Effect of an extract of Centella asiatica on the biodistribution of sodium pertechnetate (Na^99mTcO₄) and on the fixation of radioactivity on blood constituents [PDF]

, 2008
This study evaluates the effects of an acute treatment with a Centella asiatica (CA) extract on the biodistribution of the radiopharmaceutical Na99mTcO4 and on the fixation of technetium-99m on blood constituents. Wistar rats were treated with CA extract

Radium removal from mine waters with the application of barium chloride and zeolite: comparison of efficiency

Journal of Sustainable Mining, 2019
In several coal mines in the Upper Silesian Coal Basin (USCB), in Poland, radium removal from mine water was necessary in order to mitigate the negative results of radium release with mine effluents.

Brain delivery of vasoactive intestinal peptide (VIP) following nasal administration to rats [PDF]

, 2003
The aim of this work was to study in rats the nasal route for the brain delivery of the vasoactive intestinal peptide (VIP) neuropeptide. After evaluating VIP stability in solutions obtained from nasal washes, the effect of formulation parameters (pH 4-9,

Two-proton radioactivity

, 2008
In the first part of the present review paper, experimental results which lead to the discovery of two-proton radioactivity are reviewed. Beyond two-proton emission from nuclear ground states, we also discuss experimental studies of two-proton emission ...

Study on Separation of Rhenium, a Surrogate Element of Fissiogenic Technetium, from Aqueous Matrices Using Ion-Selective Extraction Chromatographic Resins

Separations, 2023
Long-lived fissiogenic technetium, 99Tc (half-life, 2.11 × 105 yrs), is a byproduct of the 235U and 239Pu fission in nuclear reactors and is a major component in nuclear waste.

Efficiency calibration of a well-type HPGe detector using experimental and Monte Carlo simulation techniques [PDF]

Nuclear Technology and Radiation Protection, 2020
Well-type high-purity germanium detectors are well suited for the analysis of small samples, as they combine high detection efficiency with low background radiation. The well geometry however makes efficiency calibration more difficult than that

The neglected activation of tantalum in reduced activation materials

Nuclear Materials and Energy, 2023
Due to the expression of “reduced activation”, the severe radioactivity of tantalum (Ta) after neutron irradiation in early decay years is easily neglected. In the presented study, after an irradiation of only 0.3 dpa by fission neutron and followed by a
