Growth Responses of Holcus lanatus L. (Velvet Grass) in Soils Contaminated with Cesium or Strontium
Soil SystemsRadiocesium (r-Cs) and radiostrontium (r-Sr) released from nuclear accidents (e.g., Chornobyl, Fukushima) and routine operations (reactors, reprocessing) pose environmental and health concerns.

Radiation Protection and Environment, 2017 Natural and artificial radioactivity appears to be different in different geological regions. Moreover, the radionuclides may migrate to the deeper region of the earth after deposition, and the depth profile of a radionuclide reveals information on the ...

The discovery of radioactivity
Comptes Rendus Physique, 2017 The radioactivity of uranium was discovered in 1896 by Henri Becquerel who, starting from a wrong idea, progressively realized what he was observing, regularly informing the French Academy of Sciences of the progress he was doing. In the next years, it was found that thorium was radioactive too, and two new radioactive elements, polonium and radium ...

The light curve in supernova modeled by a continuous radioactive decay of $^{56}$Ni [PDF]
published in Advances in Applied Physics, Vol. 1, 2013, no. 4,
143-147, 2014 The UVOIR bolometric light curves are usually modeled by the radioactive decay. In order to model more precisely the absolute/apparent magnitude versus time relationship the continuous production of radioactive isotopes is introduced. A differential equation of the first order with separable variables is solved.

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

Stellar Radioactivities and diffuse gamma-ray line emission in the Milky Way [PDF]
arXiv, 2002 After a short historical introduction to the field of gamma-ray line astronomy with radioactivities, I present an overview of recent results concerning the massive star yields of those radioactivities. I comment on the implications of those results (concerning long-lived radioactivities, like Al-26 and Fe-60) for gamma-ray line astronomy, in the light ...
