Numerical studies on the link between radioisotopic signatures on Earth and the formation of the Local Bubble. II. Advanced modeling of interstellar 26Al, 53Mn, 60Fe, and 244Pu influxes as traces of past supernovae in the solar neighborhood [PDF]
A&A 680, A39 (2023), 2023 Measurements of long-lived radioisotopes provide a means, completely independent of other observational channels, to draw conclusions about near-Earth supernovae (SNe) and thus the origin of the Local Bubble (LB). First and foremost in this context is 60Fe, which has already been detected across the Earth and on the Moon. Using Gaia EDR3, we identified

Liquid scintillation counting at the limit of detection in biogeosciences
Frontiers in Microbiology, 2023 Liquid scintillation is widely used to quantify the activity of radioisotopes. We present an overview of the technique and its application to biogeosciences, particularly for turnover rate measurements.

Concentration of rhenium from dilute sodium chloride solutions [PDF]
Journal of the Serbian Chemical Society, 2008 The conditions for the desorption of rhenium from the anion exchange resin Dowex 1-x8 by HNO3, HCl, H2SO4 and NaOH were determined. The solution (5.0×10-3 mol dm-3 Re in 0.15 mol dm-3 NaCl) was passed through a column containing 0.10 g of the resin.

A new method in the production of Ac-227, Ra-228, Th-228 and U-232 on Thorium target from different perspective for use in Radioisotope Power Systems and Nuclear Batteries [PDF]
, 2021 We recommended a new method from different perspective for the production of Ac-227, Ra-228, Th-228 and U-232 radioisotopes which have an important potential for use in radioisotope power systems (instead of Pu-238) and nuclear batteries, based on long half-life, high power density and low radiation level.

Prevalence of short-lived radioactive isotopes across exoplanetary systems inferred from polluted white dwarfs [PDF]
, 2022 In the Solar System short-lived radioisotopes, such as 26Al, played a crucial role during the formation planetary bodies by providing a significant additional source of heat. Notably, this led to early and large-scale melting and iron core formation in planetesimals and their loss of volatile elements, such as hydrogen and carbon.

Investigation of alpha particle induced reactions on natural silver in the 40-50 MeV energy range [PDF]
Nuclear Instruments and Methods B 436(2018)119-129, 2021 Natural silver targets have been irradiated by using a 50 MeV alpha-particle beam in order to measure the activation cross sections of radioisotopes in the 40-50 MeV energy range. Among the radio-products there are medically important isotopes such as $^{110m}$In and $^{111}$In.
