Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Absorption of radionuclides from the Fukushima nuclear accident by a novel algal strain. [PDF]

open access: yesPLoS ONE, 2012
Large quantities of radionuclides have leaked from the Fukushima Daiichi Nuclear Power Plant into the surrounding environment. Effective prevention of health hazards resulting from radiation exposure will require the development of efficient and ...

Updated Incidence of Thyroid Cancer in the North East Region of Romania after 35 Years of Chernobyl Fallout. Is There a Link between?

open access: yesDiagnostics, 2021
Thyroid cancer (TC) represents a worldwide problem, the consistent growth of the incidence increment issues about management of risk factors and curative treatment. Updated statistical data are not complete in the North East region of Romania and need to

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]

open access: yesA&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

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]

open access: yes, 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]

open access: yes, 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.

Seaweed against strontium and preussian blue against cesium

open access: yesRangifer, 1988
The fact that alginates bind strontium and cyanates bind cesium and are capable of removing these elements from living organisms is scientifically verified. Zeolites offer another possibility for exchange of these ions.

The use of stable Cs and Sr as proxies for the estimation of radionuclide soil-plant transfer factors [PDF]

open access: yesЯдерна фізика та енергетика
Transfer factors are key inputs for modelling the transport of radionuclides in the environment and for assessment of risk to humans and wildlife. However, for many combinations of soil conditions, plant species (products), and radionuclides, such ...

Strontium Ferrite Under Pressure: Potential Analogue to Strontium Ruthenate [PDF]

open access: yesPhys. Rev. B 109, 165146 (2024), 2023
Despite the significant attention it has garnered over the last thirty years, the paradigmatic material strontium ruthenate remains the focus of critical questions regarding strongly correlated materials. As an alternative platform to unravel some of its perplexing characteristics, we propose to study the isostructural and more correlated material ...
