrometer (FTS).

On-line Excited-State Laser Spectroscopy of Trapped Short-Lived Ra$^+$ Ions [PDF]
, 2010 As an important step towards an atomic parity violation experiment in one single trapped Ra$^+$ ion, laser spectroscopy experiments were performed with on-line produced short-lived $^{212,213,214}$Ra$^+$ ions. The isotope shift of the $6\,^2$D$_{3/2}$\,-\

Neutron-scattering studies of arsenic sulphide glasses [PDF]
arXiv, 2004 High-resolution neutron-scattering measurements have been performed on bulk glasses of As2S3 and As2S3I1.65 at a spallation neutron source. For the case of As2S3, an isotopic-substitution experiment involving the S isotope has allowed some of the various pair correlations contributing to the second peak in the radial distribution function to be ...

High-Sensitivity Iodine Imaging by Combining Spectral CT Technologies [PDF]
arXiv, 2021 Spectral CT offers enhanced material discrimination over single-energy systems and enables quantitative estimation of basis material density images. Water/iodine decomposition in contrast-enhanced CT is one of the most widespread applications of this technology in the clinic. However, low concentrations of iodine can be difficult to estimate accurately,

I-Xe analysis of a magnetic separate from Lodranite GRA95209 [PDF]
, 2002 I-Xe dating of a magnetic mineral separate from lodranite GRA95209 suggests that peak temperatures (and therefore melt migration) occurred early, at least a few million years before closure of the I-Xe system in phosphates from ...

Active laser frequency stabilization using neutral praseodymium (Pr)
, 2009 We present a new possibility for the active frequency stabilization of a laser using transitions in neutral praseodymium. Because of its five outer electrons, this element shows a high density of energy levels leading to an extremely line-rich excitation

Thyroid cell irradiation by radioiodines: a new Monte Carlo electron track-structure code
Brazilian Archives of Biology and Technology, 2007 The most significant impact of the Chernobyl accident is the increased incidence of thyroid cancer among children who were exposed to short-lived radioiodines and 131-iodine.
